My brother has a repro Walker made by ASM, I believe. Some years back we decided to see how much powder we could cram in the chambers and got about 62 grains of 3f GOEX in each, near as we could figure. Fun to shoot, lots of smoke, not bad recoil, but each cylinder-full consumed over 370 grains.
A friend of ours, who is an excellent pistol shot, was regularly hitting a playing card-sized target at 50 yards using a 50-grain load in the revolver.
All-in-all it was a lot of fun but my brother sort of christened the Walker "Powder Pig". Can't say I blame him.
That's why we need Mike.whughett is correct. A Walker with a corrected arbor will be perfectly fine with "full house" loads. The problem with all " horse pistols " (and most cap and ball revolvers ) of any make is that they have arbors that don't bottom out in the arbor hole. This is what keeps these revolvers from beating themselves to pieces.
The "fellow who hunts hogs" with them may be Hovey Smith who also hunts deer with the Walker as well. His "hunting" Walker is known as the "Super Walker". I set the Super Walker up so that he could shoot full loads of Triple 7 along with Kaido's bullets.
The arbors in all of Colts open top revolvers are screwed in and staked, not pressed in.
The reason the arbor must bottom out in the arbor hole (under tension) is to transmit energy throughout the arm as if it were one piece. Otherwise, the two assemblies will vibrate at different rates and eventually destroy each other. It's a harmonics thing.
Anyway, as stated, correctly built and or " fixed", they work as designed (as did the originals) and will last.
As a side note, as far as I know, Pietta is the only manufacturer that has addressed this problem (since around 2008-9). All other open top revolvers I have ever worked on have had short arbors. That includes the cartridge conversions/ 72 open tops by all makers (except originals from Colt of course!!)
