Hello all.
So I picked up a NOS Lyman 358627 which got me to thinking.
Can I run this in my Uberti 1873? I know it’s built to handle a lifetime of 357 magnum and there’s guns that have done just so. No manufacturer in their right mind would advise using their rifle with loads that would wear the gun down in no time flat. Never mind possibly causing damage that would result in a law suit.
Which got me to thinking about pressure vs bolt thrust.
I know the 357 magnum is loaded to more than double the pressure of a 45 Colt. However how does that translate to bolt thrust? The pressure is held within the case and the chamber right? Bolt thrust should be the main factor when it comes to damage to a toggle link action right?
So how does a 255 grain 45 colt bullet loaded to 14k psi compare to a 215 grain 357 mag bullet loaded to say 30k psi? Vs a 158 grain 357 loaded to 30k psi?
Am I thinking about this properly? Which has more bolt thrust?
I know that Uberti also makes 44 mag 1873 rifles now. Though they only appear in blued actions and not case hardened which has always made me wonder if it’s a different steel or heat treat used for those actions alone? I’ve searched around a ton and can’t find any info to prove or disprove that.
All my research shows that bolt thrust discussions are one of the top 3 ways to start a bar fight. Some people don’t believe it exists. Some do.
So if it doesn’t then does it matter what bullet weight I shoot as long as I keep it under the 357 magnum pressure limits?
That being said I think I would stick to some light plinking loads with this bullet in the 73 because I really just plink at steel anyway and the extra weight should ring it like a bell.
Thanks for looking all!
