I went down a little bit of a rabbit hole reading and the stumbled upon something that created some question. I have a Freedom Arms 97 in 327 that shoots way better than I do with a max load of h110 and the 100 grain XTP. That charge of 13.2gr came from the Hodgdon website. It's a laser beam in terms of trajectory and it also shoots little bughole groups at 25 yards (when I do my part). I started looking at an article about Freedom Arms which then led down this rabbit hole where I started bumping around all the different articles Jeff Quinn had done on the various Freedom Arms revolvers. I read that article many years ago but when I read it again today I was quite interested in the load data that he posted. The article dates back to 2008 and in the article he does say that there was little to no pressure tested data available so he was on his own. His maximum charge of h110 is 16.5 grains of h110. And he even used that same charge for a few other projectiles up to 120 grains. I have no doubt that the 97 can take it. It's probably much like the model 83 357 given all the meat around the chambers. I then went to the Load Data site and almost every charge there maxes out at 13.2 grains of h110. The Hodgdon website says that max charge results in 38,500 PSI. The max pressure for the 327 is 45,000 psi. So all this leads me to a question for those of you who reload for the 327. What is your maximum charge of h110 for a similar projectile? I'm really curious what his load of 16.5 grains would result in when pressure tested. I don't question the revolver but like the 357 in the model 83 I'm guessing the brass would be the weak link. He was shooting that load in both the Freedom Arms and a Alan Harton built revolver. The velocities for both were around 1600 for the FA and 1700 for the Harton.

My load for the 327, and 100 gr xtp is 13 gr H110, not sure the 16+ gr would fit in the case, probably highly compressed if it does, this is in my Ruger single seven

Well I know the article and stomped on some reloads very close to those with my S7 and yes they are real. I was able to fairly easily get 1650fps plus from XTP or MIHA 360640 100gr gas checked bullets. The accuracy was great, the muzzle blast brutal, and brass life a bit rough.
I have found for max performance loads in the 327 AA9 is a better powder AND you really want to run STANDARD primers. AA9 gave me more velo with less case stick, and lower SD plus going to standard primers did the same without reducing velos as well.
Now all of that being said for 100gr weight class I have found Power Pistol and 1450-1500 a far better combo. Better accuracy, brass lives forever and all but falls out of the gun and does all I can ask a 327 to do. Honestly my normal load for the 100gr MIHA is about 1250-1300fps, just more fun and less muzzle blast.
A heavier all round load is a 130gr LBT solid at 1350fps over AA9 powder.
Standard primers reduced variances noticeably with every bullet and powder I tested. Funny Pearce wrote an article a year later confirming all of the data I had found as well. Regardless of the powder chosen, the case is narrow and you are not really trying light much powder when you do shoot so you just don’t need the heat of the mag primers. I mean I had H110 loads that had SD125 variances drop to 15-20 with standard primers. Not something you notice in target at 25 yards but try and shoot 75+ and that sure shows up on target.
Good luck and let us know how you load development goes.

That's good info. Thank you.
I have learned something similar with primers and the 22 hornet. Standard pistol primers are all that's needed because of the smaller powder volume.

That's good info. Thank you. I have learned something similar with primers and the 22 hornet. Standard pistol primers are all that's needed because of the smaller powder volume. When I got my first .32 H&R single six, I had a real problem with pierced primers, I switched to SR primers and never looked back. My loads were near max but not the Max Keith loads popular way back then. In my falling black, I was loading 13.7 grains of H110 under 115 gr bullets seated too far out to fit a Single Six cylinder (rifle only loads). My Single Six loads were much more sedate as the revolvers were pretty scarce back then. |

Thank you. I looked for it and wasn't finding it. |

Thank you. I looked for it and wasn't finding it. I bookmark threads like that cause I have the same problem…… |
