Long ago I was working on a Subsonic Jacketed load for my 45-70. I was shooting Hornady DGS 500 grain bullets set really deep to function from the marlin action. A developed a trail boss load that was hitting about 900 FPS from my BFR (10 inch 45-70 revolver) but only getting about 700 FPS from my marlin. That told be the bullet was slowing down. These bullets are jacketed and very long so they have a lot of drag. I feel I am lucky I did not stick on in the barrel.

I would rather take a round of 50BMG to the foot than a 22short to the base of the skull. all 26 of my guns are 45/70 govt, 357 mag, 22 or 12 ga... I believe in keeping it simple. Wish my wife did as well...
