Sizing problem

[Proneshooter1]

Cast some Lyman 225462 to try in a 222 and 223. Bullets cast nicely and all was good until I started running them through the LubriSizers and things went weird. Had an unopened can (yea it’s old ) of Hornady gas checks. Checks fit fine on the base of the bullet but about one half of the bullet length into the sizing die it got hard to push further without mangling the bullet nose really bad. So after tearing the die apart and giving it a good cleaning tried again, same result. Broke out a new box of Hornady GCs, they worked perfectly as did some old Lyman GCs. I measured the old Hornady GCs and they were .228 in diameter where all the others were around.223, no wonder the didn’t work, I was trying to size the checks .005.
I suppose these were meant for a Savage 22 Hipower. They take a .228 bullet. If anyone needs these please let me know.

Gas checks are made for calibers. Its hard to make a general purpose check for all bullet molds. Plus variations caused by our alloy. So a perfectly fitting checks isnt expected. Its good to have a gas check expander die and gas check seater die.

To compensate for that they use material thicknes. The difference between my 6.5 checks and 270 checks is only material thicknes. I can actuall use the 270 checks on the 6.5. But its too thin to go the other way

Its why some swaer by annealing gas checks. Easier to seat and size. Its also why a lot of us get into making our own checks. Save a few cents and my checks thay fit perfectly and easy to size.

I have never heard of GCs specifically for the Savage 22 HiPower.
