heavy loads for 625-5

[hawken]

I can find no information for the .45 ACP loading a 250 Gr LRN .452 with titeGroup. Most manuals only list the 230 Gr. Can anybody share this information. I have a abundance of titegroup and it does well with lighter bullets.

titegroup gets squirelly when you get into the heavy bullet higher pressure range.
if i were to try this powder, i'd start at about <4 grs and proceed SLOWLY.
in the acp with 230's i use 5.2grs and only 6grs in the 45 colt with the same 255 gr cast boolits.
i shoot 255's [cast] in my 625 but use unique, and have gotten to 6 grs on the top side, but use 5 grs more frequently.

There was an article quite a few years back in IIRC, handloader magazine where a guy as loading 250 gr. bullets in a 1911 semiauto. IIRC, the powder that worked was (GASP!) #2400. You could probably use his data as the gun didn't blow up. In fact, I was tempted to give his experiment a try myself. The problem is, to find that article to copy would entail digging through something like 30 years worth of that magazine. I was going to try the load in my old model Ruger .45 that has cylinders for .45 Colt and .45 ACP as I have a lot more ACP brass than Colt. Just never got around to doing it. Just wasn't sure I'd want to subject my 1911 to that kind of punishment as I believe the slide would have been slammed back quite forcefully. I think he also tried other powders but apparently #2400 was the one that worked best.
