Great 30 BR Brass from Parosky — Formed and Neck-Turned

Editor — Thu, 02 Oct 2025 14:23:01 +0000

Here’s good news for 30 BR shooters. Paul Parosky, maker of the excellent PRP Custom Bullets, is now offering 30 BR neck-turned brass. This can save you considerable time and effort forming 30 BR cases from Lapua 6mmBR brass. And the neck-turning is superb, again representing time savings (and no tools to buy). You can order this 30 BR brass from PRPbullets.com. If you communicate with the PRP team, Paul may be able to neck-turn to your specific thickness. Paul notes: “Here are necks turned for a 0.330 neck. I’ll try my best to accommodate anyone’s neck dimensions as they wish. Just contact us through our website PRPBullets.com.”

About this Neck-Turning set-up — Paul Parosky notes: “For neck-turning I’m using an old drill press that has been re-worked. The cutter and spindle are all indicated before neck turning to ensure no runout. The RPM is around 520. The lube I use is a mixture of royal and mystery oil.”

Why the 30 BR Dominates 100/200 Benchrest for Score Competition
The 30BR, along with some wildcat variants, remains the dominant cartridge in short-range (100/200) benchrest-for-score competition. The 30BR’s .308″-diameter bullets are larger than the 6mm bullets used by the 6PPC (which rules group BR competition). The bigger 30-Cal diameter has an advantage in touching scoring rings. In addition, the 30 BR is also relatively easy to tune, and barrel life is considerably better than with smaller-caliber benchrest cartridges. For more information, see our AccurateShooter 30 BR Cartridge Guide.

Cases are Expanded, Then Neck-Turned
To produce his 30 BR brass, Parosky first uses a series of expander mandrels. Then he neck-turns with power using a converted drill press. Paul tells us: “This is done the old school way, I use three different tapered expander mandrels, then neck-turn it to the proper neck chamber, then run them up through a FL expander mandrel to ensure necks are straight. Then I clean all the cases.”

Paul Parosky Can Also Neck-Turn 6PPC Brass

Paul Parosky also expands and neck-turns 6PPC cases that are made from parent Lapua .220 Russian cartridge brass. Here, illustrating his 6PPC neck-turning operation, is a Paul Parosky post on the USA Benchrest & Extreme Precision Shooters Facebook page.
