It's really not necessary for the paper to enter the bore when chambering a round. The leading edge of the paper right to the end of the throat works just fine. Some folks have burned up a ton of band width going on about how you shouldn't seat the bullet over .1 into the case... Problem is if you look at a factory loaded round from back in the day those rounds were seated really deep. Folks that shoot groove diameter patched bullets seat those just as deep as a grease groove.
