The only issue, aside from cleaning, that black powder loads introduce over RST low pressure smokless is increased recoil effect on old stocks.
Sufficient lube keeps fouling soft for many shots. We shoot BP trap using cartridge blocks so we can put a dab of Crisco lube on the mouth of each cartridge.
I don't understand that statement Saskbooknut. If a load of smokeless, RST or otherwise, with the same shot payload, leaves the muzzle at the same speed as the blackpowder load, the recoil will be the same. The only possible difference could be the weight of the gases, which is negligible.
