Re: 7mm RUM
I have yet to try the triple shocks yet but I have loaded the regular 140 grain XBT bullets with 87 grains IMR 7828 a CCI BR2 primer and had good results ( just under half inch groups ) and also same powder charge with a federal 215 primer and the groups opened up to 3/4 inch. They perform great on game with great one shot quick kills. I hear the triple shocks shoot tighter than the XBT also. I have used the 140 accubond and got decent accuracy with 90.5 grains H1000 and CCI 250 primers. didn't get a chance to try them an whitetail though.
Guns and ammo, what more do we need?
