#3 first. Check out forum rule #10. We do not discuss metallic cartridges or conversion cylinders on this forum. While I understand your opinion on this subject, like I said before, I personally could not care less about them or the use of them. BP with round ball or conicals in paper cartridges only. And it's the forum rules.
Concerning Remington replicas, no I don't know for a fact Pietta is better. My sample size of 1 Pietta 1858 in my collection is not enough to form a solid opinion. However it is a great shooter with a smooth action compared to Uberti 1858's I've shot and handled. When it comes to Colt replicas, yes generally speaking Pietta is superior out of the box comapred to Uberti.
#1 Forged is not ALWAYS better than cast. There are too many variables at play to make a blanket statement like that. However in the ever on going debate of Uberti vs Pietta, I will agree that if comparing similar models, Uberti frames are ultimately stronger.
That said, Pietta frames are certainly strong enough for a long life with BP and sensible loads. If someone insists on cramming as much T7 into the chamber AND still being able to seat a heavy conical, then the Uberti will likely be the better choice. However MOST cap and ball shooters do NOT do this.
Pietta's MIM parts does not bother me in the least. Most unmentionables actions these days are comprised wholly of MIM parts. Seems to work just fine for them. Pietta's also seem to generally work just fine out of the box. Could they be improved by tuning, well sure. But they work well out of the box for most folks. Uberti's seem to need work to function well. They certainly look better. I'll give anyone that. Most folks will NEVER have their revolvers tuned, so the whole idea that Uberti's are easy to tune than Pietta's is lost to MOST shooters. If you are a competitive shooter then tuning I would imagine is something that IS very important to you. Most folks just want to plink, informally target shoot, or hunt. And they want the revolver to work right out of the box to a reasonable standard without a further outlay of cash to 'fix' imperfections in the action. Pietta's fit that bill perfectly.
Well sir, I'm sorry you took it personally anyway. You admit that you're not an expert and have a whole example to expound on. I'm not claiming to be an expert but I've tuned a few hundred of them so . . . I'm familiar with them.
I doubt Pietta uses a casting process the likes of Ruger so I'll defer to the forged product for "upper end" testing. Of course both manufacturers products are perfectly fine for black powder. The op was wondering if the Uberti was worth waiting for. Obviously a question of differences in the two.
The thing about the MIM parts and being thick can be seen in another thread concerning a first time broken part.
And just for the heck of it, the op asked about "conversion " cyls and you decided to let him know you don't care for them in the least. Folks here for the most part know all my bp revolvers are conversions and I use them as test beds for the "platforms" they're in. It's an excellent way to do so since one can fire max bp loads in any of the offerings.
So, that makes me the 3rd one to mention the "you know what" cylinders so I'll try and control myself in the future.
