[QUOTE="Tidesloe, post: 2891705, member: 47761"] I got out and shot a ladder at 580 yds with H100V yesterday. I had that and N550 loaded up. I didn’t shoot the N550, and possibly won’t. I did shoot 2 N550 loads at 1 gr below where I started seeing ejector marks the other day, just to get on paper. They gave me pronounced ejector marks, heavy bolt lift and 3080 fps. It was 30 degrees warmer yesterday and this told me N550 is very temp sensitive. H100V didn’t show that and seemed to be fairly stable. I’m liking what I’m seeing with H100V. I shot 2 4 shot groups starting at 60.2 to 61.6 in .2 gr increments. I had 1 flyer in each at the same elevation but 4” right of the group. Don’t know what happened on either one of them, but kicking those shots out put the other 3 in each group at 2.7”. Not bad, but hoping to shrink it down a little. Puts those groups at .4 moa at 580 yds. 60.2 - 2980 60.4 - 2966 60.6 - no velocity 60.8 - 2988 61.0 - no velocity 61.2 - 3017 61.4 - 3037 61.6 - 3034 Started seeing slight ejector marks at 61.6. It was in the 90’s vs mid 60’s the other day. I think the H100V is showing promise, and what I’ll continue with. N550 was clearly too temp sensitive. Higher velocities, but temp sensitive and it comes at more cost to throat. I’m liking what I’m seeing with H100V, and thinking I’ll probably work on the 2980 to 3000 fps range, and see what I come up with. [/QUOTE]
