375 H&H Ackley Improved Chamber specs
I doubt anyone here can help me, but thought I would ask. If you have a referral to another forum, I can ask there. Maybe I just need to contact someone at Redding.
Thanks guys,

Re: 375 H&H Ackley Improved Chamber specs
Since it’s not a SAAMI cartridge it can be any of the improved designs. This is a 375 AI chamber:

Re: 375 H&H Ackley Improved Chamber specs
Thank you Harry, I also saw that thread before I posted. I did look around to see what information was available. That is the cartridge design. In some circumstances, the chamber is different. I'm looking for a chamber design spec as used by reamers and such.
Thank you.

Might get a hold of Manson, JGS, or Clymer and ask them if they will send you a print of their AI reamer.

Tutt, fire a cartridge and measure your chamber. If you would listen to me and leave things again it would all go better.

www.accuratereloading.com probably has the most bigbore gunsmiths logging on. Also see some fellas at 24hrcampfire talking about that calibre and 375wby on the express rifle forums

I wonder how it compares to the 375 Ruger... That cartridge seems incredibly practical for a 'big bore' high powered cartridge.

Re: 375 H&H Ackley Improved Chamber specs
Old Savage is apparently correct about measuring a fired case is the closest I can come to finding out what the specs are on my chamber since I have no way of knowing what reamer Robert used back in the day. Then I can full size a case with my Redding dies that do have a 40* shoulder and compare the two to see how close they are. There is nothing wrong with the rifle, it seems very accurate and I like to think that the case being supported by both the belt and sharp shoulder helps accuracy. I did have Robert lengthen the chamber as well so I can single shot a cartridge that is a full 0.25 longer than the nominal 375 COL. That makes a significant difference in powder capacity.
Grizz, it may not be a "big bore" but even my original loads shoot a 350 grain Matchking bullet at just under 2500 fps and I am going to be able to improve on that with RL 26 over the Ramshot powder I previously used. Its a thumper! -Tutt

For what it isn't worth, 'cause it isn't worth anything, i consider my .43Mag to be a medium bore, and the .45s to be step one of big bores. That's just me. But it makes me smile every time!
Have a great evening. Beautiful half moon up tonight.
