I clocked them with a chronograph,I also hand load handgun ammo. I don't have any of the info from my tests (got thrown away buy accident). I didn't try any of the ones you asked about. I did try one heavy bullet, 375gr. Buffalo Bullet, this is just what I think I remember about the vel.---- 110grs. BM3, about 1900fps out of my Omega. When the weather clears up I will try it again and report my findings. I remember it was always faster than 777 with equal weights of powder and bullet. I am going to try weighing some charges and see if that helps the spread. GOOD HUNTING
