Re: HELP WITH 6,5-284 BUSHINGS
my 6.5x284 has a tight (.291" neck), so I have to turn, however I seem to recall my last lot of virgin Lapua brass measured around .294" before I started working on it.
For my chamber, I turned the cases to .287". A loaded round measures .289" so I use a .288" bushing, which gives me a nice snug fitting bullet. I tried .287" and .286" bushings (as per the recommended 2-3thou less) and found that with these, I had a pronounced bulge beneath the base of the bullet when seated - my throat is quite long to accomodate 140 grainers to seat them just within, the neck, no deeper.
I would purchase a few different bushings and experiment as per previous posts.
