Yeah... I was going with needing the right projectiles to make a BP load effective, knowing that regular smokeless type projectiles probably won't have enough velocity to expand at the lower velocities and aren't heavy enough to make clean kills at any useful range.
Folks always seem to underestimate the hazards of just storing BP, much less making it .. smokeless powder is so much less regulated than BP because it is so much safer and reliable and predictable. Given what it costs to properly make good BP , smokeless powder is cheaper to buy , easier to store, and reliable for much much longer than BP on a pound for pound basis .. and you get many more loads per pound..
Do the math ,most modern cartridges cases can hold 30 grains , maybe 40 grains , at best less than 50 grains of BP .. While 30 grains of BP is a fair 44 cal pistol load , some pistols load up to 75 grains ( Walkers) .. 45-50 cal BP Rifles usually start at 75 grains and some go up to 150 grains.. That makes a modern rifle in a typical 30 cal cartridge, using about half the powder of a BP rifle, pistol loads really, and firing a pistol weight bullet .. 44 cal round ball is about 138-140 grain , get into conicals and you can see 180-200 grain bullets .. There is nothing magical happening here, you can't get blood from a turnip, you use BP pistol loads and BP pistols round ball bullet weights, regardless of bullet shape, .. you get BP pistol velocities and energies and range out of a modern rifle, not much more than that... and woe be unto those who try this on a rifle with a gas system.
if you want to go with BP , and all you are going to get out of a 30 modern rifle is BP pistol performance at best.. why not just get a BP pistol to start with.. really nice ones are fairly cheap. However, in SHTF situation, you have to ask yourself.. do I want my poistion revealed by clouds of powder smoke? well, do you ?
Couldn't resist a little Josie Wales when talking BP.
