I will do my best to accommodate any neck dimensions. For more information, please contact Amy Bruno Parosky (at Bruno’s) Paul Parosky comments on this Neck-Turning setup: “For neck-turning, I use an old drill press that’s been re-worked. To avoid any runout, the cutter and spindle must be indicated before neck-turning. The RPM is approximately 520. My lube is a mix of mystery and royal oil. “Why the 30 BR dominates 100/200 Benchrest to Score Competition
Along with some wildcat variations, the 30BR is still the dominant cartridge in short range (100/200), benchrest-forscore competition. The 30BR’s.308-diameter bullets weigh more than the 6mm bullets used in the 6PPC (which rules group BR). The larger 30-Cal diameter is better at touching scoring rings. The 30BR is also easier to tune and has a significantly longer barrel life than smaller-caliber benchrest cartridges. You can find more information in our AccurateShooter 30-BR Cartridge Guide. Cases are expanded and then neck-turned
Parosky uses a series expander mandrels to produce his 30BR brass. Parosky then uses a modified drill press to neck-turn with power. Paul tells us that he uses three tapered expander mandrels to neck-turn the machine to the correct neck chamber. Then, he runs them through an FL expander mandrel, to ensure straight necks. The cases are then cleaned. Paul Parosky can also neck-turn 6PPC brass. This is a Paul Parosky post from the USA Benchrest & Extreme Precision Shooters facebook page. It illustrates his 6PPC neck-turning operation.
