no problem at all getting .20 sec splits, on 10" circle at 10ft, with a lw Commander, using my 460 loads. I know you are math-challenged, but TRY multiplying the bullet wt, in grs, times the velocity in fps, and toss out the irrelevant zeroes. 70grs x2300 fps is the same as 230 grs x 700 fps, in that equation. What doesn't show, tho is that you need about 10 grs more powder to get the 2300 fps, and at least SOME of that powder has to be calculated as "ejecta", for purposes of calculatiing recoil So 70 grs at 2300 fps recoils like 230 grs at 780 or so fps. About like commercial Winchester 230 gr ball in a lw Commander.
Unlike you, I am aware that a LOT of missing of the chest gets done at 10 ft,when it's for REAL, and that 10 ft covers nearly 90% of the justifiable civilian defensive SHOOTING. Since 90% of all attacks dont REQUIRE hitting ANYBODY with a bullet,(if you get the gun out and VISIBLE to the attacker,in time) we are talking about 10 ft covering 99% of all attacks. ]
timed from the first shot, .20 second means 6 hits in 1 second. such a load and gun CAN get 7 hits per second, too, but it takes a guy who REALLY works at it a lot.
I don't trust Mexican 'quality control", and that load aint very hot at all,in a .45 ACP. It aint AP, and doesn't have but about 2/3rds of the energy of my 460 load.
What wheel do you "think" I'm "reinventing", hmm? WHAT 28 oz, 7.8" gun had a load that offered .45 ACP type recoil, AP performance, and 800 ft lbs, hmm? You are talking out of your ass.
