New 6BR coming

[PopCharlie]

I have a new 6br in the works. It should be done soon. It will be a short range gun primarily. It is based on a Defiance Rebel action, Bartlien 8 twist barrel, Macmillan stock. The chamber will have a .266 neck with a .060 free bore. I plan to shoot 95 gr BIB FB bullets. I'm looking for powder/primer suggestions. I have n135, n140, n150, and re15, ( I have Benchmark and IMR 8208 XBR, too, but these might be too fast). I have a small amount of h4895 and Varget, but no enough to develop loads. This is my second 6br, the first one was a Cooper Varminter with a 14 twist barrel. It loved Berger column bullets, seated to touch, with n135 and br-4 primers. I figured I'd start with n140 and br-4s. I have new Lapua brass with necks turned to .010. I made a couple of dummy rounds using leftover bullets to make sure this would work. Necks with seated bullets measure .263.
Any load suggestions would be appreciated.

Thanks

My first 6br, I was shooting the Sierra 95g mk and IMR4166
Shot small

App. 29.5 gr. of N-140 will be your friend with the 95 gr. Shot well in my 1 -8 Tw.

I agree start with the 140 but if you shoot anything lighter be sure to try the 135 as it will really shine as well

A little more deck clearance wouldn't hurt. We have found that .003 is minimum and most times .004 is better. Matt

I've shot a LOT of 95gr bullets from a 9tw 6BR using 8208 in competition. While 8208 was the load I used most, I found 140, 4895, 4166, and even 4064 worked well with it too. If you have other primers to try like 450's or 205GM they sometimes will work better than BR4's. JME.WD

Edit: Add Reloader 15 to that powder list. Won several matches with that powder when I first started out.

I have 450s, and 205ms. I will try all 3.

Thanks for reminding me Roger. I dunno how I forgot Re15, that's what we started with. Yes, add R15 to the list in my previous post and I'll edit it too. WD

9 years shooting my 14 tw Kreiger 6br. The 60 gr Sierra Varminter with 33.3 gr of 8208 is by far the most accuracte load I have tried and it has good fps. Varget and R15 decent groups about 100 fps slower. H322 pretty good for accuracy and speed. V133 and Ad2230 slow speed not real accurate. I'm sure Itested a few other powders. Don't like VIT and Norma they are too expensive. It's a modified Rem 700 Varmint barrel. I shot one group in the ones and .25" goups a common. I assume any groups much over .350" are my fault, wind or they are mass produced hunting bullets.

I have a 1:10 twist 28" Krieger 6BR barrel. Using Randy's 95 BIBs I compared Varget, RE-15, and RE-17 about 10 years ago. Laupa brass and Wolft SMR primers. Varget gave the poorest vertical at 300 yds. RE-15 has a sweet spot at lower velocities, aroung 30.2 grs at 3005 fps. RE-17 shined at high end. 34.4 gr gave me an average of 3110 fps. I was getting les than a 0.5" vertical at 300 yards. Sadly, my new 1:8 twist barrel came in and switch over to that with the 105/107s and haven't had the 1:10 back on. I also haven't seen RE-17 on the shelf in some time. Not even sure if Alliant since makes that powder.

Randy makes a great bullet and I think that is a 300-600 yard killer bullet.

RE-17 is still made:

I always figured that was too slow for 6BR. Learn something every day...
