First test a couple of weeks ago gave really nice group, but it was a bit low.. Today I shot 96p and 94p targets.
Maybe it is in my head, but I have shot cast projectiles during same training sessions. H&N balls just seem to group better.
I measured that my own mould drops dia. .3294" balls (averange of 10 measured) vs H&N balls are .3331"
There is also small difference in weight. Is this difference big enough to be significant?
I used lead sheets I bought from local scrap yard to cast these balls. Are H&N balls pure lead or some kind of alloy?
If alloy, how hard is it?
