Your comments regarding Beagling mirror my thoughts/experience exactly. I used this method for quite a while on the molds that I use for the K-98 7.62mm.
While the rifle would shoot some fine groups with these bullets from a Beagled mould, the consistancy was not there. Plus, keeping some type of shims in the same place on the inside of the blocks got to be a challenge. Believe me, I tried everything and finally gave up. figured that there had to be a better way.
The lapping method has so far proven to work well for me. And it's permanent. One qualification that needs to be present in the mould at the outset, is that the nose of the bullet must reasonably fit the bore because I have been unsuccessful in attempting to enlarge the nose of the bullet consistantly by lapping.
The first problem that I found with this it that it was nearly impossible to evenly embed lapping compound all the way up and around the ogive of a bore rider. Because of this, due to the distribution of the compound while lapping, the nose would be enlarged more on one side of the ogive that the other. I'm talking very very little, but enough to see that it was happening. Didn't like it.
So,deciding to give up on that, the technique that I use just laps the outside of the driving bands only, nothing else and has proven to make the groups more consistant and repeatable for me.
Anyway, just trying to decide whether to post here or attempt a piece for the Fouling Shot.
