Load Data for 327 Mag

[MountinMan]

Where can I find load data for either 327 Mag. 125gr. FNGC or 130 gr. FNGC Bullets using I Ruger 327 Mag.

Lyman cast bullet handbook, 4th edition (2010) is a start, but you will have to cautiously experiment for heavier bullets not listed. Compressed caseful of H or IMR 4198 is safe, but not most efficient in revolver. 4227 should be safe with a compressed case full with 120-grain and lighter bullets based on experience with. 32-20 and .30 Carbine Ruger.

You aren't going to find data for them. You will find loads for bullets the same weight. It's then on you to work the load up.

MP 300 puts the speed on the .327

AA#9 is a top powder in the 327, and .32 H&R mag. Until I tried it in the .327 I wasn't sure what AA#9 was good for.

[MountinMan]

Okay, Thanks for the input. I did find some info using AA#9.

There was a Handloader issue early this year w/ 327 data in it. I think it was this year. Everything runs together any more. I will check to see which issue it is tomorrow.

IIRC, Brian Pearce wrote an article on 327 loads in the February 2015 issue of Handloader.
I have tried a number of his loads and IME Power Pistol was a bust, Unique wasn't much better while H-110 was the clear winner, though Accurate 9 was pretty good. My best load thus far is a 100 grain NEI SWC over 11.8 grains of H-110. I have managed several 1 inch 25 yard groups with that one out of my 7 1/2 inch Single 7. My 5.5 incher prefers AA #9, 12.5 grains with the same bullet.
the bullet in question is 3rd from the left.

I have a 28-327 Schutzen rifle that I will be shooting cast Bullets from and looking for some load data to start with.

Looking at the data published in this article at the 100gr. Hornady XTP over Accurate #9, it reports a max load of 12.4gr. I'm curious how max was determined. The Western Powders Handloading guide v. 7.0 lists the range for this powder and bullet at 11.7-13.0gr. I tested this combo in an SP-101, and stopped at 12.6gr when the brass was just a bit sticky on ejection, but I had very consistent velocity steps up to that point, and settled on 12.4gr.

I'm not asking to look smart. I just want to make sure I'm not doing something that will blow my gun up.

Yes it would be interesting to know how he came up with maximum loads, I use Win 231 and 100 grain lead bullets in my GP100 but I'm no where near max.
