[QUOTE="AZShooter, post: 1302389, member: 5219"] Lapua uses small primer pockets for one of their offerings in 308 Win as well. The BR cases use the small primer/pockets too. Many believe it can add to accuracy. If there was one issue it might be the use of these cartridges in very cold hunting conditions. Perhaps the small rifle magnum version would help. From Accurate shooter: [url=http://bulletin.accurateshooter.com/2013/05/large-vs-small-flash-holes-in-308-win-brass/]Large vs. Small Flash Holes in .308 Win Brass « Daily Bulletin[/url] "Tests by U.S. Palma Team members showed that the small-flash-hole .308 brass possibly delivers lower Extreme Spread (ES) and Standard Deviation (SD) with some bullet/powder/primer combinations. All things being equal, a lower ES should reduce vertical dispersion at long range." As for what size firing pin.....I built a 6 BR with a standard SA Rem 700 action. The cartridge uses CCI 450 small rifle magnum primers. The rifle is super accurate and has no issue with pierced primers. A friend also built a 6 BR with another SA model 700 and he also has no issues. [/QUOTE]
