Just started reloading for a 300 wm. First thing I noticed was was the short neck for caliber. All my previous reloading has been for 308 0r 30-06 based cartage cases. My question is will I have sufficient neck tension without putting a crimp on the bullet? Just developing loads so starting with IMR 4831 and H4350. 208 eld M, Sig cases,Win large mag primers. These powders are what I have on hand. i'm not worried about extreme velocity as 800 to 900 yards is the farthest I anticipating shooting. Thanks for any help. If you don't reload I do not what to hear your theories.
