I am trying some Nosler 55gr Varmageddon for my Savage 223 and am not sure how far to seat them. I have been shooting 68 gr Hornady BTHP and 69 SMK up until this point and have loaded them from .005 to .020 from the lands. When loading these 55gr at .020 from the lands there isn't much bullet in the case neck and they are very long which is no big deal. Should I seat them a little deeper or just go shoot them? Also, if anyone has any tricks to load flat base bullets please help me out because I've dumped 2 loads all over my table now and am hoping I get the others in there straight. Thanks in advance!
