Did I overload .327 FedMag with 4227?
I loaded 20 rounds of .327 Federal Magnum with 11.5gr of IMR 4227 and a 115gr Badlands FN boolit. The powder is slightly compressed.
That load is fine (according to published data) for a 100gr boolit but after loading I realized I did so with the 115gr.
Is this safe to send downrange? Shooting a 4.625" Ruger Single Seven. Thanks for your advice!

Lyman’s 50th shows a compressed max load of 12.3 grains of 4227 under a Speer 100 grain JHP giving 1214 fps and 33,600 psi.
They list their #311008 115 grain cast bullet over a max load of 11.7 grains of Accurate #9 with 1436 fps and 43,600 psi.
Primers are Federal 100 SPP. Test barrel is 3”, universal receiver.
If it was my Blackhawk...I’d shoot it, and make Elmer proud.

If you give me the case length, bullet length and cartridge over all length I can run it in Quickload. I don’t trust the predictions for straight wall cases like I do w/ bottle necks but we can call the prediction a sanity check.
I ran it w/ some of my data for the same pistol. Case length - 1.200 / OAL - 1.510 / NOE 315-115-SWC which is 0.655 long.
PMAX is 31,527#, slightly below warning, at a velocity of 1200 fps. 11.5 grains is 110.5% fill if the case capacity is 19 grains of water. You’re not going to get an OAL longer than that. It’s the absolute max I can squeeze out of any of my Single 7s.
