OK I'm out of ideas. I cast a bunch of bullets for the '03-A3 using a mould I've had for years and never actually used until now (am I the only old bird who does that?): Lyman's 311291. Cast in #2 alloy they come in at 173 gr which is close enough I guess to the advertised 170 gr. This is a gas check design and when I mic the shank (which is tapered) I get .290-.292 inch at the narrow (bottom) end. I have two ancient boxes of Lyman gas checks, marked for .30 cal and .32. The 32's are too big and the 30's too small-- they go on crooked. I'm guessing these are the old style Lyman checks that just slip on and do not crimp.
The only idea I've had is to open the smaller checks a bit with a tapered punch so they'll go on straight. What am I doing wrong? (I'm a newbie with these little copper doohickies.)
