[QUOTE="KH_Outdoors, post: 3100820, member: 123559"] Got out and tested the 225 McGuire CR's. As hoped, this combination is working out better than the H4350. Ran my pressure ladder up untill I hit pressure at 76 gr of N550 with a bolt click & slightly heavier bolt. Shooting all charge weights at 100 yards, it started stacking together at 73/74/75/76 gr where I stopped. 74/75/76 gr charges were all nearly touching. Pretty typical of what I've seen with the McGuires. Loaded up three rounds of each charge weight 73/74/75 gr of N550, staying one full grain off of 76 gr where first signs of pressure were. Here's where we landed! [ATTACH type="full"]569953[/ATTACH] [ATTACH type="full"]569954[/ATTACH] I'll load up a few more at 75 gr of N550 coming in at 2950 fps to go verify it repeats! [/QUOTE]
