Hello the Wire, anyone out there using IMR 4227 for their smokeless loads? I read somewhere that it was one of the older smokeless powder formulas and was high volumn, slow burning. I loaded several (250) rounds over the weekend in 38 cal. extra long colts (357), using 10 grains, with a slug wht of 125 and 148 grains RNFP, using federal mag small pistol primers.
Looking at the loading tables for 44 mag and 45 LC, they show as high as 17 grains of the stuff, and show that it is actualy a compression load with 240-250 grain bullets. Anyone have any luck with this powder. I might like to load some of the larger calibers but did not want to load until I tried it on the smaller calibers first.
I was wondering if anyone has crono'ed the stuff for similar loads?
I found the loading Data in a Lyman loading manual, the manual that IMR puts out know calls only for their Trail Boss for CA loading.
I do not have a lot of luck firing the lower, volum powder, even though a lot of manufactuer's claim their powder is not positional, I do get a lot of unburned powder using the less than full case loads in the 5 to 6 grain catagory for the 44 mag loads,
I was wondering if there would be much blowback using my 92 winny, or my new 66 cabine using this powder.
Any information or experience with this powder would be greatly appreciated.
I have tried several loads using 4 or 5 different kinds of the new heathen smokeless, and the best luck I have had to date is using Bullseye from Alliant, but that stuff is sure fast burning, and low volumn (Very High gas pressures). It does seem to be truely non-positional but there is a lot of air space in the bullet cassing.
