I do. But I use them for my CZ Shadow 2 Orange that has been modified spring wise to shoot soft loads to help mitigate recoil.
I load them over 3.5 grains of N320 and seat them at 1.07 OAL. They shoot a little stiffer than a 5\” .22 LR 1911, accuracy is incredible and has to be seen to be believed. I have tried no less than 6 or 8 different powders with these and the N320 is by far the best.
Saw your post while I was ordering another 2k.
