.327 Fed Mag loads

[Rodentman]

Do these loads sound acceptable in the .327 Fed Mag? All using Hornady XTP's 100g and Magtech 1.5 SPP.

10.5g 2400
4.8g Titegroup
5.0g W231

My research indicates these would not be excessive but due to the high pressures in this caliber I thought I'd ask here before I start loading. Also, what do you suggest for a good H110 load, about 13f?

Thanks!

I have worked up loads to sticky brass with many powders in 32 S&W Long.
The most power I can get is with 85 gr Hndy with LIL'GUN or 800X.
No load books were involved.

Some tell me that 110 gr will do better.

Check out the "Reloading Pages of M.D. Smith". Most of his loads there are maximum so be careful.

I think the bullets of 85gr or less are made for the S&W short and long, these bullets have a very short bearing surface and won't stabilize in flight at 327 mag velocities.

I think I read somewhere that American brand 327fed mag shells at 85 gr. are loaded down to the 1400's because of that reason.

I am going to load for this cal. also. It will be interesting to say the least. It is still relitively new.

I won't suggest any loads for this because it is so new and I haven't tested them yet, but according to MB Smith your numbers are in line with the mid range loads for this. I will also be starting in the low to midrange area.

You may also find this to be of interest.
Read about the primers used toward the bottom of Speers load data for the 115gr about using small rifle primers instead of small pistol primers due to the high operation pressure of this cartridge.
I wonder if that is something we both want to start doing.
In case the attachment doesn't go through, look at Speers new load data that isn't in their latest edition of reloading manual.

Thanks for the responses. In fact, I got those loads from "Reloading Pages of M.D. Smith" that tightgroup tiger mentioned. I bought 100g bullets for the .327 fed mag and some of the 85g bullets for the H&R mag caliber. I also noted the Speer page comment about using SRP. I have some of those for my 5.7x28 loading. I'll keep an eye on the SPP that I used and see how they look after firing. I usually don't go to SRP in a pistol unless specifically recommended, which it seems that Speer is not doing.

Anyway I am anxious to test the loads and arrive at a favorite without going to the highest loads. I try not to push the envelope. No advantage for me. H110 loads are close to the edge anyway. At least that's my feeling with H110 in the .50 AE.

I figured you probably read everything that I have read, it's pretty easy to find.
I noticed their is not a lot of wiggle room between min and max loads on these. I haven't got my dies yet and brass is still hard to get so I haven't started playing with these yet, especially since my wife took my new sp101 and wrapped it for a christmas present. bummer.
I'm wondering why the minimum loads are so tight to the maximum loads, maybe they are trying to keep the velocities high on both to justify it over the 32HR mag. Just a guess.

I noticed their is not a lot of wiggle room between min and max loads on these.

When I started grabbing powders and bullets and making up loads, like with any cartridge I do, I noticed that the 32 S&W Long went from barely getting the bullet out the muzzle to stuck cases in a span of 2 grains.

This is definitely a cartridge to work up in 0.1 gr, not my usual 1.0 gr.

Hodgdon Powder has listings for H110 reloading data for the 100 gr XTP on thier web site.
Min 12.2 1419fps 31,400 PSI Max 13.2 1525fps 38,500 PSI. So far I have worked up to 12.5 grs H110 in 327 FM cases with a Federal SR primer and an OAL of 1.450 inches. No signs of excessive pressures or sticky extraction in my SP101 or GP100.

Well I have been successful with my starting loads, no issues. Except that some of the brand new Federal brass (bought in factory Federal sealed bags) had loose primer pockets, or looser than I am used to seeing and feeling. In fact one primer fell out of the case after I had charged it and seated the bullet.

I tried several brands of primers and found that Rem seemed looser, CCI and Fed were better. I even got some Wolf and they seem OK too. Maybe there was some variation in the brass...but i didn't expect that. Starline .32 H&R Mag brass is fine.

I sealed the rounds with primer sealer but I realize that isn't intended to secure them. I will fire the rounds, carefully, this weekend and see if any primers back out.

The pockets seem to measure .172 with my caliper so I figure maybe it's the angle or shape of the pocket that is an issue. I think .172 is a good measure on the pocket. Maybe I won't clean the pockets and see if some bit of residue makes them tighter, not that it would be a better seal necessarily.

Very puzzling. I loaded up another 50 from new brass and they seem tighter.....

Anyone else see a variation with Fed .327 brass, or have any suggestions on better primers? I have SR primers as well as SP but they're the same size............

Loose primer pockets are the fault of the brass, not the primers.

Any brand of SP primer should fit and not fall out.

It could be due to excess pressure of the factory loads expanding the primer pockets.

Or it could be the Federal brass was softer then it should have been.
It wouldn't be the first time Federal brass in other calibers was too soft.

I wasn't too happy to see a few primers that looked like this after firing. I'm gonna check the calibration of my scale. I loaded 12.5g H110 with 100g XTP. Only a couple of primers looked like this. I've thrown a lot of H110 with my 3BR and don't think I could have gone over the 12.5g by more than 0.1g. Certainly not enough to overcharge if the max is 13.5g.

Forty5, which do you like better the SP101 or the GP100?
