IMR 4227 and the .357 Mugwump

I have most of a pound of IMR 4227 (figure out how old THAT stuff is) that I bought for some forgotten project. Anybody got a pet .357 Magnum load using 4227 that they'd share?

Here's the skinny, straight out of Lyman 47th Handbook.

The only two I've had experience with are the following:

Hornady 125gr jacketed hollowpoint: I used 16.0 grains (start: 15.6, max: 19.5)1.590"OAL

Hornady 158grjacketed hollowpoint: I used 13.5grains (start: 12.2, max:
16.1)1.590"0AL

NOTE WELL: THESE ARE "RIFLE" LOADS AND WERE SHOT OUT OF A MARLIN LEVER GUN.

I've shot some lead slugs to, but these were the two best that showed the best accuracy, out of that rifle.

There's a bunch of loads in the Lyman 47th for .357 using IMR 4227. I use to shoot IMR 4227, but not that much anymore.

Give it to Tom to bring to me and I will burn it in the 357 Max and 357 Herrett.

I like 12.5 grains of 4227 with 200 grain cast bullets in the .357 Magnum.

No offense to the otherwise inclined, of course. :-D

But if you mean his name, I kind of doubt it.

In the old days, Chic was a pretty common men's nickname (for lack of a better term), and Gaylord didn't have the implications it does now (at least not very widely).

I suppose there might have been a few snickers here and there, but I bet there weren't many to his face. ;-)

I use 14.5 grains under a 173 grain cast bullet. Shoots very good out of my NM Blackhawk and n frames. That is on the max side I believe so work up to it. That load shoots better than the same bullet under 2400 or 296 etc.
