Have been playing about with some 180grn round nose in my 30-06 the bullets are pro-hunter with 56.5gns of H4350 behind them.
The problem is the Hogden manual says the COL should be 3.3inches which only leaves me with .221 of the bullet in the case will this cause a problem.
I also checked the length of the chamber at the same time and even with rounds at this length I still have 105 thou to the lands which seems a lot.
There does not look to be a lot of wear to the throat of the rifling but it is a BSA and was made in 1956 ish.
With factory 150grn it will shoot 1 1/2 groups at 100yds.
