Re. Sharps4590 comments about going back to the original caliber,this is actually a good option. As many cadets as have been rebarreled, there should be plenty of good original barrels avaliable.I have a lot of fun with my .310.There is a bullet mold avaliable now for a proper heeled bullet,dies are avaliable, and 32-20 cases can be shortened and used for cases(some rifles require the rims of 32-20 cases to be thinned and/or reduced in dia).The proper heeled bullets(.323") are much better than 32-20 bullets(.311-.312").If a 30-30 case is used and blown out pretty straight(ie 35/30-30), don't grind the top of the breech block, turn the rim to smaller diameter instead.
