I'll be at Thunder Valley Precision around 10am in the morning(Sunday)...if anyone is interested. Probably not..but I'll be the asshole with the Lil'B brake on a 300PRC with nobody sitting on the benches to either side.
Not working on anything in particular...except maybe practicing milling targets with the reticle, follow through with my trigger pull, spotting trace, and ofcourse some wind reading practice. My ADG brass got tied up in some kind of UPS fubar...won't be here until next week it seems....so not testing any new loads.
Just be shooting the same old boring 230gr A-Tips at around 2950fps.... 6.2mils at 1000 yards....well...depending on conditions...could get down to 6.1mils...or as high as 6.25mils....you never know...it could get tricky.
I'll need help spotting the mile target....My ZCO 5-27 MPCT3 won't be here for a month...so sporting a Vortex PST G2 3-15 for a little longer...I'll still hit it...but probably not the first shot.

Is this from Quickload? Data lines up pretty darn well with my results so far out of a 26" barrel with N565.
More ADG info:
Here is a pic of my first 50 along with my brand new 300 PRC seating die:
- Almost all bullets seated within 35lbs to 45lbs. A couple went a little higher, but never more than 55. Very consistent.
- I measured 10 loaded case necks, then stopped because they were all the same at .3365 in multiple angles, with a couple at .337. Again, used a .335 bushing.
- Weather permitting, I'm going to shoot these tomorrow morning. I have two sets of a ladder going from 71.2 to 74.0 at .2 gr increments - RL 26. Then I loaded a bunch at 72.2. Why 72.2? My RWS load for this is 71.8, and I'm guessing that my RWS cases have slightly less volume. So I upped the load a little for my "play" rounds. We'll see how close I got.

Nice seating die....gotta get me one too....after about 498394839 other things on my list.
I have some Berger 155.5 that I want to burn up for barrel break in and fire forming. Have Retumbo to drive them. Hodgdon's load calculator doesn't have a 155.5/Retumbo spec (or anything below a 168 bullet). The 168/Retumbo spec is at 81.2 gr for starting load. I was thinking of going even a bit lower at 80 gr to break in/fire form. Thoughts on this combination?
I would not go below the 80gr. point, you will have the chance of not fire forming brass at that low loading. If you shoot suppressed, you will see why. I would start at least 1 gr. over the 168 data to start.
Of course, depending on that powder and case capacity with that bullet type. Just trying to make sure of no wasted time and effort.
Dear Diary,
Went to Thunder Valley Precision today. 15.5 Mils at one mile. Hit both the 18" and 12" with ease. Got bored, came home Smiling from ear to ear now. 230gr A-Tips with 78.5gr N565.
I thought it couldn't be any better....until Tom told me about the upcoming ELR matches that will go out to 2500...and maybe 2600 and 2700 yards.
Going to be hard to sleep tonight.

Went out and ran a ladder with the new ADG/N565/ 230 A-Tips . Velocity was outright amazing , accuracy was the worst I thing I have ever seen out of any of my rifles EVER !! Not even sure the last time it was cleaned as it has been on the back burner for so long. I guess I should have ran a mandrel through the new brass as well , it was running about .003-.004 neck tension out of the box. I know the rifle will shoot as it would easily hold 1/2 with RL-26 and 230 A-tips with Hornady brass .....

Was pretty disappointed with these results, really wish I had some ADG brass. I am going to load up 6 rounds underneath 75.3 for the 245 and redo, and 8 rounds underneath 78.8 for the 215 and redo. Guess I will have to live with lower velocities than hoped for.

I'd be interested to see you getting that velocity. I'm not pushing my 28" barrel hard with RL26 at 74.8 grains with the 230 gAy Tips. Velocity is at 2882 with that load. A nice tack driver it is. All out of my DT. Dane at DMR Rifles will spin you up a barrel. He has some 300 PRC's in stock.
Going that short and making up the velocity might go through brass pretty quick. And good luck finding RL26
That’s only 3 grains over max published load... probably just a tad hot
Probably >80k psi. Brass and primers don’t even seemed phased
Guess I'll just loaf em there @2880
225 ELDM
77.3 H1000
CCI 200
5 shots
Apparently your barrel is bigger than mine?
I got that load from @Pools1 no testing, just loaded it and shot it.
I hope that guy above isn't going to be shooting against me in a few weeks at an ELR match....I'm still running 230's in Hornady Brass...guess maybe tomorrow I'll work up a 250gr load in ADG brass....probably not use Retumbo...I'll use N565 and get that puppy running a little hot.
Why 250's...because 15.5 mils at a mile using 230's is too much

Alex Pro Firearms makes thier AR in 300 PRC, 30 Nosler, and a few other calibers. Mine is being built as we speak
I was thinking the 225 and 230 weights initially.
Once I get the rifle I will do a full write up and review of the rifle. I know thier mags are proprietary and they can handle the longest 33 nosler saami spec rounds.

Ok...I'm about as crazy as anyone....but a 300PRC AR?.....I gotta ask... Why?
@LongRangeAggie the coal is 3.974 (inside dimension of the mag).
I should've explained more when I posted the 33 nosler info. What I meant is thier mag can handle 33 nosler.

I will be out of the office today doing load development for my new ADG Brass. I'll be using both N565 and RL-26. Bullet will be the 230gr A-Tip. I had to make some guesses on some 5 shot loads. loaded up the following for both N565 and RL-26
1. 76.0
2. 76.5
3. 77.0
4. 77.5
5. 78.0
-----------------Most like see too much pressure with the lower case volume----------------------
6. 78.5
7. 79.0
Then... 5 shot loadings of 77.0 and 78.0. I may be a little high...I may need to go back and revisit 76.0 and below if it gets too crazy due to decrease in case capacity. We will see. I should be able to post data later tonight.
This load testing will be done on virgin...non-fire formed brass. I will revisit and see the differences between these and fire formed. Using FGMM 210M primers. Weather looks like it may be 55F and a 3mph wind at time of testing...hopefully.
This should give me a good start for developing my loads for some upcoming ELR matches out to atleast 2500yds.

I think people may tell you that RL-26 is better at Temp Stability....UNTIL...it hits about 85F outside...or your rounds are cooking in the sun. Then RL-26 can get stupid. I've found N565 much more stable than N560 and N570 recently. I believe Vhitavouri advertises the N565 as temp stable....probably compared to the other two.
Maybe I can get you some data...but it will take a while as the season goes from stupid cold to stupid hot.
I just love living in NC where I shoot in the summer at 105degrees and hunt at 20 degrees
almost as fun as the 8k foot elevation change in western hunts
almost as fun as the 8k foot elevation change in western hunts
Well...back from the range with some data. Today didn't go like I thought it would. First off...let's look at some speeds...and let's clarify the environmentals.
Temp: 49F
Elevation: 913ft ASL
Pressure: 30.13
Humidity: 68%
Winds: 7mph steady right to left....full value wind.
Brass: ADG Virgin brass. Was full length resized mostly due to the necks being a little small...a little too tight for the the bullets.
Bullets: Hornady A-Tip 230gr
Primer: FGMM 210M
Case Over ALL Length: 3.8050"
Gun: 300PRC Defiance Deviant with 28" Bartlein 1-9tw. TriggerTech Diamond. Lil'B brake. MDT ACC Chasis.
Scope: Vortex Viper PST Gen2 3x15 EBR-2C
Ok...now let's talk about powder. I took Vhitavouri N565 and Reloader 26 and loaded 76-79 grains in .5 increments. Then I arbitrarily before hand loaded 5 of each powder at 77.0 grains and 78.0 grains. Now let's look at the numbers.
Vhitavouri N565
1. 76.0gr 2863fps
2. 76.5gr 2853fps <-- weird
3. 77.0gr 2882fps
4. 77.5gr 2898fps
5. 78.0gr 2917fps <-- ejector marks
6. 78.5gr 2916fps <-- ejector marks
7. 79.0gr 2940fps <-- ejector marks and a swipe
All above shot at large center of middle diamond.
Next a 5 shot group of 77.0 grains of N565
1. 2877fps
2. 2879fps
3. 2877fps
4. 2878fps
5. 2879fps
Ok...incredible SD's there....man that looks good....but had a flyer...could have been me...but during loading, some of the seating pressures were extremely tough compared to others. Being virgin brass...I'll give the low flyer a pass...but the group looked promising. Group is located in the upper right diamond.
Next a 5 shot group of 78.0 grains of N565
1. 2924fps
2. 2921fps
3. 2922fps
4. 2919fps
5. 2915fps
Again...nice consistent velocities for virgin brass....but small sample size....however...the group is horrible. Top left Diamond. Looks like a shotgun pattern. Not one single hole touching another. Barrel was cooled between all groups today. I'm not liking the looks of that group vertically.
N565 Target Pic:
What's that in the bottom right? It is a 'control' group...heh...actually it is 5 rounds of mixed powder and bullets that I was fouling the barrel with. I had just done a good scrubbing of the barrel the night before. You don't see 5 holes? The first shot was off paper to the right due to not looking at my scope dials and having the windage turrets moved 2 mils. IT's good to have those mistakes when not on the clock...when it doesn't matter.
Now....let us look at Reloader 26. The super unicorn stuff that I haven't had the pleasure of running in a 300PRC with a 230 grain A-Tip.
Again....loads from 76 to 79 grains in .5 grain increments. On target: Center large diamond.
1. 76.0gr 2932fps <---Well hello
2. 76.5gr 2946fps
3. 77.0gr 2964fps <---check for pressure...pressure ok
4. 77.5gr 2984fps <---check for pressure...still ok
5. 78.0gr 3005fps <---check for pressure....still ok...hmmm
6. 78.5gr 3033fps <---check for pressure...slight swipe visible.
7. 79.0gr 3071fps <---Holy crap....check for pressure...slight swipe visible....the last two the recoil had more of a snap.
Ok...I thought N565 was the answer to all my ills...but this RL-26 Unicorn Dust is looking like the real deal...so let's go shoot some 5 shot groups.
5 Shots of 77.0 grains of Reloader 26. On target: Bottom right hand diamond.
1. 2976fps
2. 2965fps
3. 2976fps
4. 2980fps
5. 2975fps
Well I can live with that. Pretty tight group...I know I caused that flyer by slapping the trigger...called it when I shot it.
5 Shots of 78.0 grains of Reloader 26. On target: Bottom left hand diamond.
1. 3028fps
2. 3031fps
3. 3029fps
4. 3031fps
5. 3030fps
Well...the speeds look fast...and consistent. I like that. The group looks pretty good too. The flyer wasn't me this time...well it could be...but I didn't call it when I shot...and everything felt good. Recoil pulse felt good. All brass looked good.
Reloader 26 Target:
So...this is a VERY small data set. However, RL-26 with these 230 grain A-Tips look real promising for the upcoming ELR events. I'll take this now fire formed brass and do some more load development in the coming week and see if the data stays the same or changes slightly.
It was a fun day....kinda cloudy and a chill in the air...but it beats having to go to work today.

Ok...now let's talk about powder. I took Vhitavouri N565 and Reloader 26 and loaded 76-79 grains in .5 increments. Then I arbitrarily before hand loaded 5 of each powder at 77.0 grains and 78.0 grains. Now let's look at the numbers.
Vhitavouri N565
1. 76.0gr 2863fps
2. 76.5gr 2853fps <-- weird
3. 77.0gr 2882fps
4. 77.5gr 2898fps
5. 78.0gr 2917fps <-- ejector marks
6. 78.5gr 2916fps <-- ejector marks
7. 79.0gr 2940fps <-- ejector marks and a swipe
All above shot at large center of middle diamond.
Next a 5 shot group of 77.0 grains of N565
1. 2877fps
2. 2879fps
3. 2877fps
4. 2878fps
5. 2879fps
Ok...incredible SD's there....man that looks good....but had a flyer...could have been me...but during loading, some of the seating pressures were extremely tough compared to others. Being virgin brass...I'll give the low flyer a pass...but the group looked promising. Group is located in the upper right diamond.
Next a 5 shot group of 78.0 grains of N565
1. 2924fps
2. 2921fps
3. 2922fps
4. 2919fps
5. 2915fps
Again...nice consistent velocities for virgin brass....but small sample size....however...the group is horrible. Top left Diamond. Looks like a shotgun pattern. Not one single hole touching another. Barrel was cooled between all groups today. I'm not liking the looks of that group vertically.
N565 Target Pic:
What's that in the bottom right? It is a 'control' group...heh...actually it is 5 rounds of mixed powder and bullets that I was fouling the barrel with. I had just done a good scrubbing of the barrel the night before. You don't see 5 holes? The first shot was off paper to the right due to not looking at my scope dials and having the windage turrets moved 2 mils. IT's good to have those mistakes when not on the clock...when it doesn't matter.
Now....let us look at Reloader 26. The super unicorn stuff that I haven't had the pleasure of running in a 300PRC with a 230 grain A-Tip.
Again....loads from 76 to 79 grains in .5 grain increments. On target: Center large diamond.
1. 76.0gr 2932fps <---Well hello
2. 76.5gr 2946fps
3. 77.0gr 2964fps <---check for pressure...pressure ok
4. 77.5gr 2984fps <---check for pressure...still ok
5. 78.0gr 3005fps <---check for pressure....still ok...hmmm
6. 78.5gr 3033fps <---check for pressure...slight swipe visible.
7. 79.0gr 3071fps <---Holy crap....check for pressure...slight swipe visible....the last two the recoil had more of a snap.
Ok...I thought N565 was the answer to all my ills...but this RL-26 Unicorn Dust is looking like the real deal...so let's go shoot some 5 shot groups.
5 Shots of 77.0 grains of Reloader 26. On target: Bottom right hand diamond.
1. 2976fps
2. 2965fps
3. 2976fps
4. 2980fps
5. 2975fps
Well I can live with that. Pretty tight group...I know I caused that flyer by slapping the trigger...called it when I shot it.
5 Shots of 78.0 grains of Reloader 26. On target: Bottom left hand diamond.
1. 3028fps
2. 3031fps
3. 3029fps
4. 3031fps
5. 3030fps
Well...the speeds look fast...and consistent. I like that. The group looks pretty good too. The flyer wasn't me this time...well it could be...but I didn't call it when I shot...and everything felt good. Recoil pulse felt good. All brass looked good.
Reloader 26 Target:
So...this is a VERY small data set. However, RL-26 with these 230 grain A-Tips look real promising for the upcoming ELR events. I'll take this now fire formed brass and do some more load development in the coming week and see if the data stays the same or changes slightly.
It was a fun day....kinda cloudy and a chill in the air...but it beats having to go to work today.
Ahh dangit, I was really hoping the N565 would come out on top! I got early pressure signs with my N565 load too. But it looks like RL26 is the winner. Although you might have something there at 77.0grs of N565, if that's what you want to use. Good report, thanks for sharing.
This is super impressive.... I’m having a barrel done but all these powders have been impossible for me to find.
Yep...hard to find powders..and suddenly everyone will have it in stock...when you have no monies...and then you get paid...and suddenly everyone is out of stock again....sucks being the average working man.
