These checks had very rough edges and I had to open them up with the end of a center punch before they would fit on the bullet base. After installation, they crimped fine.

These plain base gas checks are the coolest things since metallic cartridge cases. Getting them on requires a bit of TLC since they are thin and the bullets weren't designed for them. But the results are amazing. No lead on the bore even when pushed hard. Velocity I never dreamed of AND good accuracy. I had a whole bunch of .309 LFN 165gr bullets for 30-30 with plain flat base. These go on nice and I can shoot them up to 1800fps with no problems.
