What kind of speed are you getting with H1000? I'm planning a build but will likley have a 22" barrel.I’ve been testing some h1000 in my 20” saum. Speeds are sloooow. Going to work up to max case volume/pressure. Whichever comes first. Then going to try some rl26. Rumor is they’ll speed up until they hit 100 rounds. I’m at 35 so I have a way to go. I’m curious on the h4350 but I’m running 180 Eldm and heard the h4350 is for light bullets.
My last load with 43.0 was 2680. No pressure signs. Going to keep going. Would like to get 2750.What kind of speed are you getting with H1000? I'm planning a build but will likley have a 22" barrel.
id imagine H4350 would work with the 180 eldm'sI’ve been testing some h1000 in my 20” saum. Speeds are sloooow. Going to work up to max case volume/pressure. Whichever comes first.

Yeah 63.0. Good catch! Not sure why it’s so stinking slow but I’m hoping for a speed up. I’ll test it out Wednesday and see where I hit pressure.There is some data out there where benchrest and fclass guys have done well with 4350 and 180s. Pressure seems to come in the 56.x in norma/adg and a longer throat. The case fill ratio isn't great at those charges but i wouldn't be afraid to try it especially in a short barrel.
Did you mean 63.0? My previous barrel pressured out around 64 h1000 (after breaking in and speeding up) and that was in the mid 2800s with 22" barrel.
I tried H4350 with 145 CEB Lazers and 58-59 grains seemed about right in that barrel.

Down to my last 6 virgin brass. Going to be using 1x fired. Just trying to get closer to 2750. I’m curious to see what rl26 does as well.I bet you'll see a speed up with more rounds on the barrel and also with fired brass if you're shooting virgin now.

Your initial load is 65gr of h1000 in a 7saum? .I loaded 20 rounds last night for my 22”. Using h1000 65gr with Berger 168 gr classic hunters. Cbto 2.415”. Have never shot this brass or gun. Based it off this data. Thoughts?

Personally I always start with a ladder test, building up to pressure. Especially in a new gun/chambering. 65.0 grains may be close to Hodgdon's starting load, but another way to look at it is it is only 2 grains below their max, or less then 3%. Not alot of room for error.Will it blow up in my face???? I started on the lower end and loaded .020 off lands to be as safe as possible.
The only powder I have worth a crap for this cartridge is h1000. I’m working on getting some h4831.
