I shoot a TC Contender in 30/40 Krag. It shoots 173 grain, .310 diameter gas check bullets very well when driven by a 18.5 grain load of 2400.
Owing to pricing, I recently bought 1000 Lasercast, 173 grain, .310 bullets. The bullets have a gas check location but no gas check.
The question I have is, is there any way to install gas checks without a sizer? I don't know anything about making cast bullets, just shooting them.
I would appreciate some help. Thanks.
