Start low
That's 4-5grs less than max in both barrels I've had.
He's gonna end up shooting 160AB's anyhow.

I started at 67gr H1000, got up to 70.5gr before seeing pressure, backed it off to 68.5gr and that's where she lives. Thats just my experience though, always start low

Published data
Hodgdon Reloading 24" barrel:
H1000 67.2 2968 Max load
Retumbo 70.0C 2985 Max load
Hornady App 24" barrel:
H1000 67.1 2950 Max load
My personal data 22" barrel:
H1000 67.6 2825 F215M
175 EH have been running 20-30 fps slower than 175 ELDX
F215M have been running 20-30 fps faster than CCI250s & F210M
175EH seem to like 0.040 jump in my rifle. 3.380 COAL
I haven't tried Retumbo yet. My rifle seems to like RL26 with loads backed off of maximum giving me the best groups and SD/ES.

I just went down the 7 prc road again
I have a 22" bbl and still in load development
Stage But I might of found the load i'm going to shoot as long as it holds together the second trip out. I'll find out tonight
Shooting 175 EH with RL 26 and 215m in adg brass seated 0.040 off I'm getting 2910 fps.
If it holds together tonight and repeats itself I'm gonna call it good.
Retumbo did not work very good. Large groups and right around 2900 fps.

Welcome from Illinois!
Get group we have here!!
I'm driving down it right now, just started trying some Apex Afterburners. I've had worse starts. Thats a fouler plus 4, .5 gr increments.I just went down the 7 prc road again

I'm fooling around with a 7PRC with a 26" Bartlein Carbon bbl. It's been a bit finicky so far but I'm hoping that it was either the scope or bedding that wasn't just right.
Yesterday I tested a few new loads with different powders and bullets. I shot a single group with the 180 Berger Hy and 68.0 H1000. Velocity was 2,926 fps with an SD of 5.4. The group came in at 1.40" at 418yds.
If that can be repeated - I'm done. LOL

Did you end up with LR or LRM primers?
With H1000 and N565 with 180HT I can tell no difference, in pressure, velocity or accuracy.
If your group size doubles you are still done, or about .1 gr from it.
