Trying to load some cast bullets in 7.62x54r.
Got some aluminum gas checks.
They seem to go on crooked & takes quite a bit of oomph to get em on straight.
Sizing seems to work well in crimping the gas check.
Are they supposed to go on with some difficulty?
Even with that, 2 of the gas checks fell off when I re-tumble lubed 'em.
This is my very first experience with gas checks.
But I've been reloading for about 6 years - 10,000 - 12,000 per year.
Mold is Lee CTL-312-160-2R
Sized .311
