6mm BR Issue

[Henryrifle]

I really relate to this thread and I really appreciate many of the comments posted here but, the ones by @LHSmith ring true with me.

Have been shooting F-Class (F-T/R) for the past three years and at the same time the sport/hobby can be very rewarding incredibly frustrating.

I like to shoot for fun too and we all appreciate a very small group. I think you not only need great equipment to consistently shoot small but you also need meticulous brass and cartridge preparation. If that weren't enough some unknown ratio of skill and luck are required too.

There are guys who can just flat out shoot. I have met them and shot with and against them. I am not one of them. If you are one of them I know you are thinking that I am just wrong about what I wrote above. I know that not everyone or maybe no-one will agree with the above but there are times when I know I did EVERYTHING right and still shot a .6.

Today was one of those days. I just know [hope] tomorrow will be better! It's what makes this fun right?

Guys. I have a 6mm BR that currently has 220 rounds thru it. I have worked up loads with both the 110gr. Hornady A-Tip and the Berger 109 gr. Hybrid Target. I’m using Lapua brass with the necks turned to 0.125 which cleaned up about 85% of the necks. I have loads worked up with Varget and H4895 which will both shoot groups in the 2’s. My problem is that every load that will shoot this well will put 4 rounds into a 0.2” or 0.25” group and then throw one round out that increases the group to 0.40 or 0.50. It’s never the same shot but it seems to be consistent at throwing one round out of the group. It could just be my shooting, lol, but even a blind hog finds an acorn on occasion so I believe its an ammo or rifle issue. The rifle is a Rem 700 action with a Preferred Remage barrel in a laminated stock that has been pillar bedded. I haven’t bedded the recoil lug yet but I just don’t think that’s going to cure these flyers. I checked the Varget load and it was running an SD of 6 so I don’t think it‘s a powder problem. Any suggestions on what to try next to remove these flyers would be appreciated.

According to your description your rifle has not been bedded.....period. I am surprised that you have not noticed with all of the pictures of good bedding jobs that are on the internet that NO ONE omits the lug. On that same subject, you cannot fully evaluate the quality of a bedding job just by eye. I don't know if it is still available, but Alex Wheeler once made a video on how he checks bedding with a dial indicator. I first heard of this, years back, from something that Mike Bryant wrote on a forum. It really caught my attention. IMO working on loads without perfect bedding is a waste of time, barrel, and components. Bedding can make a huge difference, and there is no way around it.

I had a flier issue that drove me nuts. Finally figured out that the bolt handle was contacting the stock. Added clearance and problem solved. Not saying this is the issue with your rifle but it’s worth a look-see.

Have an old Savage rifle, re-barreled with a 6MM BR Shilen, 8 twist. Tried a variety of bullets and settled on 108 Gr Hornady eld-m and Berger 109. At 100 yards, the Berger 109s group better (3s, occasional 2s) than the Hornady 108 (4s and occasional 3s). 1000 yards is were we see a real difference. My wife and I shoot in Global Benchrest Association matches. We are not serious competetors, mostly compete for fun (you know, $400 Savage against $10,000 custom light guns. Match days consist of 2 matches. My wife shoots the Savage. She shoots the Hornady eld-m in the first match and the Berger 109s in the second match (still trying to determint the best bullet). Surprisingly, the Hornady 108 outshoots the Berger 109 at 1000 yards, consistantly (at 100 yards, results opposite). I believe the 8 twist is giving the Berger 109 marginal stability that doesn't show up at 100 yards. In one match, my wife actually won her relay, with a 5 inch group (beating the $10,000 rifles, made me smile) with the Hornady 108 eld-m. Best 1000 yard group ever with the Berger 109's was 7.5 inches, which I believe may go back to bullet stability. Might need a 7 twist for the Berger 109s.

What is your barrel twist? Could your issue be marginal bullet stability?

Barrel is a 1:7 twist
