I have a 300 win mag sendero sf2. Has been bedded and a timney trigger. A friend and I have been working on a round and having a hell of a time getting a round that will go near 3/4 moa or below. I would like for this gun to be able to shoot well a long ways I have loaded the following and am using h1000 powder. Fed 215 and hornady brass. The 78.5 gr is 200 gr eld-x bullets and the 74 gr is 220 gr eld-x bullets. Those are the bullets I currently have to reload with. Any help or recommendations would be greatly greatly appreciated. I just want this thing to get dialed so I can start shooting more and getting ready for the season. 78.5 4.25 was 3.36 moa 78.5 4.28 was 2.40 moa 78.5 4.31 was 1.23 moa. 4 round group was .86 moa. (One flyer by shooter) 74 4.25 was 2 moa. 74 4.28 was 1.1 moa 74 4.31 was 1.61 moa. .91 4 round group. (One flyer by shooter) Perhaps the 74 grain range loaded around 4.28-4.31 shows promise? The 78.5 may be good up at the 4.31 range. Maybe even pushed some more? Thoughts.
