Ok, contrary to popular "misconception" / "perpetuated misinformation", the Colt pattern open top design ( executed correctly) is superior in strength to the Remington pattern. I've explained how/why many times before so I'll skip it here.
Find a gun you like & then contact the manufacturer.
Personally, I'd feel a whole lot better with words from the source rather than a gun forum.
I'm in NO WAY dissing this community.
The people here are top notch!
But info from the maker is lawyer proof
Besides you'll find the gun community to offer
the best customer service you've ever seen.
Can you provide any independent documented evidence, other than your beliefs, to back up your claim?
Even more worrisome I worry about the Engineers at Colt that copied an inferior system apparently not knowing they were taking a backwards step. If Revolvers without a top strap are stronger why are we still using the inferior designs today?

Surely someone must realize the superiority and offer a .500 Linebaugh Open Top.

This is the cylinder arbor for a Pietta Colt 1851 Navy and 1860 Army
Notice that small threaded end? That's what screws into the recoil shield to hold the revolver together.
When you fire the revolver, all of the chamber pressure is transferred through the wedge to the arbor wedge slot, and then to that small threaded section.
A very weak system to be sure.
Taylor's & Company New Model No 3 Frontier in .45 Colt
It might not have an octagonal barrel but I think it works well with your 1895.
Besides everyone has a Colt.
Besides it has a better rear sight and a Schofield type latch.

That is incorrect.
The New Model Number Three does not have the Schofield style latch. Both the original and the reproduction New Model Number Threes had the same type of latch as every other large frame Top Break Smith and Wesson revolver.
This is a S&W New Model #3. The latch is the dark colored part near the hammer.

Here is the latch with the barrel partially opened. The latch is secured when it is lowered over the two posts in the frame.

This is a Schofield. Notice the serpentine shape of the barrel latch. This is the only S&W Top Break that had the latch mounted on the frame. The latch pivoted back, rotating on the screw, to free the barrel to rotate down. That was the whole point of Schofield's patent on his latch. S&W had to pay a royalty to Schofield for every revolver they made because of Schofield's patent. Daniel Wesson directed his engineers to come up with an alternative style latch that would circumvent Schofield's patent. By the time production of the Schofield model ceased in 1878, they had not done so.

Here is a view of how the Schofield latch worked. When it was pivoted back, the barrel was free to rotate down. Notice the rear sight is integral with the latch.

What you are probably thinking of is that the Taylor's version of the New Model Number Three has a target sight on it. This is the target sight on an antique 44 Double Acton Top Break. The sight is adjustable for windage only by loosening the two small screws and pushing the blade to the left or right. There is no adjustment for elevation. This is the type of rear sight that comes on the Taylors version of the New Model Number Three. The revolver is also known as the Beretta Laramie.

94045, removing the "school yard" attitude from the question, I intend to do just that! Not in a .50 cal offering, but in a "modern" .45C offering, with a "wedge less" setup that will allow the use of "Ruger only" loads (not to mention the ability to change barrel lengths easily . . . sort of an 19th century Dan Wesson setup). Something a little different for the handgun hunter to take to the woods with.
For those who actually wonder what a .50cal open top would entail, a much larger cylinder, for the most part! The ability to use a smaller diameter base pin allowed a smaller package for a large bore revolver. The smaller pin along with bored through cylinders brought forth the need for a two fingered hand which allowed the ratchet teeth to be located between the chambers instead of in-line with the chambers.

I've seen open tops especially brass frame that stretched terribly and some steel frame. After talking to owners about it it was clear they were macho shooters that used way too much powder than scientifically sufficient. In my early years I had an 1858 in brass. After shooting only 20gns under a .454 ball it was showing signs. That was 45+ years ago and lots of bp gun vendors that went belly up quick back then. I also don't think the brass quality was near as good as it is now. Still I don't like brass in larger than 36cal or 44cal that shoots more tha 18gns, like a colt shorty. Although I did trade out the brass on mine with a steel from a 36 I have. Just don't like brass on 44cal.
Would love to see a 5 shot 50cal in full frame come out. Have seen some 50cal sa revolvers converted to bp by making bp cylinder, hammer and replacing case extractor with ram rod. But between the original purchase of the pistol and rework it ran around 2200. Could just shoot bp cowboy loads in it way cheaper. Still a 5/50 would be neat.
Maybe "macho shooters" with a "less than adequate" revolver? Were they shooting "out of the box" revolvers? I've set up many Walkers for handgun hunting that shoot full house loads of Triple 7 with heavy conical bullets . . . all day everyday. They don't suffer from "frame stretching" , wedge eating, arbor breaking, barrel deforming . . . It just needs to be (as any modern S.A. ) set up for the task it is intended to do.

The point I was trying to make "tongue-in-cheek" was if the top strap design didn't offer advantages I have to believe it would have been abandoned long ago.
All the more reason I prefer 36cal and regardless of caliber keeping the charge at the low to just under mid volume.
Yes, but my question is would the Walker have to be the size of a BFR to handle that load if it was a different design?
Save trolling for twitter.If I was that scared, I'd just give up cap guns period!! You're a brave sole!!

That "small threaded end" is right at 5/16" (course thread) and has a tensile strength of roughly 4,000 lbs (for low carbon mild steel).
It isn't just the tensile strength of the threads of course. It's the tiny area of the recoil shield that the threads of the arbor is pulling against when the revolver is fired. Such a small area to withstand all of that chamber pressure is far less than with top strap revolvers.
According to the Lyman BP Handbook Edition #2:
- a .44 caliber revolver using a 200 grain conical bullet with 30 grains of GOEX FFFg produces 8100 PSI.
- the same revolver using a .451" round ball with the same charge produces 6500 PSI.
That's significantly more than the 4000 PSI maximum pressure that that you believed would occur in a cap & ball revolver.
Also, you appear to have forgotten that in your post #21 you stated that open top revolvers were better for conversion cylinder smokeless powder shooting because (in your opinion) they were stronger than solid frame revolvers.
According to SAAMI standards the maximum standard working pressure for mild factory .45 Colt loads is 14,000 PSI. Even if most of them actually only run around 12,000 PSI, that's 3 times greater than the 4000 PSI maximum that you believed that a C&B revolver would experience.
You believe that 12,000 pounds of pressure yanking at a 3/8" length of 5/16" diameter threaded rod is stronger than a solid frame? I hardly think so.
And you still haven't provided any of the documented evidence (other than your own opinions) to substantiate your claim.
Why would every single manufacturer of revolvers have abandoned the open top design if the top strap design was not stronger?
Would any manufacturer have been able to successfully produce powerful smokeless powder revolvers otherwise?
Wow!! Are we all over the place or what?!! Lol
Ok! I count 7 paragraphs so I'll just answer them in order. Here we go !!!
P1- Hey! You're right, it's screwed into the bigger/thicker (and fully (meaning all the way through)) recoil shield of the open top frame! It's anchored in an excellent foundation (torqued too!)!!
P2- I know !! Right?!! This makes you wonder how a Walker could stay together with twice the charge (which would be 60 grs.) of Triple 7 (even MORE power!!!) After all, a Walker's arbor isn't that much bigger than an Army/Navy arbor !! How's that work?!!!
P3- (They are! We're just rehashing the same ol stuff here . . .)
P4- You are free to "hardly think" anything you want!!
P5- I don't really feel the need to have to provide "documented evidence" for my position ( you didn't . . ). I've already told you about bending the Remington frame when loading but actually shearing a screw (takes a pretty fair amount of force to do that!) while loading an open top! If you understand the difference between those two events, it's pretty much self explanatory. (Besides, it's the Internet and you ain't my daddy . . . )
P6 - Ugh . . . cheaper?!!! I already explained the smaller package thing and the need for a 2 fingered hand , blah blah blah . . .
P7 - Of course!!! Here again, I've already mentioned about a Dragoon based revolver, wedge less, shooting .45C Ruger only loads . . . remember . . . ^^^^
Anyway, you seem to have a disconnect about the difference of the strength of a pressure vessel (cylinder) and the structural strength of the support for the vessel.
Here's one for ya to think about . . . my 5,000 lb car is held off the ground with 120 psi of air !!! (30 lbs psi in each tire!!) Holy mackerel!!!!
