the thing about the 45 is so many powders work well. If you see it listed for your bullet weight in a reloading manual, it will most likely perform good. The round is a tack driver so this adds to this equation.
I do notice that my new short barrel Kimber SIS ultra likes the rounds a little hotter. Meaning i find the slide not fully locking up the next round in the chamber, not every round mind you. This must have to do with the stronger type of recoil springs that the shorter barrel 45s often have.
At first i thought the pistol just had to break in a little more. But now i think other wise. So i am reloading a little on the hot side for this one. Which really works out well, considering the shorter barrel will give less velocity than a 5 inch type model will (full size).
yesterday at the range i had came up with this conclusion by using both 230 grain FMJ in two different loads. One load had 5 grains of bullseye and the other 6.3 grains of win action pistol. bullseye load was not fully cycling all the time, which kind of upset me a little bit because i like this load alot.
by the way win action pistol is now sillouette from Ramshot, same powder. Also just read H38 (Hodgon) is the same powder as 231 (winchester) winchester is selling off some of thier powder rites or are merging so to speak. This practice has been going on for years. Hercules did it with bullseye back in the late 60s i think.
If you look at load data for a given load you will see the same grain weights across the board for both powders. This is often the first sign of the merging or selling

process to another powder firm.
Sometimes you can get these powders at a reduced cost, i di this with win action pistol a couple of winters back. I was able to grab 4 1lb canisters i could have or should have bought the whole case. I think i paid 5 dollars a can. I had to go back to a the older Lee manual to find some load data. i noticed the newer book did not have it. Make a long story short i seen loads at different weights with the same amount of powder for the two. I emailed customer service or contact to Ramshot powder company. A representative was nice enough to email me back telling me yes that they now have the rites to this great powder. and it is now under the sillouette name.
I did go back to the range for the rest of that case of powder, but someone beat me to it. So discontinued does often means it was sold to one of the other powder companys. Average person tends to think that something is wrong with the stuff. In my case the owner of the gun shop was hearing that his customers could not find loading data in the revised (new) loading manuals. so as not to have the stuff laying around forever in his stock he decided to have a sale.
My advice is keep and buy older reloading manuals when you can, besides i like being well read for this reloading hobby of ours.
Take care everyone, happy reloading, Jack
