45 Auto Rim

[Dusty Tagalon]

Simple, any banana grip Webley OK.
I doubt anyone can see difference between an unaltered Mk4 or Mk5.
Problem is shaved cylinder/45 autorim! In all honesty, I can spot a shaved cylinder without a side by side comparison.
All I am asking for is clarification. I show up with a Mk5 with shaved cylinder shooting 45 Autorim, leagel or not. If not, is it Mk5 or shaved cylinder is the problem? I don't possess an unaltered MK4 or Mk5 for comparison. This "SOF" (stupid old fart), only seeks clarification. I want details, Mk4 vs Mk5 cylinder dimensions.
2nd, in all honesty, I can spot a shaved cylinder without a side by side comparison.
My thoughts, unaltered Mk5, OK.
As much as I would like to shoot my shaved Mk5 in NCOWS, I shouldn't! Although it would be safer to shoot in autorim, my Mk5 has 2x strikes against it, Mk5 from & autorim from 1915.
I want to know cylinder dimensions of Mk4 vs Mk5 before I call to ban Mk5.
2nd issue, shaved cylinder! In all honesty, I can spot a shaved cylinder without a side by side comparison, therefore as much as I would like to use my shaved Mk5, it isn't an NCOWS gun.

Uncle, I give up, if you can't understand my reasoning, stick the fork in my butt, I am done!

Might want to 'tap the brakes' a little Brian. There are people working on this issue even as we speak. See you at the Ruckus.

I am stepping back.
Also, from here on out, pledge not to post while under the influence!
Please let this drop for now. I have embarrassed myself enough here.

Good idea.

Dimensionally, the .45 Auto Rim is nothing more than a Webley MK 1  case with a thick rim.  I suppose it depends on how far into the weeds you want to go.  I would consider it far closer to the Webley round than a Ruger Vaquero is to an SAA.  FWIW (not much at all I'm afeered!    )

I usually fire my 45 Auto Rim thru either a 1917 Colt or S&W and then reload with black powder for my Mk V. I have a Mk IV, Mk V and a Mk VI, but only the Mk V was shaved, the older and newer Mk's are still both in .455.

[Dusty Tagalon]

Shaved 45 Schofield down to 477 length, 50 rounds fired so far, all went bang, no primer blowouts! Rolling forward with tests. For the most part, safety sake, 45 autorim is safe, chopping brass down to .455 length isn't. So far working, but possibly not the safest.
My smokeless load, .5cc green dot, 200 gr bullet, little to no recoil, hits targets hard. This Mk5 will be my primary weapon, challenge/DQ me, I don't care!

Thinking we split hairs pretty close with this topic of cartridges. Many of us use a cartridge case in one or more of our firearms that is headstamped different than the arm. Examples abide everywhere such as 45-60, 40-60, 45-75, 50-95, 44 Colt, 38 Colt, 44 Russian are just a few examples. Sometimes were starting with an approved cartridge, other times, no. Pull out the book of cartridge conversions for an interesting read.

I'm not sure I agree with your examples of the head stamps. I shoot all of those calibers (and more that are obscure) and the only one I have that has a different head stamp than the caliber it is being used for is 44 Bulldog - that casing has been out of production since the 1940s. It is a turned down 44 Russian that Buffalo Arms makes. I will grant that at the moment, with Jamison/Captech out of business again, the brass theWinchester 1876 calibers is tough to find, and expensive. Quality Brass makes them about once per year. Bertram in Australia makes some of them, but they are really expensive. But with 44 Colt, 38 Colt, 44 Russian brass plentiful and pretty inexpensive from Starline, I don't know why anyone would be using an improper stamped casing for these.

Reading this has left me with a question about .45 AR revolvers. I have a New Service made for .45 ACP/AR, not a 1917, this was a commercial gun built in the 30s. If AR were approved, would my gun be legal for NCOWS?

Probably not. The proposal written for Congress to vote on specified approved original revolvers that were modified by shaving the cylinder. Is also specifically excludes the use of 45 ACP with moon clips, which later revolvers were designed to use. Such modifications were typically done to revolvers that were originally chambered for European 45 caliber cartridges that had thin rims. The cylinder would be shaved for (originally) 45 ACP and moon clips.

As an aside, it seems to me it would have been easier to just rechamber the cylinders to a US 45 caliber. But, the main reason it was done was for the war effort of WWI, when production of 1911 pistols could not keep up with demand, but the Ordnance Department had plenty of 45 ACP ammunition. The 45 Auto Rim was developed in post war 1930 for the modified revolvers as well as the models of 1917.
