i am cursed when it comes to reloading for any ar 15 . my rcbs resizing and depriming die is messed up i keep getting crooked necks . i had to use a old die somone gave me awhile back to get by because i needed the bullets to varmit hunt with thursday . the die im using made the cases to long so i had to trim them with a trimmer that had a broken handle because the handle for my rcbs trimmer has dissappeared. it took me about 3 hours to make 28 223s. the 69 gr noslers group great for me with 26 grains of varget . i always have hell workn with 223.
