I have a question, I notice Hodgdons Reload Data for IMR SR 7625 is as follows

For 230gr FMJ

COAL 1.200

Min- 5.4 12,2000psi
Max- 6.0 16,600psi

If I'm loading my COAL at 1.260 can I increase the load over the Hodgdons MAX?

Thank you

Well, you MIGHT, I sure wouldn't increase it MUCH, and, all you will be doing is making up pressure loss for the extra length, which means velocity will remain similar, not increase much, if any.

Notice this, tghe max. pressure of .45 Auto is 3,000psi higher than the max load there.
It is fully likely that any more than 6.0gr, or 16,000-ish psi was not a good stable pressure.
Say, maybe 6.2gr may have generated 17,500psi BUT it may have been very unstable, wavering from 17,000 to 20,000 shot to shot, adn so 6.0grains may be SUITABLE, more than 6.0gr of 7625 may just be UNSUITABLE for more velocity, and/or pressure, in that loading.

I don't always venture out into the sub-freezing darkness, but when I do, it is hunting season, and I carry a Browning. Stay hungry my friends.

^^^what he said.
I have used SR 7625 for both shot shells and for .45 ACP loads. I like it. It meters well and, in shot shells, allows for lower pressures when I am making up shells for my old Parker.
I have kept my .45 loads - target loads with 200 gr. LSWCs - down at the minimums. Shoot just fine.
