Works exactly as I needed to, creating my favorite .350 legend load.

5 IMR 4227 - Sharps Rifle
Posted by Bob K on Oct 22nd 2021
With the current shortage of reloading supplies, recently I purchased some IMR 4227. This powder has historically been used for magnum pistol loads. However, the manufacturer of the hard cast bullets for my Sharps do recommend this powder for reloading 45-70. I've used this powder with 300 and 405 grain bullets, with excellent results at 100 yards. Unfortunately, that is the only distance available to me where I reside. The load is very pleasant to shoot. normally 50 rounds every times I go to the range. With the cost of commercial ammunition, reloading is a must.

5 Perfect powder…
Posted by Bill Eisel on Sep 30th 2021
…for my M1 carbine. 12 grains of 4227 with a 115 gr LRN and a 1.5” group at 50 yards. Hodgkin Powders are the ultimate, IMO.

3 IMR4227 Smokeless Powder
Posted by Robert S on Sep 11th 2021
This powder was all I could get to reload my .44 magnum loads. Previously I used IMR 800 X powder. This powder takes twice as much in grains as 800 X. Therefore a pound of this product will not go as far as a pound of 800 X. Despite this the powder shoots fairly well and does not leave a lot of residue. It is fairly granular as compared to the 800 X powder which is lighter and is in disk form.This powder is more granular like small grains of sand. If I had the capability to get anything that I wanted I would choose the 800 X over this product.

5 44 rem mag and 30 carbine powder
Posted by MCAK on Apr 21st 2021
I use this for 44 rem mag and 30 carbine loads. The old wc military powders had issues in cold weather. I live in alaska. I’ve found 4227 much better at frigid and below zero temperatures than h110. Loads well and shoots well in the application I’m using it for. I have thought about working up some 45 long colt and 454 casull rounds with 4227 but haven’t researched it and haven’t done it, not sure if it’s even feasible.

Good consistent groups out of super blackhawk 44mag with cast and some of the best accuracy I've had in my 300blkout with 150s
