Hello everyone. New to forum and new to reloading rifle. I have loaded many thousand of handgun rounds, but recently decided to have a go at reloading 223. I began on an old Lyman Spartan T press and a few months ago decided to move up to a Dillon XL650. It is really an amazing press. I read up and educated myself as to the steps involved in reloading rifle. (I have actually had most everything I've needed for a while, I just recently decided to start when I got the Dillon.) But I haven't come across anything to explain this. Since I am just reloading plinking rounds for the range (AR-15 & .223 pistol) they do not need to be competition grade. I will be purchasing either a co-ax or rock chucker supreme single stage press later this year for more precise 223, 30-06 & 308. But back to the problem: Brand new Lyman 223 dies and my 1st attempt...stuck case (lubed with Dillon case lube). It was not my first stuck case ever...so drilled, tapped and backed out cartridge as usual. Attempt 2: used RCBS case lube on a lube pad this time and deprimed and sized a few only to have them come out like most of the metal on the neck was scraped off? I don't feel they are safe to go onto next step. Anybody know what's going on? I mean...I'd hate to think its the dies...they are brand new. (it is depriming.) The different lengths of neck shaving (in the pictures) was because I tried adjusting the height of the die. Ideas? Suggestions? Answers?
PS... Thanks in advance for help!
