Forming 243 40' Improved

[Catfish]

First I NEVER Annel cases to fire form them. RL-22 is a little slow for the 100 gr. bullet in the .243, but I would have guessed it should have fire formed them. You only problem is that you are just alittle low on presure. If you can get in more powder put it in, if not you`ll have to change powders.
