Sounds like that rifle is shooting well for you and with good velocity. I hope to get back out this evening and try 76.0 and 76.5 grains.
Yep, took her out this after noon and was drilling a hole in a grapefruit sized target at 800 yards, then again at 1100 with a 11 mph 9:00 wind. So took it to 1744 yards and was all around a 1 moa target. Not bad in that wind for a lowly ole 300 win.
Hope your comes together for ya. I look forward to your results, stay after it.
Made it back out tonight to shot. Tried 76.0, 76.5, and 77.0 of H-1000, WW cases, 215 Federal primers, and 215 Bergers. Not sure if I pulled the one with 76.0 grains or not. Don't be shy tell me what I'm doing wrong.
Jeff are you using Federal primers, if so are you using the 215's or 215M's?
76.0 - 1.347 CTC
76.5- 1.334 CTC
77.0- 1.72 CTC
I have been 0.010, 0.050, 0.090 off of the lands, with 0.010 and 0.050 both looking similar with a slight edge going to 0.010.
No mirage on this group.
