Well today I did a test at 100 yards with H1000 and 180gr VLD'S and 190gr Hybrid. I shot the 180gr bullet before with RL25 and it shot well at 100 yards. My goal is to get the 190gr bullet to shoot small at 1,000 yards so far it has not been near good enough for competition. 64.5grs of RL25 was the best load I tested and that pushed the big 190gr at 2890fps.
H1000 is supposed to be slower burning than RL25 when you look at a chart but that really doesn't hold out for ever given case you burn it in. 66.0grs of H1000 with the 180gr VLD shot really good at 100 yards and it went 2955fps the exact speed as 66.0grs of RL25
66.5grs of H1000 with the 180gr bullet shot really small at 100 yards and it clocked 2980fps which is really in the sweet spot. The temp was 80deg so it was a good valid test for temp's to shoot in. 66.5grs would be the max load for this rifle .
This Rem. action doesn't have as much camming action as it should . I had been shooting 64.5grs and 65.0grs of RL25 with the 190gr Hybrid with no real problems so I loaded up 64.0 to 65.5grs of H1000 glad I started at 64.0 because that was maxed out and it strung the bullets on the paper. H1000 should not have been maxed out according to the burn chart but it was in this case with a big heavy bullet with a ton of bearing surface.
So it looks like I have to start shooting the 180gr bullet to see how it shoots at 1K. There away seems to be a limit on how heavy and how long a bullet can be in any given caliber for the &mm I believe 180 to 184gr is it. It will take a bigger case than a WSM to push that 190gr bullet safely into the 2950fps zone I know my 7mm Weatherby would do that easily in hind sight I should have chambered that first.
Because I was able to push the 195gr bullet up to 3,085fps out of a 27 inch barrel.
