I looked it up as best i can tell it was 25 gr H-110 as shown in the Hornady 3rd. addition , with either a Hornady 240 hollow pt or a tmj from speer or serria sil. bullet .
the load is a little over for the speer bullet but never gave a problem in the ruger , but did in the S&W ( my fault ) i advise against the load for a speer bullet or sierra .
Ok it was the loads for the 45 colt that had higher press. loads for T.C. & Ruger , i had a book with loads for IHMSA guns , but can't find it , that may be what i was thinking about , but i was mistaken about the standard books please forgive me !
I neither had heard of a S&W frame stretching , not sure that was the best term to use , but that is what the gunsmith used to describe it , what happened was the bullet. pin would not line up as it should , the frame was out of alignment , and to get the gun to lock the cyl. in place took alot of force , the new pin didn't help ! the hole where the bolt came thru. was messed up also ! the gunsmith sent it back to S&W when it came back it would shoot but it spit a little out the cyl. bbl. gap and accuracy was not typical S&W . i was charged shipping only and that was by the gunsmith .
now lets look at the 45colt loadings which is where we should have looked before they do show the Ruger taking a stronger load ! SB it was in the late 80's maybe 90 , the cyl thing may have contributed to it , had not heard that before but something went wrong ! a cyl. backing up and a to hot load or 6 may have been it .
the powders you listed i used very little because they were easy to over load , i still have over half the first LB. of bullseye i got in about 1976 .
Now i in no way blame S&W in fact carry one everyday ! just think ruger is stronger , will admit S&W may be the better balance of power and strength in a carry 44 mag. ! ruger on the other hand could probably be used as a crow bar with no ill effect
