Nice shooting!
I have found my magnetospeed works best with cast bullets when sensitivity is adjusted to «Hi 1» (I think it is called).

I have a V3 and use "Custom" and level "6" for all my cast shooting from 900 to 3000 fps and .22 to .45 caliber.

I used custom, most all sens. numbers. No worky. IMHO, several other problems, big one is mounting and barrel/blade harmonics. Or it could just be the one I have. Who knows. I'll set up the optical for now - PITA but dependable.
I can go to 17gr of H110 or 4227 to test, see where the alloy fails. Deprimed the yesterday cases, primer pockets still good. 16 of H110 gave 2150 optical for the PB, I'll try 16.5 & 17 next of this GCd. If fail I can up Sb to 2%. Not sure where I'll end (stop) 2400 with 145gr AR 15 vs 2400 168 AR10? Sure will be lighter. Should be good for hogs @ 200.
JW, ever get your MS. to work?

Shot at 100 today, 15.7 Rx7 was the best, probably 17-1800 fps. 16.5 W296 wasn't bad, mostly horizontal @ 2200 or so fps. Not sure what caused this funny looking group - maybe me? Alloy fails after that but it is only 1% Sb. So toss some super hard in the mix.

Shot the lite loads in the BO pistol today, barely noticable recoil but no cycle. Accuracy is fine @ 50 (2 shots 3/8" c-c). Sighted the scope @100 leaning on the back of the 4 wheeler with 150gr. G.D, bout an inch high @ 50 today, probably difference is foreend on stand. Funny, 110gr with 9 gr cfe pistol almost cycles, but 4227 and cfeblk don't. Slower powder and heavier bullets should have gotten the pressure up. Thought I had the 2400 load with me but nope. Try them later and try the 170gr PB too. Trying for 357 sig performance with light recoil.
