I just loaded up a bunch of 22-250's with 30.5 grains of IMR 4895 and hornady 55 grain SP's, and I was wondering if any of you ever go this low with powder charge? My gun seems to shoot them well and the recoil is nill, and I would bet a barrel would last much longer at this level as well...? However, I dont have a chronograph and was wondering how slow these things are moving? Ever go this low???
