Works pretty well in 300 Blackout...
It gives me the best accuracy of many powders tried for my, 38-55, 50-70 and 45 cal. smokeless muzzleloader.

Works in the .44 mag .41mag and the .22 hornet and .22 k hornet and .45
IMR 4227? OMG! .410, .357 carbine, .30 carbine, .44 mag, .38-55, 28 ga heavy loads, .303 210gr, .30-06 180gr, .32 Win Spl 165gr Hoch & more...and that's just what I'm currently using it for!
357 Maximum
Works great in 44 Magnum with any bullets. Gives less leading and wear IME. Also burns cooler.
God forbid anyone else gain any knowledge, or have the chance to exchange information.Originally Posted by triggerhappy243
this.
interested in this for the 308, have any more info?
300 AAC Blackout supersonic with heavy cast bullets.
Usually anything the discontinued 4759 was used for only a little more of it. I use it in 30-06, 8x57 and 30-40 Krag.
I like it.

flint45,
I understand fully. - I paid for my first "deer rifle" by peddling dressed catfish (for a buck each) door to door, off my trotline. = a Model 141 pump-rifle in .35 Remington.
(Wishing that I'd been smart enough to keep it.)

17-20 grains of 4227 under just about any cast bullet 150-200 grains. Pressure won't be an issue. Twist rate will decide accuracy; by that statement I mean that a fast twist 308 (1:10) will need a lower charge to maintain an RPM rate below about 140.000. This equals about 1900 fps. Slower twist barrels can handle more velocity: My 30 XCB rifles (30x57) are all 1:14 and 21 grains 4227 gives 2100 fps and group around 1.25 MOA consistently.
Bjornb I agree. I'm getting pretty much the same results with a 30-06 with 1-13 twist 21 grs 4227 works well. For a 10 twist 30-06 19 grs works well
Had poor results today with H-110 in a .357 Max. Going to try 4227 soon.
14.5 gr and a 170 gr cast sized 310 is a minute load at 100 yards in my CZ527 in 7.62X39, mild recoil and lots of fun to shoot
texasnative 46, I wish I would of kept that super blackhawk also! back to the thread 23.0 grains with a 240 grain j-word or lead boolit has always done real good for me.

I use it in subsonics for the 300 whisper and 220(9.5gr) or 240s(10.5gr), 338 BR and the 300 gr SMK(13.2gr) and the 510 whisper with 650gr anything (28.5gr) . Works pretty good but 2400, AA1680 and VV N110 work better. If its cheap and you're just blasting anyway its worth buying.
