First of all, they are called .44's as that is close to the bore measurement. Groove to groove, they are all .45's.
The .36 models, mostly shoot .375" balls. My bro uses .380's in his pair of 51's that he used in cowboy action shooting.
He had to go to slugs in them to get them knock over the plates needed. He's worked on them and they are VERY accurate.
The Uberti "Colt" revolvers are likely the best of the repros. An 1851 is a .36.
The 1860's are the Army .44's & usually are decent shooting revolvers, but can use some help, note below.
The Uberti company made some civilian model 1860's that had a fluted cylinder. I had one of those for a while. We (bro and I) bored out the cylinders to .457" accept a .460" ball as the barrel's grooves were .456". As the gun came from the factory, as are most of the replicas, the barrels groove to groove measurement is larger than the cylinder holes. This modification made them (the Walker and the Army) shoot better than about any modern revolver that did not come from a custom factory.
We were shooting sub 2" groups at 25 yards with them both.
Also, the Remington 1958's I have no experience shooting, but some like them. Not many people corrected the cylinder/barrel groove problem or even know about it.
I think the Walker .44 is a model of 1847. They ALWAYS drop the lever, every shot from recoil. The design of the post/spring keeper is a poor design. Taylor's was very accurate after the modification. Just a few years back, he managed to buy it back from the widow of the guy he sold it to, decades ago.
The Paterson (note the spelling) is a .36 seems to me. It is pronounced Pate er son, not Patt er son.
Most everyone makes that mistake. Old Lester H. Hawkes corrected me on that. He had one (original) that was a very "good shooter".
I should add here, that Les said it was a very good aerial shooter. One day I was out at his "diggins" and had my service revolver, a 5" model 10 S&W. We did some aerial shooting with it and he taught me how. What a blast, shooting hand tossed chunks of coal.
A few years later, I taught Taylor how to do it with our service revolvers, out at the Squamish, B.C. range. The easiest gun of all for that was the Ruger 4" .22 Semi auto. It was just a natural pointing pistol. I suspect a 1911 might also work well, but never tried one for that shooting. Sorry for getting off topic.
