I’m definitely happy with it. The low/single digit SD’s were also surprising to me with such a slow powder in a short barrel.I would be ecstatic with 2820 out of an 18"
If I get that out of my 19.5" with the 175 EH I'll be happy. 2850 is my goal but I'll let my barrel decide.
I've got too much H1k and 4831sc to go and try the vv stuff but if I can't reach the speeds I want with H1k I might try some of the 570...your results are very promising.I’m definitely happy with it. The low/single digit SD’s were also surprising to me with such a slow powder in a short barrel.
I will say the added 200fps did not go unnoticed on the recoil side of things though. It’s not terrible but it definitely lets you know it’s there. Likely won’t be spotting impacts at 200 yards anymore.
H1000 might be able to do it in a longer barrel but I don’t think it would be able to in my 18” without overpressuring.I've got too much H1k and 4831sc to go and try the vv stuff but if I can't reach the speeds I want with H1k I might try some of the 570...your results are very promising.
What case fill percentage do you think you are at and how compressed?
I've found that a lightly compressed load produces good es and sd. Not always but more often than not.H1000 might be able to do it in a longer barrel but I don’t think it would be able to in my 18” without overpressuring.
It’s very full. If I hadn’t used the tooth brush to settle the powder it would have been crushing a bunch of it. These sat with almost no crunch
I’m at 2950 with the 175 eh and h1000 in a 22” barrel. This was with around 50 rounds through the barrel, I suspect it will get a little speed up here shortly. I’d guess you’d get to 2850 with 19.5”, but yeah, let your barrel tell you where it’s happiest at.I would be ecstatic with 2820 out of an 18"

Nice, thats good news to me. 2950 out of a 22 is greatI’m at 2950 with the 175 eh and h1000 in a 22” barrel.

Damn that is quite a bit faster than I am getting. Pretty close to where I’m at with 73gr, but much faster than where I was at 70gr. Is that once fired brass or virgin?I landed at 70g of n570 and a 180 eldm. 18” barrel right at 2835. This was a 8 shot group and some suppressor mirage lol
Ok. This is Virgin Peterson. Maybe I’ll see a jump after I get these all fired. I think I’ve got 149 left to goPeterson once fired
No regrets on going short, and honestly had good performance this season at 2620fps with the 180 hybrid so I’m pretty much ok with whatever load ends up being consistent and accuratePossibly. The virgin brass was close to same velocity in my chamber. These short barrels seem to be shooters though haha
I think n565 would be your best option. If you look at the burn rate chart below. Ive also used rl26 but ran out and switched to n565 for my 6.5prcI have a load I like with 168LRX 67.5g RL26 2974fps, but can't find RL26 anywhere, so looking at switching to N5??, curious what folks would recommend as the best "similar" powder N560, N565, or N570? I have no experience with any of those.
