Thread: 303 group-bad bedding?

Have you had the barrel slugged? I have done some and I know others who have done it or had it done none I have heard of are even close to .312"
most are .314" up to .317" my cast bullets are .314" with the nose .305", go for the heavier bullets they fit into the throat better the original bullet
was a paper patched 215 gr RN later changed to a 215 gr RN FMJ finishing up with the 174 gr MKV11 the throat is still the same as the 215gr bullets
lighter bullets like the 150 gr are way to short, Norma made a 215 gr RN soft point back in the day they shot extremely well and killed deer on the spot
Hornady's 174 gr RN was nearly has good pity they are discontinued
