I’ve seen the same between 450’s and others. In 6.5x47 the br4 gives a touch better velocity but not worth the $$$. 450s have same low SD/ES just a few FPS lower. What load are you running in gt? I’m collecting data. My new barrel is in the works.

I run Varget 34.65 gr with Berger 109s in Alpha brass. Annealed every firing with an AMP. Drop powder with a ATV3.
2950 fps
Why do seating tests if you have a tuner on the way? Honestly, 6GT is so easy to load for. Pick a speed, load, and tune to close the groups up. Load development is maaaaybe 10-20 shots. I personally don't mess/test with jumping anything, especially Berger LRHT.
Don't waste precious components.
Don't waste precious components.
the br4 cost almost double the price, bought some today for almost 12 bucks per 100, freaking ridiculous .
nice i got my EC turner break about a month ago ,and believe me all of that seating depth , and waste of bullets, was gone in an instant, I just put it on and wasted about 5 rounds and my group was 1/4" at 200 yds. It is worth the $250 i paid for it.
He can do what ever caliber you want ,if I am not mistaken , he does everything in house
The regular tuner still needs to be turned by smith.
The tuner brake is an actual brake and the tuner on it is substantially smaller which can at times matter on larger contour barrels.
Hello,
Looking for insight into load development experiences using Varget and Shooters World Precision with the Barnes 112s and Hornady 108's along with Alpha OCD brass...
Kind regards,
Mike

Well I have the competition barrel contour and it fits perfectly can go a little bit thicker on the the barrel and still fit
@Dthomas3523 and it was done by Enrique over in Brownsvile.

Has nothing to do what I was talking about.
I’m referring to the size of the weight vs barrel contour and the effectiveness.
I tried joining the 6GT forum on Facebook to get some load data but have yet to get a reply. I'm trying to get loads for the 105 match burners for practice. I have the following powder:
IMR 4166
StaBall
IMR 4451
H4350
RL 17
Anyone have load data I'd greatly appreciate it.

Anyone have some some success with 112 match burners and h4350? Running in 26” barre and looking to run on the slower side. Less than 2900.
Perfect thank you. My first break in rounds were done slow with low grain bullets so I was thinking that I needed to be I. The 36 grain area. Much appreciated. How did they shoot for you?
Great thank you for the insight. That’s a big help as I would have started in the .02 range.
Thank you and much appreciated.
26" PVA Rock Creek cut rifle 7.5T
Prime Hornady once fired brass. Annealed, full length sized with .002 shoulder bump, trimmed 1.716, 21st Century .242 mandrel
I love to hear others thoughts on mandrel size?
My seating pressure was very consistent based on feel, but it felt low. I might try a .2415 mandrel if I can find one.
Charges were done on a chargemaster & I counted 4-5 kernels of the 555 to change scale by .1
109 Berger touches lands in my barrel @ 2.613
CCI #41
N 555
All seated at 2.583 COAL
37gr = 2809 avg SD 14
37.3gr = 2847 avg SD 11
37.6gr = 2865 avg SD 12.5
37.9gr = 2894 avg SD 9.8
38.2gr = 2907 avg SD 7.4 no pressure & not compressed
The above all shot under .5 moa with 37.9 and 38.2 a little better.
So based on that I loaded the rest @
38.6gr = 2920 avg SD 7.4
All velocities were with a Magnetospeed
Tweaked the 109 G7 to .298 to get AB lined up at 1000y
Never put a group on paper of the above load before the match but it shot well.
I've got about 15 rounds left from the match so I'll seat them deeper in .010 inc & put those groups on paper.
The Vit N555 seemed to just get better as the charge went up. It was a Hot as hell at the match today & zero pressure signs.
If I don't wind up having to seat deeper I'll try stuffing in 38.9gr next & that's going to be compressed.
The 38.6 info above was 5 x over the magneto & first shot was with a cold clean bore.
First shot was a little slow, then it got happy.

I just broke my first barrel in today. Wow I'm sold.
Virgin alpha ocd brass, H4350 .060" jump berger 109 lrht
Sent 35, 35.5, 36, 36.5
All printed 3/4" and in 5 shot groups.
I didn't Chrono it, but confirming groups at 600y the dope lined up around 2850-2860 which is fine by me, maybe it will still speed up. Either way it was a very easy and fun day because everything shot well.
I'm just stoked I used my regular 6.5 creed mags and they fed perfect, plus I was easily able to stuff x15 of those guys in there with my 419 extension.

I'm loving the shit out of mine.
33.6 of Varget.
Alpha Brass (Virgin)
CCI 41's
105 Berger Hybrids jumping about 40
Running at 2885 fps out of a 26" Proof
I think she's sped up and settled down now. This is right about 250 or so rounds into the barrel.

Benchmark 26” 7.5t VCC (Strait Jacket)
Curtis vector
105 hybrid ~ .040 off touch. I eye balled it. I will remeasure for a .060 jump for remainder .
36.0 H4350
Cci #450
Virgin alpha OCD brass just .242 mandrel.
2900fps, 9sd, 21es…only the first 100 rounds through tube so I expect more speed over the next 50-150 rounds where I’ll really check numbers. It shot bug holes at 100 and dope was dead on out to 600.
Also planning on running the 109 for PRS. So I’ll get new numbers when barrel settles down. Planning on running it to 3000 for the 109.
damn it’s a heavy barrel contour. Definitely taking off some weights when I get it ready for matches.

You may wanna slow it down a little. Try and find something in the 2850-2950 range.
My 6creedy is rocking them at 3100 and it is a laser beam. Proof 7twist. No where near pressure in the VA heat. I think after it settles down and speeds up it will be a great barrel. Fast! Looking forward to testing another 100 rounds next week to get it broken in. My 6creeedy has got to be getting close to its end. It will be at 1400 rounds after Pigg this weekend.
For reference I run 36.0 h4350 in alpha brass and my 109's are going 2850 and it might speed up a little since I'm only at 100 rounds. That said, sounds like you have a fast barrel regardless
I agree. Benchmark makes fast barrels. I’m at 36.0 with 105 at 2900. Only 100 down tube. I can’t wait to see where I end up in a week or 2 after 200-250 through it.
Some data from today:
Hornady 2x brass, CCI 450, Berger 109 at ~.080 off (2.535ish OAL), Varget, 26" Bartlein with 400 rounds through it, 95 degrees outside.
33.2 - 2870
33.4 - 2892
33.6 - 2901
33.8 - 2921
34.0 - 2938
34.2 - 2962
33.8 was right in the middle of a nice steady POI and shot a 3 shot group (I know..) in the .2s. I'd say that's a wrap for load development.
Oh and no pressure signs for any of these loads despite the heat, which was nice.

I just typed a up a response and hit reply but don't see it here, so sorry if this double taps with a reworded post.
I was looking at the change in POI, which I thought was the idea behind an OCW test. The POI was the same for 33.6, 33.8 and 34.0. I also thought we didn't believe in velocity flat spots anymore?
I didn't write down the ES, but SDs were low single digits, 2-7fps, but only for three shots each, so take that for what its worth.
This is more just info, should someone want to load up some 109s with Varget.
Pick a speed. Forget "nodes." Shoot more, develop less.
Everyone has a different way of doing the same thing. If it works for you, then it works.
If it shoots 3/4" load dev for me stops and the practice and shooting begins 
. Which happened to be the case with this 6gt.... 36.0 h4350, let's try .060" off... Cool all rounds touching I'm done.
I don't shoot f-class, most targets average 2moa, we'll all be just fine blaming ourselves and not the load that isn't .1 "if I do my part".

I’ve heard this before. Was there any number of rounds attached to this cleaning recommendation?
edit by heard this before, some people are recommending this classic combination with 300nm after every 60ish rds, on the army’s new MRAD.
Seems aggressive.

I've been hearing good thing about the match burners, they are actually more readily available then the bergers
So with me not being able to find varget and wanting to save my h4350, I was able to grab some n140, has anyone messed with it?
I know it's popular with Dasher, and wanted to know if it's comparable? Anyone have a load?

Went out yesterday and fired off a few rounds.
I picked a charge weight in the middle of Hodgdon’s recommended load data and went with it.
24” Hawk Hill with 36g H4350 under a 107SMK yielded 2780.
7 rounds and an SD of 8.8.
This with virgin Hornady brass
Mirage was horrible but less than an inch at 100 yards.
Next up, a seating depth test, but this looks promising provided I can get ahold of more bullets.

Tried this basic load of h4350 34.5 grains and 107 SMK in two new rifles. Amazing not even worked up and shooting this good. Mirage was horrid, yet still good groups.
13 rounds though this Curtis. Bore sighted, three rounds to hone in on paper then two groups of 5
This Ruckus has 32 rounds through it now. Twenty the other day at a 100 yard indoor range, and 12 yesterday at 200 yards.
