HI,
I've got 2 questions really.
I was out shooting some of my old unquenched WW loads and got 2-3 keyholes per 100 rounds fired. Now I know this is common if one is fire forming brass in wildcat cartages W/ undersized bullets (25/06 in a 7mm/06 wildcat), or if the rifling is too fast or slow for the bullet wt.
But why would i get only 2-3 keyholes out of 100 rounds.
2nd I noticed that after about 50 rounds the point of inpact started to rise &
kept rising slowly w/ each successive group. I guess it could be because of bore leading but accuray did not deteriate.
