Hello again guys. Time for the reloading newbie to beg for more help.
Anyways, I have been trying to reload 300 win mag now. When I try to seat the bullet, I am getting ALOT of resistance, and it feels like the bullet is getting stuck in there. This only happens with 180 grain bullets. I use some 150 grain with cannelure just to find seating depth and these bullets seat fine and feel fine when seating. However, whenever I try to use the 180 grain bullets, its back to stuck. I thought maybe because the 180s were longer that it was pushing up against the powder, but it does the same with empty cases as well. The 180 grain bullets seat fine in a 30 06 case but have the problem in the 300 win mag. What could the problem be? I am using 180 nosler partitions and ballistic tips and the 150s that work fine are hornady gmx. I use all hornady equipment. I tore the die apart and everything looks fine. Thanks for the help!
