IMR 4227 - good results

[Cosmic_Charlie]

In .357 mag. 170 gr. Keith style boolet over 12.6 grains. Pleasing recoil impulse and accurate. This powder is listed frequently in the Lyman Cast Bullet Handbook.

It’s my goto powder for 22 hornet.

In my 357Max it shoots some of the best groups I’ve ever shot. Very good powder in lots of cartridges.

I use quite a bit of 4227 in my 30-30's. I'm about to give it a go in a 38-55. I really like it.

Just started with it, but it looks promising in 300 BLK.

i like this for my 686 use 158gr linotype and 14grs of imr 4227 really accurate up to 25 feet.

My Go-to powder for full charge loads in .44-40

Is anyone finding this to be a good replacement for SR 4759?

A tad slower but should work out alright. Converion table here: http://www.adiworldclass.com.au/powder-equivalents/

Pretty much what I use for my loads. The gents at the club reckoned it sounded hot but no pressure signs and the little Security Six sure patterned well with it.

[Randy Bohannon]

Good powder for the .300 B.O. and heavy .45 Colt rifle loads that is what I use it in

450 Bushmaster and 460 Smith and Wesson, 300 grain Hornady SST. Deer stompers.

@boingk thanks. I had not seen that chart before.

4227 in the 32 mag,and 327 mag,,is almost magical!!

[farmbif]

ive always liked the way 4227 shoots in a bunch of different calibers. more often then not it provides excellent accuracy for some reason. I can put up with the unburnt kernels in the barrel.

[DonHowe]

4227 is my go-to powder for breechseated .32-40. 14.0 to 14.5 grains with proper fitting 200gr plainbase in a good barrel shoots better than most shooters can hold.
When I first started shooting 180gr cast in .357 mag 35 yes ago there was not much data. The load I settled on (12.5gr?) was a bit slow by later standards but very accurate from a Blackhawk.

[MostlyLeverGuns]

I like it for 45 Colt, 218 Bee with boolits, 44 Magnum, mild 30-30, 32 Special, other mild loads with boolits in other rifle calibers. Works a lot like 5744 in most calibers, cheaper, easier to find (usually?).

[Shiloh]

4227 is good for cast in .30-06.
Ever since my IMR 4759 was used up.

Works for my 357, 41 & 44 mag, 45LC and 30 carbine. I don’t get unburnt grains, not like I get with Unique.

[Larry Gibson]

I shot many a 170 Keith bullet over 14.5 gr H4227 out of an OM BH. Ran right at 1300 fps out of the OMBH and was a good load. Picked up an 8 lb jug of Hodgdon's IMR 4227 yesterday at the LGS for $275.

[T-Bird]

I use it in JES 38/55, 16.5 or 17 gr with dacron and Lee 250 pb boolit. Shoots real good at roughly black powder velocity.
