One of my R\C's has a slightly worn bore and I've been experimenting with different loads. I have found that it sprays milsurp everywhere. No groups at all, just patterns. It does the same thing with the Hornady 150 SP's which my favorite K98 loves (It has a tight bore and crown though). It will, however, group the Hornady 195 SP. The last two times I've shot this round I received sub three inch groups. After comparing this bullet with the 150 and milsurp FMJ's I've noticed that there is more mass from base to where the bullet tapers than the the other two and thus my theory is that more bullet is actually grabbing what rifling is left in the bore. I would like to try the Hornady 170 grain RN since it has even more mass than the 195 over the length of the bullet. But before I slap down $25 I'd like to know if the Round Nose is going to cause a chambering problem. I believe I heard along time ago that some K98 owners had this problem. Any experience with this?
