Has anyone tried H1000 with this cartridge and 180 Berger target hybrid bullets. 30” barrel. ? H4350 has me scratching my head. With similar cartridges h1000 has a lot better case fill than h4350.
 
H1000 is probably getting too slow. I should say that they probably can’t get enough powder in the case to achieve the velocity they want. Most people in F class are using N555. Which is similar to H4350. It wouldn’t hurt to try H4831Sc or N560.

Or N-165. That will produce the velocity range most look for, and with good case fill. Burns cool, too, which is a good thing, results on target being equal.

Looks like a perfect fit in this simulation. 101% case fill, 100% burn. I'd definitely take it for a test drive

That GRT simulation is using the SAAMI 7mm PRC case, not the 7-6.5 PRC. The 7mm PRC's default case capacity is 82 gr. of water, and my Lapua formed 7-6.5 PRC brass has a measured case capacity of 69.35 gr. of water. As you can see, two very different animals. I don't think it's possible to get 70 gr. of H1000 in a 7-6.5 case.

H1000 in the short mags is tough because you run out of case capacity before you get to a nice pressure usually, especially at magazine compatible lengths.


R26 is a dream in the short mags however with it’s extra energy and higher density.

Good catch, didnt notice that
