Three Colt Walkers - Conclusions and Results
Вставка
- Опубліковано 23 кві 2024
- Tried to summarize what I felt were main results from shooting two Uberti replica Walkers and a Colt 2nd Generation. More details can be found n the videos of shooting the individual guns. THREE COLT WALKERS - parts I - IV.
Great video and information 👍🏻
Thanks 👍
Thanks for the info Old Ranger. Good video, and Thumbs-up ~John
I wouldn't have expected such drastic changes (or any changes really) to the twist rates of the Uberti barrels. Interesting.
Me neither. O.R.
@@oldranger3044 I recall reading that the original Walkers had a progressive rifling twist from 1x24 at the breach too 1x18 near the muzzle. I might be wrong about the numbers. Memory is not what it used to be.
@@johnndavis7647 Well that certainly makes sense. I’ve never stumbled across Walker info, but many including Elmer Keith talk about the progressive rate of twists in those early style guns. It’s amazing to me that their cylinder arbors taper where they enter the barrel. Their machining was not to be underestimated. They had reason to attach shoulder stocks to the dragoons. Their accuracy might have rivaled many rifles. Keep safe this summer. O.R.
Interesting about the varying twist rates, I have not measured my 3 Walkers, but they are from different years, 1 is a second generation, so they may also have different twist rates, I use .454" balls and they all shoot very well. Stay safe! Chris B.
I’m betting 1-60 for your 2nd generation, their 1860’s are the same. So is my 1860 ASM. ASM was also making the Walker during that time (I believe). Somebody rifled the barrels, and maybe it was Colt,,, and maybe not. I really need to compare the rifling of the 1860 Colt with that of the 1860 ASM. Keep safe Chris. O.R.
The Walker is one of my favorites.
I have seldom been without one these last 40 years.
I have had three of them. Not all at the same time though.
I shoot 451s in mine. I get chain-fires if I forget the lube.
454s might be better. I do get good accuracy with 451s though.
I have often thought what a nice gun it would be if I installed a loading lever and catch from a Dragoon on it. I know I'm not the first person to ever think of this. Some gunsmith 150 years ago probably did exactly that or cobbled up something similar.
Thanks for the video
Thanks for sharing. I was especially cautious about the lube in the 2nd gen Colt. I wouldn’t be surprised if anyone with a ASM Walker would also have a slightly larger set of chambers and would experience chain fires with a 451. Thanks again for your input. O.R.
I would have suspected that a slower twist rate would slightly increase velocity as the ball is having less force imparted from the rifling. Aggressive twists are more forceful. I'm certain that this thought has already occurred to you but maybe with undersized .451 ball, there is much more gas blowing by inside the slightly larger chambers of the Colt 2nd Gen. In any case, I wouldn't have thought that twist rate would have affected velocity to that degree, but occasionally, my minds eye and logic disagree with real-world results and I'm just wrong. I would certainly be curious to see if .454 RB used in the Colt would bring up the velocity. As usual a clear and concise video and I will await further developments. Still haven't test fired my 3rd Gen with the new front sight but hopefully this weekend I'll go out to the range at Wateree and see how she prints. Thank you sir.
I would think the same, and did. However I plan to check into this more. What I may have miss reasoned is that powder (and maybe especially black) does more than give the projectile a quick ending sudden jolt. I have fired using only the cylinder (no barrel), and the speeds are about half. Sooo, it’s burning and accelerating the bullet for a time interval. If you’ve ever ignited a small amount of black powder or smokeless for that matter, it seems not to really explode, or have all that much energy. Something different happens under pressure. Sooo, possibly the faster twist changes the burn rate, equation, or whatever, causing more pressure, hence more speed. Hows that for a theory. O.R.
@oldranger3044 Yessir, I believe you just referred to the powders "specific impulse" which is an engineering calculation that describes how much power a given volume of propellant, gas, fuel, or explosive can generate over a specific amount of time. Black powder burns relatively fast compared to the substitutes, but all of them work best in a longer barrel ( but not too long of a barrel), i.e., over 40" possibly. You are definitely on the right track, I believe, and perhaps in a certain way twist rate does affect velocity as a faster twist will require more pressure exerted on the ball to pass through the rifling than a slower twist, and thus a longer specific burn is achieved. I thought about this very same thing yesterday afternoon while I was out on the back porch with my own pistol (it has gain twist but I'm not certain of the rate) and it occurred to me that yessir, it is certainly possible at least in one way that twist rate can affect velocity. Sometimes, when I'm commenting on a given topic, I miss the point entirely as I'm just trying to solve the issue as men are geared to do I'm told and I realized that in commenting that I was on the right track but the wrong damn train. I do think you are correct and proving it out will not be too difficult.
Just a quick note that one way or another may be playing with the velocities of the 2nd generation. Bore size. As you have mentioned the .451 didn't shave any lead on loading. I recently slugged the bores on two Remington new model Navy's. One from peitta and the other uberti. The reason was I did was based on the measurements of the cylinder in the development of my conicals, render the idea of a .375 diameter bore made zero sense. The uberti slugs @ .371, and the peitta @ .3665. So slugging the barrel maybe worth while .

That's something I should check into. Thanks. Another viewer wanted me to check cylinder gap, which the Colt turns out to be the winner with as I remember about .015 compared to Uberti newest model at .003. O.R.
Hello, I enjoy watching your videos. Is the cylinder gap on all three of these revolvers the same?
Also on your comparison video for lubed wads versus lube on top of the ball. Have you tried putting a thin card between the powder and the wad? That would keep the lube from absorbing into the powder. In theory.
Ok, I think I know where you’re going on this. Hang on to your tool belt I’ll be right back. Ok, so I temporarily forgot where I stashed the 1-16 twist, but found it. .003. The colt (1-60) is.015. My 98 (1-30) is .007. All are as found after cleaning and I suppose could change some depending on the wedge tightness, but probably not lots because of the taper fit.
I believe I did. Also have tried the card between ball and wad to keep wad from cementing to the ball (if it does). I’ve evidence to support that because of finding wads in the sand back of the targets. I don’t remember details of what happened with disk over powder, but assume it didn’t impress me, or i would be using up my stash of felt and SPG. Thanks for your comment. O.R.
Did you try 454 balls yet
Don’t believe I have, well, maybe in the 2nd gen Colt. O.R.
OR: Do you plan on doing the same thing with conicals?
That would be interesting for sure, but then there would be the issue of which conical, and whether I’ll live that long. 🤔. Great idea however. O.R
