Sir, Speer used to list load data for a jacketed 260-grain bullet in .45 ACP/AR, and I'd assume they still do. (I don't have a current Speer manual.) You might also check Lyman's data. You can also check the data at www.handloads.com, but be aware that most of it is user-submitted and may or may not be safe in your gun with your components.
Usually load data differs for lead and jacketed bullets. It's unwise to mix and match, particularly with heavier than standard bullets.
Hope this helps, and Semper Fi.

Both Unique and AA#5 will work well for you. Actually, AA#5 was specifically designed for use in the .45 Auto.
As a side note, capitals and punctuation would make your post easier to read and understand.

I don't use anything heavier than 230 gr. bullets in my 45AR brass. Simply use the same load as my 45 ACP to replicate factory hard ball.
For me that is 6.0 gr. of Unique and a 230 bullet. No hot rod here...

Try 6grs Unique under 250 to 260 gr swc seated to the top of the crimp groove. This works well in all .45acp revolvers, and keeps them out of auto loaders. You may want to work upward slowly, but probably don't want to go above about 7grs. If this is for a 1917, I would quit at 6.5, but work up slowly in your own gun. Be safe..........

First, you need to be aware of the seating depth you'll end up with. All bullets of that weight won't seat the same. Here's a comparison of 4 bullets .452".
The Oregon Trails bullet seats very deep and that raises pressures, especially in small cases. The bullet on the left side is 270 gr and seats the shallowest of the four. The RCBS is also a 270 gr bullet and it seats at the same depth as the H&G 200 gr clone.
Next, you'll probably have to use older data for what you're looking for and it'll probably be found in the .45 AR section, like this that only goes up to a 240 gr bullet, but Lyman only goes to a 238 gr bullet:
BBHFarm Gallery :: Speer #8, Speer Inc, 1970 :: aab
BTW, that Oregon Trails is only 255 gr.

John,
The Lee manual has loads for bullets of that weight too. That means that they are out there somewhere because, they just gathered data and compiled it into their book.
Go to the websites for the powder manufacturer and see if they list data for the bullet/cartridge combination.
Hope this helps.
