Hello,
Are any of you using 4227 in your .45 colts?
Looking for pet data for 260-300 grain cast bullets. To be specific I'm loading them for a FA model 97.
Many thanks,
~Jason Oles

Not a max load but 20 gr of 4227 under a 260 - 280 grain bullet is very accurate and easy on the recoil.

Not sure what pressure level the 97 is good for, but in my Ruger Bisley 21.0 gr of 4227 under a 270-280 SWC is dead nuts accurate @ 1080 fps.

Thanks Paul,
I'm using that same bullet with H-110 and crimping in the crimp groove for a summer load.

I stopped using it as I found at the charge I was using it left a bunch of what appeared to be unburned powder. I can't remember the exact charge but between 18 and 20 grains.

As Mr. Taffin says, Heavy Crimp and Magnum primers. Hank Williams Jr. wrote in first Lyman Handgun Loading manual that came out in the early 90s that his favorite 45 Colt load was 20.0 grains of IMR4227 under a 255-260 grain Keith bullet. 1K for velocity and superbly accurate. Back in the 90s I was shooting a lot of 45 Colt and I found the advice of Mr Taffin to be true and the recommendations of Hank Jr. to also be on the money.
I shot the Hank load in S&W, Colt Model P and Ruger Blackhawk. It worked in all of them.

Even before Hank Junior/Lyman that was a load I recommended. I had had a Colt New Frontier 4-3/4" fitted with a tight .45 cylinder. No matter what I tried it was just an average shooter and then it happened! Lyman Keith #454424/20.0 grains of #4227 and the result was one hole groups. Ever since that time I have told readers if you can't get a .45 to shoot try #4227.

I've used 4227 in my 45LC with bullets ranging from 240 to 310 grains. Even with a heavy crimp and magnum primers I get a lot of unburned powder not to mention lower velocity. I usually load with W296 or 2400.

CHARGE FOR CHARGE THE SAME WEIGHT #4227 WILL GIVE LESS MV THAN #2400. IT TAKES ABOUT 10% MORE #4227 TO EQUAL #2400. BUT AT THE TOP END IN SUPERMAG CASES #4227 EQUALS H110/W296

If you're eight pounder is "somewhere" you definitely have too much stuff!
