6 BRA

thinking about getting a custom FL bushing die from widden thinking about using alpha brass i don't have none yet so don't know thickness of the neck area what bushing are people using. any info would be good .
 
I wouldn’t want to be locked into .0015 bullet hold, especially with a 6 BRA as most shoot better with .003- .005 of hold.
I would use Lapua brass and either a Wilson full length bushing die or Harrell’s #3 FL bushing type die with bushings 2-3-4 & .005 under a loaded round neck OD to test.

I use Alpha in the 6BRA, loaded rounds are .269. Bushing size .266. A .267 would likely be fine. If you have several 6mm's and use brass with different headstamps, best to have bushings down to about .265.

I'm using Alpha 6BRA brass and Berger 109g LR Hybrids. I'm sizing with a SAC die with a .267" bushing and a .240" mandrel. With the Alpha brass the .267 bushing is doing all the sizing and mandrel isn't really contributing anything. My finished brass is very consistent with Neck O.D. of .267" and Neck I.D. of .241 so I'm getting virtually no spring back even though I anneal my brass every time. Not sure if this is a good thing or bad thing. I'm thinking of going to a .265" bushing so that I'm working the brass a little harder and the Mandrel can do it's job. Feedback welcome, I'm always looking to learn from the experience of others. - G
