Strength of replica model 1874 Sharps

I would like to hear opinions on what folks feel is the safe strength limit of a modern replica model 1874 Sharps.
To make this simple because we already have established three different pressure levels for the 45-70 cartridge let us say that our replica model 1874 Sharps is a 45-70.  Would it fall into,
group #1  Springfield trapdoor
group #2 lever actions, 1895 Marlin & 1886 Winchester
group #3 Ruger #1 & #3
Tell me what you think.  Dont worry its not a gotya question.  I will kick it off by saying my opinion is group #2

I’m assuming you mean an Italian replica?

I rate them all about the same imports or domestic. All are made with modern steel. I would not include original vintage rifles in group #2

I wouldn't and don't hot rod any of them. I shoot them for what they are and how they were designed. They may be made from more modern metals but the inherit design is the same. If I feel the need for more powerful firearms I will go to my bolt guns. My two cents......

I believe most reloading manuals put the 1874 Sharps in group #2 but I don’t have any in front of me right now

If you’re confident that the imports and domestic replicas are the same, C Sharps will chamber you one in 375 Winchester or .500 Alaskan. 

Pedersoli lists load limit in their manuals, Commercial CIP pressures around 30,000 and hand loads using Lyman data. That puts you squarely in the #2 class. If I remember right CIP proof is max plus 40%.

I've had a number of Shiloh rifles; the earliest was built in 1986.  Early on, I thought smokeless and heavier loads was the way to go.  It didn't take long to realize that, when loaded to heavier loads that were still safe, the rifle was not enjoyable to shoot.  Recoil with a 400 grain bullet at ~1700 fps was much more than I wanted to endure.  I switched to black powder and never looked back.  Black powder loads can be shot in shirtsleeves.

Kirk says his Shiloh's will handle anything a Ruger #1 would.  I've only ever shot black powder with mine.  When I was younger I used to like shooting jacked up loads from my Ruger, but it eventually knocked some sense into me  Cheesy

I remember reading that. I was surprised by it. I don’t know why anyone would want to magnumize a Sharps rifle. I guess it’s good to know the strength is there. 
I shot a buffalo with a 510 grain lead bullet and 65 grains of Swiss 11/2. The buff went maybe 10 yards and expired. The bullet was still going. Can’t imagine needing more energy.

If you need a little more energy all you need to is support your shoulder with a big stake or fence post. If the shoulder can’t move then all that energy will be transferred to the bullet. Probably enough for 75-80 fps velocity.
