[QUOTE="mullmann03, post: 3063822, member: 60122"] I just finished up testing with H1000 in the 25PRC. At .020 off 57.5 and 58 grains opened up. 56.5 and 57 almost over overlapped so I went with 57. I am switching to H1000 over N565. I was having to clean the barrel after 20-30 rounds due to groups opening up. In my experience with H1000 in a 300RUM I could go forever without having to clean and groups stayed the same. C6 7T Barrel 21 5/8" suppressed New ADG brass BR-2 primers Berger 135 .020 off lands, 2.380CBTO 56.5G 2950 57 2970 57.5 3000 58 3030 heavier bolt lift. EDIT: 58 grains of N565 was averaging 2940 59 pressure [/QUOTE]
