She does? - Hmmmm - smokeless powder loads producing identical speeds with the same projectiles kick about 1/2 of BP loads - that is how they feel. The actual is probably about 1/3rd less. My 12 bore double's regulation was identical for heavy BP or equivalent smokeless loads, even though the black powder loads had so much more recoil. I might have been just lucky. Seems to me the heavier recoling load should have diverged.
