Yep, steel cases are throw-away.I never loaded 7.62X39
Cases of steel core were a little over a hundred bucks -- delivered.
My go-to general rifle is a Springfield 1903-A4 in 30-06 Ackley Improved - she keeps up with a .300 H&H in a short action ~ deadly accurate with 180gr partitian's & her Swarovski optics.
I reload all my center fire fodder except for scatter guns & the AR (she eats too quick + the bits and pieces are so small).
I have other specialty girls, .375 H&H for bear, a hot rod .270 mountain Whitworth for sheep & deer & even a 14" .375 JDJ contender.
Too many choices. : )
