long range load for the standard 6mm BR

[BJ44BJ]

Here are a few pictures of my new project. A lawton 7500 RBLP action. A kreiger 1 in 8.5 twist. A Robertson Compsites Speedy BRX stock. A jewel 1.5 oz trigger and a Weaver t-36. This was chambered with a standard 6mm BR reamer made by Dave Kiff. Mike Bryant did the chambering.

I finally have my 6 br project together and will soon start load development. I have a berger 105 gr. Seirra 107 gr. and lapua scenar 105 bullets on the shelf. Can you guys give me any ideas as to a good 600 yard loads in your guns? I have been shooting mostly flat base bullets out of a 12 twist shilen barrel and have had spectacular results. I hope I will be able to find a good load for this barrel as well. Thanks

29.5-31.5,MAX!)gns of R15 or varget with the 105/107 is a good place to be...

I run 30.2-30.8 of R15 depending on temps.

Very, very nice rifle. You should get good results with all three bullets. If your barrel is a .236 I'd suggest starting with the Scenars at 28.5 Varget or 29.0 Reloader 15. You'll probably end up around 30.2-30.5 of Varget, maybe a little more of RL15. Put the Scenars or Bergers 010-.015" into the lands,distance past first contact). With the 107s I'd try both jumping and jamming. Reduce your load .3 grains initially if you seat .015-.020" away from lands.

I'm using 31.0 grains N540 CCI 450 .015 into the lands.
