Quick one; What bullet heel size suits bertram 310 cadet brass?
From memory the HRC/Black Widow bullets are no good, designed for thinner Super brass so even if you flare and press them into Bertram cases they typically wont chamber easily. Boyne cast and sell bullets I think are on the money, they have a .308 heel size.
Just want to know what fits Bertram cases;
Rifle is a BSA if that matters.
