I just ran some 200gr Hornadys over the chronograph, not a screamer load, but very accurate and comfortable to shoot.
65gr of Reloader 19, lit with a 210 Federal primer, for 2423fps. Std. deviation of 13fps, for 10 shots.
This was from a 24" Browning 71.
I'll try some factory loads and maybe a couple of others next time out.
