I want to thank all for their input answering my question .I was still wondering about why SAAMI
does not redefine the 14,000 psi on the Colt SAA when the original test was on an old iron frame revolver back in the early 20's ?? All they would need to do is list serial number dates.
Thank You
Because like all things, the SAAMI-spec .45LC is what it is. If was something else, it would be (officially) known as something else...sorta like the 9MM+P, .38-Super, and .38Spl+P are, all of which have their own SAAMI specs which differ from their respective parent loadings.
As for the .45LC, there is no SAAMI-recognized "+P" load, so it follows that there is no "industry standard" in that regard either.
As for the "9.0 Grns Unique" load you asked about...my two loading manuals both show 8.5 as being max with a 250-ish bullet when used in a "smokeless" Colt SAA or clone. The only place I see 9.0 or more is in the "Ruger only" section.
I wouldn't be surprised if someone refutes what I'm saying here by citing other sources but be that as it may...the bottom line is that it's your gun, your choice. The deer isn't going to know (or care) about a half-grain of powder, one way or the other.
Hope this helped.
