The original PO wrote. "Ive shot 100 grains BH209 and decided this is going to be the year I drop charge down to 80 grains. I've found 100 grains is a bit overkill for plain ole deer here in Tennessee. Anyone using sub 100 grain loads? 100 grain loads in my Accura MR recoil like a 3.5" magnum turkey load. It gets a bit ridiculous."
In response; Novashooter "wrote I think one reason muzzleloaders tend to startle people can be the muzzle blast. By numbers alone a 50 caliber muzzleloader is not comparable to a 3 1/2" turkey load at all. If both 7.5 pound guns, the muzzleloader, assuming 1950 fps, 265 gr projectile (includes sabot), and 100gr powder, makes 43.7 ftlb of recoil. The 12 gauge assuming 1200 fps, 950 gr projectile (includes wad and buffer), 32 gr powder produces 71.5 ftlb of recoil."
My response was to the original PO comparing the felt recoil in his opinion being similar to or greater than the recoil of a 3.5 inch magnum turkey load. This was not a by the numbers comparison but is a subjective observation. There would be differences even in Empirical Statistics. How do you account for wearing a T shirt versus a heavy jacket on recoil? How about a thin recoil pad versus a heavy one or a heavy load versus a light? There are two many variables that the "numbers" do not into consideration. But even if they did the comments were made subjectively. I value all opinions and just wanted to clarify my comments.
