You'd be correct there. ;-)

It's a great upper end powder for lead bullets in any of the magnum rev rounds.
Extremely popular powder with us breech seatin' schuetzen shooters. 14.0 gr. of IMR-4227 breech seated in a 32-40 case under a 200 gr bullet, wonderfully accurate. Conventionally loaded I also use 14 gr in 30-30, 32 win. spl. 7x57. 16 gr in 30-06, 18 gr in 38-55 and 35 whelen, 20 gr in 45 Colt. The only thing about 4227 I don't like is running out of it.

I recently worked up some loads for my Marlin 1894 CB in 45Colt with some Ranch Dog 290gr. Shot several loads but 19.2gr of 4227 was acceptable (avg velocity @ 1215). 1 & 1/8" at 50 yds. Most of five round groups I chronographed had extreme spreads around 60 or so. Did have a lot of popcorn in the barrel. Had some Marbles sight issues so decided to have another look another day.
Try a little bit of crimp on your loads SgtDog0311 and see it that helps the burn.
When the .357 mold came along without me having anything in that calibre I thought it was actually a sign I needed a 35 whelen. Maybe it was for a .357 lever - why so many choices?Quote:

Thanks Jeff... I'll sure do it.
45lc rifle loads and its my #1 22 hornet powder. My 308 starter loads were decent and I plan on trying it in 30-06.
I heard it referred to as a 2400 alternative so if 2400 can be used you can find similar 4227 data. Us it meters beautifully. If it hadn't been for Bullshop I would have never picked up any....
44 sp. and 45LC it it outstanding! but it needs a mag primer to burn it all because of the slow speed of the powder.
I have been reading Timothy Mullins book Letters from Elmer Keith. This is page 96:

Forgot to add 357 Herrett 125-180g loads. I get less unburnt powder than my R7 loads. My 300WBY shooting 224g Lyman is looking promising with it too.
I use it in my 357 and in my 7.62 x 54 works very well in both
