I'm wondering what new developments have been made in regard to 32 fed mag handloads. Appears that many guys are deep seating heavy bullets to fit single six cylinder length. But it is apparent that full size Blackhawk guns can handle a stouter load with ease and the heavy bullets can even be less deeply seated than the crimp grooves. I've accumulated brass, bullets, and dies to start testing out my new 327 8shot Blackhawk. Fermin is making me a new front sight and Bowen target rear is on the way. This should be fun!

A couple of Ruger 32mags fell in my lap within the last year. Am not sure how I survived all these years without one ! Playing catch up now. Reading or re-reading threads here. Good stuff guys, thanks.

Good stuff guys, thanks. If they are the older units they will need cylinder correction before you can get the best out of them. They are capable of astounding accuracy once you get them right. You know where to find me if I can help.

Yup ! Believe we talked or messaged or something ...about the Single-Six cylinder possibly heading your way, sometime. Life got busy.

Well, my search for the perfect load continues with the .32's.
I just reread this thread for the third time and I seem to always learn lots of new stuff. My 32 auto, 32 SWlong, 32-20, and the 32 H&Rmag have done well. It's the 327 that still eludes me for great accuracy. Obviously, some folks have discovered the right recipe of gun and cartridge.
I contacted Vihtavouri about supplying some load data for the .32's and they gave me the old run-around big time. Don't hold your breath. Their rep said several VV powders should do well; but refused to give which ones or numbers. I asked him if he thought that it was irresponsible to encourage handloaders to use VV powder for a caliber VV wouldn't supply load data for. He said, "No comment".
We're still doing extrapolations and experimenting. Start low! Duh.

I understand starting low, but my experience with 327 fed mag suggests that if the primers are not flattened to some degree, the loads will not shoot any good. My one 327 is 8 shot Blackhawk. My best loads are coated cast bullets. The #1 best is a NOE rnfp 120 gr pc over 10g of 2400. Standard pistol primers. Best load #2 is 9.5g 2400 under sledgehammer no lube groove, pc. This load tightens up with small rifle primers. I've tested a dozen powders and another dozen bullets. Sizing is very important, my bullets cannot be pushed through chamber throats without pretty good amount of force. I actually purchase both of these bullets from forum a member.i also figured out from reading Brian Pearce articles on the difficulty of loading 327 that the crimp needs to be just right and really fill the groove. Fermin loves h110 with the heavy slugs but my gun seems to run 2400 better. Obviously I get less horsepower but with the accuracy of my gun, I can hit what I want. I think every 327 is like getting a new puppy. Each has to be figured out.
I bought lee 314-90 swc mold to try. Have a few loaded up with unique. Mild loads of any quality of eluded me. I managed to run the fp mjolnir bullet with 6.5g herco pretty good. But not amazing.
I've also found that loads that did not originally do well, now do fine. After putting close to 1000 rounds through this gun, I think I am starting to understand it, but it still bewilders me at times. I got lazy loading 38 and 45 colt standard loads. The 327 has forced me to be better at wielding my gun, better technique at the loading bench and more patience. It's been a lot of fun.

The 327 has forced me to be better at wielding my gun, better technique at the loading bench and more patience. It's been a lot of fun. Fermin and I became friends over 32 mags 15+ years ago. We compared notes and cast bullets for years and I have run a lot of 2400 and H110 for heavy loads but I admit that Tank Hoover had me try out AAC#9 and I have fallen for the stuff for my heavy 327 loads entirely, enough that I bought a 8lb jug of it! Consistently higher speeds than H110 with lower velocity variations by a bunch, just run standard small pistol primers instead of magnums. I have gone past 1600fps easily with 100gr bullets in my 327 S7 Bisleys and the cases push out with the slightest press of the extractor rod! HS6 and Power Pistol are fantastic for mid range loads and W231 for mild target/small game loads if I intend to eat the game. YMMV gunblast.com/Freedom-Harton327.htm

Hey Professor,
The Blackhawk 8 and a Single7 is what I am shooting for the 327fm. I've used 2400, HS-6, VV N340, 4227, BullsEye, 231 and just loaded some #9 to try; but I don't think it's the powder. I'e tried 6 different bullets; but they have been 115gr and up. At 25 yards bench rested, I expect a 1" or better group as normal. I was seeing 3" with the BH8.
I pin gauged the BH8 cylinders at .314 and the bore looks to be the same .314. I haven't slugged the bore for the groove diameter, but I assume it's .315 or larger. I think I'll try that today.
I have a couple of .314 bullets, but I think .001 to .002 oversize is the best fit for the groove; which I think means I need a .316 bullet. I haven't seen any signs of leading in the barrel.
I don't think even 2Dogs could fix these dimensions.
Did I miss something?

I have no idea why. Since I have mine shooting good, I'm thinking of buying another and sticking with the Blackhawks rather than dealing with loading separate 327 cartridges for other guns.

As I recall, my Single7's cylinders all pin gauged at .314, just like the BH8.
Interesting posts about running the 327 with hotter loads (flattened primers) for accuracy.
I may need to bump my loads up to try that out. I think I'm runnning around 1300fps now.

I may need to bump my loads up to try that out. I think I'm runnning around 1300fps now. Prescut Work up carefully. A know a fair number of S7 guns have tough chambers and really stout loads can be a bigger to extract. My stainless S7 Bisley has 3 rough chambers, 4 charge holes extract smoothly and 3 allow the case to extract 1/4” and then they seem to hit a ring and just stop. I don’t have that issue with my other 32/327 guns. Probably need to have the chambers polished properly. But the point is I can’t run as stout of loads in it as I do in my other S7 327…

Fowler,
I thought it was just me who got a s7 with 7 rough chambers. The brass formed to the chatter marks and I couldn't extract without mechanical assistance. It was the worst chambers I had ever seen; and the fit and finish wasn't much better.
My S7 went back to Ruger and came back polished; but with .314+ chambers. How can Ruger do that with a smile and a "that meets specifications" statement?
It makes matching cylinder holes with groove diameters difficult to impossible.
Is it possible to make the BH8 .314 coming out of the cylinder "expand" into a .316 groove? I doubt it. I'm guessing they rattle down the barrel from side to side with very little spin. Would anyone possibly ream cylinders to .316 and then make .316 bullets? Those might obturate and fill the groove?
I chased my tail for a year with a S&W 25-5 with giant chambers. I really don't want to do that again.

I haven't been able to work up a load with a .315 bullet. Factory ammo works(at least matches my ability to shoot)but I plan to try powder coat to get my cast up to .315.

Thanks for the post Alamogunr.
I'm trying the same thing with powder coating.
Have you slugged the barrel to find groove diameter?
