IMR 4227 in 357 Mag

[1972RedNeck]

Awhile back I ran across a hand loading chart for IMR 4227 that had it listed at 21 gr (compressed) for 110 gr bullets in a .357 Mag. I can't find the chart again and was wondering if I was just seeing things or if this is a feasible load. And if it is, what is the OAL?

In most cases, you cannot get enough IMR4227 in a handgun case to be dangerous, even when compressed. My best shooting .357, .44 and .460 loads with IMR 4227 are at or slightly compressed. That said, IMR 4227 works best with standard to heavy for caliber bullet weights. I would seriously consider something else to use with your 110s.

^^ ABSOLUTELY ^^

Loading light bullets with "magnum slow" propellants (W296/H110, 4227, AA4100, Enforcer, N110; and maybe even the slighter faster 2400 and AA#9) is an exercise in excess.

I used to do this (110/W296); the result was just a big mass of flame and thurst recoil; sans any kind of consistency. Of course, at the time, I thought it was cool. And then I grew up.

About the only way a 110 grain bullet should be loaded with 4227 is if it was going to be shot in a lever action carbine or 20". And even then, it potentially brings about new issues (bullet disintegration, fragmentation, etc.).
