1885 7 mag loads?

I have some Sierra 175 SPBT's, 120 grain Hornady HP's and Nosler 150 BT's. But I can always get something else if I need to, just too time consuming for me right now to load a few then group 'em trying diffrent powders and charges, if you have some data to pass on I'd like to try it.

Went by a buddy’s place today and tried three loads and then he offered a fourth one to try. 145 grain Speer Grand Slam loaded with 65 grains of IMR 4350. Don’t look for it in the book, they don’t go this high! LOL Just wondering if anyone else has had any experience with a similar load. I didn’t see any pressure signs and got a three shot 100 yard group that was just over ½ an inch.
