Was really bored the other day and decided to try some different powder in my 32ms I tried 300mp, Lilgun and 4227 and the 4227 was almost 3/4 full in the case but oh man did it shoot.  Roll Eyes I usually use AA9 like everyone else, maybe I'll try in the next match coming up.
Anyone tried 4227 in the short cases?

Nope, never tried it Van. How many grains did you use and what weight bullet?

13.2 WSR primers, Accurate Mold 32-210b, Dell 59c lube breech seated .050 with floral foam pushed down on powder.

right at 2 1/2 inches @ 200 not bad for a stumble on load, could do a little bit of fine tuning may be a good one.

Early on in small case development Dean Miller and Charlie Dell calculated the size of the cases needed based on a good fill with 4227. Both found that it gave indifferent to poor performance. Charlie went back to a larger base case with the 33 KR. Dean switched to Accurate #9S. When Dean reported the results he was getting Charlie went back and tried it and it gave good results for him also. Charlie went on to finally settle on Accurate #7 most of us used #9 or H 108 which gave identical results.
