[QUOTE="BountyHunter, post: 24039, member: 12"] Cybra, On the 6mm BR, I am building a 6mm BRH now (shoulder moved forward .200 and 45 degree shoulder and .265 neck). This design is similar to the popular 6mm BS (Baby Shehane). It will be used with 95-105 VLDs from JLK in a 28" HV taper Spencer barrel with 1-8 twist. My plan is to be .0005-.0007 per side with Lapua brass. Good 600 yd BR gun, egg shoot and backup LG. Dave Kiff made the reamer. My 1000 yd guns I set up to have .001 or less on each side. Intersting side note on clearance. Some of the early top dog LR BR shooters shot magnums with .003 clearance on each side as they thought that was best way to shoot magnums and consistently won. Now the same guys are using standard BR clearances of .001 and group sizes has shrunk by 50% on average at least. 2-3 years ago, you could win IBS LG with a 6" group consistently, now it takes 3-4". HG would win with 9-10" now you must shoot 4-6" Personal opinion is that tight neck turned cases are more uniform, give more uniform release, MV, SD, ES etc. The LR BR shooters have found that we can control the tolerances as tight as the shortrange BR shooters with good tools, loading techniques and cleaning. Look at the results at the last nationals on group sizes for both LG and HG. Quality tools and procedures such as K & M neck turner are key. I have tried all of them and his is the absolute best (in my opinion). You can turn to .00002 precisely. His tools are a top choice for BR shooters. Good luck BH [/QUOTE]
