    They fit great on bullet diameter of .311 after I flared the skirts of the gas checks, I used the base of a british 303 bullet.

  2. Rough Edges 3 Star Review

    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.

  3. Great bullets now 5 Star Review

    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.
