It should be noted the the T/C barrels for 32 caliber cartridges have a .308" bore so my loading has been with .308" and .309" bullets.
I load a lot of .30 Carbine for my B'Hawk and in those loads, I use the Berry's Plated .30 Carb bullet exclusively.
These bullets are quite cost effective and very accurate -- and Berry's rates them to 1,900 FPS.
I can't use them in .327 Federal with a .312" bore, but if you need/want .308" slugs for your Contender, you might consider the Berry's plated RN's.
Great bullet, cheaper than any .30 Carbine specific bullet on the market.
