It was a long, cold, snow winter and I decide it was time I learn to reload. Read several manuals cover to cover and watched so many Youtube videos on the subject I'm surprised I didn't get a visit from ATF. Most of my test loads seem to go together fine but I'm having issues with my 45-70 loads. Cases were prepped sized, primed and charged. I'm loading LaserCast 405gr and seating to 2.53" OAL which is just at the middle of the cannalure. That is the recommended OAL in the Oregon Trail Bullet Company manual. However, when I use the Lee Factory Crimp die it pushes the bullet down another .02" giving me an OAL of 2.51". I've tried resetting the die, seating the bullet a little shallower but nothing I do seems to matter. I took the FCD out of the press and bullets pass through without issue. I'm at a loss. Any of you seasoned professionals have any advise?
