COAL? I'm assume amax bullet? Barrel length? Twist? Maker? Curious as I'm thinking of developing something similar

Has anyone used IMR4320? I searched and cant find load data in this thread for it. Lymans has it listed but doesnt say what rifle was used. Im trying to work up loads for LR308 24" stainless HB 1-10 with 150gr bullets.
Does anybody have any good loads for the 185 OTM? I've got Varget, pp2000mr, cfe223, r17. Will be shooting them out of a 28" bartlein with 1:11.25. Lapua brass
I figured cfe and pp2000mr will have them zinging. But I like Varget for its stability.
Any help would be greatly appreciated.
How many here are using the Tula large rifle primers? Results?
I used a lot of the Wolf LR primers and had great results but have yet to break into a case of 5,000 Tula's. Just wondering what I'll see with the usual .308 powders like Varget, IMR-4064, IMR 8208 XBR, RL-15, etc.
Has anyone tried the Berger 168 Hybrids yet? I got some, but I'm not all that impressed yet. My normal load is 43.5 gr of Varget with the 175 OTMs that I have running 2720. I loaded the 168s at 44.0, but it's like they are shooting slower than the 175s. i.e. 4.4 mil at 600 v. 4.1 mil for the 175s. JBM says about 2625 for the 168s. Doesn't make sense with the heavier load. Also tried CCI 200 and Fed 210 primers - didn't really make a difference.
Maybe it's because the 168 hybrids have a considerably shorter bearing surface; therefore, generate less pressure? I'm just guessing though...
The other possibility is that I am getting down to the end of a 8# jug of Varget that I have had for a while. I noticed velocities falling off when I got to the end of a jug when I was shooting 155 Scenars. My thought was then was the bottle being open and closed many times allowed moisture to get in the powder causing the loss in velocity. Maybe I should Load a few with powder out of a fresh 1# bottle and see if that makes a difference. It's probably going to be important as I'll probably be using Varget on the 77gr 223 I'll be loading for the AR. I hate to throw away powder, but in this case it's less than 1/2 a pound and it's been nearly 8 months since it was originally opened.
That's actually a pretty good idea. I'd only need about 5 rounds of each to see. Plus I could pull 5 existing 175s and replace with 168s. I'd get a better idea what is happening.
Actually, I resize the case after pulling the bullet, with my Redding S full length die I can do that with the powder in it because I can remove the expander ball and decapping rod. Ya have to be careful, but it can be done.
My thought was to do both. 5 of each with the same load from the jug and 5 175s from a group that is shooting how I expect them too. Last 5 pulls, resize and replace from a good 175 batch with 168s.
I'll have a control group with the 5 "good" 175s, 5 175s and 5 168s from the same part of the jug, and 168s loaded in the pulls. I'm not just resizing the neck, but doing a full length resize. Could it induce a variable, maybe a minor one. My guess is I'll learn more from from the control group 175s to the comparison 175s and the comparison 175s to the comparison 168s. After that, I'll have a pretty good idea what to do next. I'm already pretty sure I need to push the load in with the 168s.
I got to test the 308 loads today to see what was going on. The good stuff, 175 OTMs 43.5 gr Varget, Lapua brass, CCI200, shot 4.2 mil at 600 today. Then I shot the 175s I loaded to the same spec from the Varget left in the 8# jug. It shot just a bit low, like .7 mil low. The 168 Target Hybrids were about .2 mil lower than that with the 43.5 load.
Looks like the powder has gone bad and the 168s don't have a BC that's quite as good as advertised.
I'm definitely no expert, but does the powder go bad from absorbing moisture? Could those silicon packets "reverse" this or prevent it? I looked and don't see an expiration date on my powder jugs but don't want an unopened 1lber going bad before I get to it either. I guess you could use the old stuff for plinking and fouler rounds so you don't need to scrap it. Thanks for posting the results of your experiment. I still haven't found the time to make it to the range to test the power pro/scenar 175 combo.
Well - explain how ammo I loaded a year ago out of the same jug of Varget is running at 2720 and the pieces I loaded recently are running 2550 with the exact same load. Jug is nearly empty and it's been sitting for a while.
Does anybody have any good loads for the 185 OTM? I've got Varget, pp2000mr, cfe223, r17. Will be shooting them out of a 28" bartlein with 1:11.25. Lapua brass

I have been working on a load with 185g Berger Juggies and found a node:
185g Berger juggernauts
Lapua brass
210m primer
43.0 Varget
Oal-2.915, .030 off lands
2630fps
There is another higher node around 45g or so and working on that.
Just getting into reloading for the .308
Got over 500 175gr SMKs, and a couple hundred Berger 175gr pills (some VLD, some hunting bullets).
Will be using Varget, 8208 XBR and IMR 4064.
Any pet loads for any of these combos?
Thanks!
For those powders I ended up with 43.5 gr Varget, 42.2 gr of 8208 XBR, and 42.3 Gr of IMR 4064. The standard caveat, "these were good loads for MY RIFLE.
I load all at 2.810" so I can load from the internal box mag and they all shoot sub 1/2 MOA, every day.
My 2cents as a recovering powderholic....
Unless you have real serous reasons to use a variety of powders, pick one. Develop for one. Sure it is nice to know other powders work, they will; but unless you enjoy having 1/2 empty, bottles or loads with variance in elevation curves; it is a time, barrel burning and expensive endeavor.
Same for bullets.. Caveats would be a target load and a hunting load.. That said, many people run separate systems for those activities anyway.

I have and I absolutely LOVE them. I am using the Tula KVB762 large rifle (NATO) primers and have completely shelved the Fed-210M's due to my results, which cover bullet weights from 155 to 208.
The pic below was taken 2 weeks ago out at my local range under the most "controlled" conditions I could manage. This includes shooting 5 shots with 210M's over the chrono (Magnetospeed) and then shooting a 5 shot (left target) group with the chrono removed. Then I reattached the chrono and shot a 5 shot group over the chrono using the Tula's, then removed the chrono and shot the 5 shot group on the right.
I should note that I shot 10 shots on the top target you cannot see in this pic to confirm zero, let the rifle cool for 15 minutes, then commenced the test with a 10 minute break between "tests". The idea behind that method, was to have comparable barrel temps for each of the 2 "tests".
I have a weather meter, and the conditions were extremely stable during this test. It was just before noon, so the temp had pretty much stabilized and was 76.4* F as indicated on the image. The entire "test" was completed in under 30 minutes, so I think that is about as good as it gets.
As indicated in the image, the group on the left with the Federal 210M primers shows POI roughly 1/2" high and slightly left of POA. The target on the right using the Tula primers was damn near perfect for me, and represents about as good as I am capable of shooting on any given day at 100 yards with a 308.
Needless to say, the Tula primers I have are performers, particularly with my powder lot, brass and bullets.
Lake City LR (2010) once fired brass was used for all loads.
Hornady 208 AMAX
Alliant Reloder-17
46.0 gr
2.191 to ogive / 2.842 OAL
These cartridges are far too long to feed from AI mags, so all rounds were single fed.
This cartridge configuration nets a .025" jump. I do not generally load or shoot "jammed".
The average speed is indicated on the target, but was 2586 (Fed primers) and 2580 (Tula primers).
The range is located 1050 feet ASL in California.
Hope that helps.
Excellent! Thanks for the info. I also have the large rifle Tula primers. I might have to break them out and see what happens.
Is that for the 175gr SMKs or Bergers? Thanks brother!
That's just too damned funny!! LOL!Nice to see the "numbers" and group for the Tula primers. I was able to pick up 5k of them before they started making them out of "unobtanium" and am almost out of Fed's. Too lazy to rework my loads yet for the Tula's
Looking at the Temp at the time these groups were shot makes me envious. Yesterday, at the range, it was a nice warm 24 degrees.
Funny side story:
Oldtimer shooting next to me brought in his propane tank with a heater on top. He'd set it up on the shooting bench next to me and was getting ready to light it. Just as he pushed the "safety button" in and held a match to the burner I sent a round downrange. I heard this loud shout and looked over. He was standing back and shaking all over. The "Boom" of my muzzle blast occured at the exact second that he put the match to the burner and he thought he'd just blown his ass up.
It took about 20 minutes for him to get his heart-rate back down and for both of us to stop laughing.
Thanks brother. I appreciate the feedback.I've shot both at that weight and found the results to be very similar at under 300 yards. I think the Bergers will fly longer, straighter, though.
