The big risk of loading up ammo for heavy barrels and espsially in ,30 caliber is that the gaspreasure gets bloody high.
The lower the bulletweight the higher must the gaspreasure be to archive the high recoil needed for recoiling back the heavy barrels.
So if wanting to reloading highrecoilrounds for stiff guns I belive that the best would be to use as heavy bullets as possible cause there will not the gaspreasure be as high, and this will as i see it save the guns.
