Wanted; 327 mag loading data

[contender]

Since it's a newer caliber, I'd like as many different ideas y'all are using for reloading the 327 mag. Both with jacketed bullets, and cast.
Lets see your pet loads!

I have had the best luck so far with my old lead bullet standby powder, Clays. The load is with a 115gr RNFP cast from WW with a little tin added. The load is Max from the Hodgdon manual at 3.7gr Clays. Standard small pistol primers were fine.

Velocity is an honest 1,000fps from my 5.5" BlackHawk, 950 or so from the GP100 and 900-920fps from the 3" SP101.

I tried the Longshot powder with 100gr. XTP. I got very erratic velocities from the 12 rounds I loaded for testing from 1275 to 1400. :? There is a sweet spot somewhere there but more testing will be required. I'd like it to work, as it is the most economical powder for higher velocities.

I want to work with Titegroup some and Trail Boss. Anyone else have results yet with 327's?

Thanks for the thread idea Tyrone.

Eric posted a link to M D Smith Reloading pages I have had some nice loads from there. Haven't done anything with the 327 Yet. ps

I'm shooting a Blackhawk. I've seen 1800fps over the chrono using AA#9 and 85grxtp. CCI 500 primers. I started at 12gr and worked up till I had a case split. I never had sticky extraction, just a split case. I stopped and backed off .5gr. Heck, those little brass cases are hard to find and expensive when you do find them. FA helped out with a couple hundred awhile back and that's what I've been using for load development.
Some others I've tried with good accuracy.
H110...13.5gr....100xtp...1350fps
2400...12gr.......100xtp...1250fps
AA#9..11.5gr....100xtp....1200ish fps

Next are some cast from a custom mold (thanks 2dogs) 313640 118gr. There is a lot of combo's with this mold. I have 3 different HP along with the flat point, plain base & GC. Then there's lubes, CR, BAC, Speed Green & Speen Green C from Bullshop. It's going to be a long drawn out process. But a fun one.
Best accuracy is 10.5gr of 2400 using a deep hollow point w/a plain base & Speen Green C lube. I cast using wheelwheights & linotype, 3 to 1. I size to .313. My bore is a .312 and the cylinder throats are .313, just right, from the factory even.
So far I'm having the best accuracy using 2400. My accuracy standards may be different from others. I shoot off hand, no scope, no red dot, no rest. I want to know if I can hit what I'm aiming at in a field situation. If I can get a 2" group at 25yds, I'm good.

Speer has 327 Federal loading data in their website. I just printed the page off the other day. It only includes their Speer 115 grain Gold Dot HP, though.

Reloader mag had some 327 Federal and 32 mag loads in an issue not too far back.

I haven't started loading for the 327 yet; only 32 mag to date.
