I did a ladder test the other week and i settled on 44.5 gr Varget, Winchester brass, cci br2 and 178 Hornady HPBT. this is the first time that I got to really try them out, this group is 3 rounds at 300yd the reason it is only 3 is I was shooting at a state game lands range and you can only have 3 round in the mag at a time, there was a gusty side wind and I got the first 3 on target during a gap in the wind in about 10 seconds. By the time i re loaded it was gusting all over the place again so I called it good at 3 rounds. hopefully I will be able to get it out on some steal at longer distance soon.
