I'll be running this rig with a 26" Douglas heavy varmint barrel 1:8 twist. New to long range shooting and was curious if anyone can offer any load suggestions. I went with the H1000 powder and 180 grain bullets, Peterson brass.
- Thread starter Grim's Reapers
- Start date
Hornady says (with Hornady brass and Winchester WLRM) 57.9 to start and 67.9 as the max H1000 load.
Thanks, I looked at load data charts for it, but was more curious as to which muzzle velocities with H1000 and 180 grainers were getting better results way out there at 1000 yards. I know faster is not always better. I'm probably asking a stupid question in retrospect because I suppose every barrel prefers something different.
30” barrel is putting me at 3030fps. 1-8 twist.
Problem is at that twist rate about 5% of my bullets are blowing up midair. Jackets are not holding up. However transonic stability is also bad, so once it hits transonic, it start tumbling.
Out to 1500 yards, it’s a hammer (when bullets stay intact). At 1950 which is further I’ve had it, it had no consistency.
See hit on steel at 1950.

Uggggh. That's not a confidence booster. I've heard tell of them coming apart at velocities like that. The max I'll probably get out of H1000 before pressure signs is in the 2920 range. I hope I don't run into that problem because I have about 400 of those 180 ELDMs. LOL
