Ah. If they gave that rifle to me, I'd craft some mousefart/gallery loads.
I do shoot 8mm, .30-06, 303 Brit, 7.7 Arisaka and others with a steel butt plate ... and one of those LIMBSAVERS ... and sometimes my jacket wadded up underneath, too.
AA
8mm Mauser or 8mm Remington? The 8mm Mauser isnt bad, but the big remmy can be.
I've shot a .270 Browning BBR more than anything and my father gave my brother in law a Browning B78 in 30-06 when I moved to Alberta in 1982. Falling block, 26" hexagon barrel. I still have the little brother in .22-250. Both will shoot, but every time I pulled the trigger on that '06 the Monte Carlo stock slapped me right in the face lol. Beautiful rifles though.
When I was load testing my Sako TRG-S .338 Lapua with the 230 grain Fail Safe and Sierra 250 grain Game Kings I made a shoulder pad from 1/2" high density foam, folded in half and duct taped together. The recoil from the Fail Safe load was so violent, it ripped that pad through the top layer on the 3rd shot from the bench.
I developed 3 loads for that rifle. A 200 grain Nosler Ballistic Tip at 3500fps. The 230 grain Winchester Fail Safe at 3150fps and the 250 grain Sierra at 3030.
The 350lb Black Bear I shot at 40 yards with the Ballistic Tip was suitably impressed. 4" entrance that broke 4 ribs and failed to exit. Lungs and heart were jello.
