Pressure levels for a NEWER Shiloh Sharps

[358Scout]

Considering getting one in 45-70.

I have a Marlin 95 which is rated for Level 2 loads, the Ruger #1 is rated for Level 3 loads.

Can a Sharps take a Level 3 smokeless powder load ?

your safest bet would be to maybe contact the people who built the rifle .

a ruger #1 is a pretty strong rifle

The Shilo Sharps is capable of any load the Ruger is. My 45-110 Long Range Express has digested 500 gn jacketed loads at a chronographed 2200 fps. Case capacity and pressure virtually identicle to 458 Lott, cases popped out like a 15,000 PSI black powder load.

The owner of the outfit Kirk Bryan I beleive his name is, will tell you and has told others his sharps will take a ruger#1 45-70 load. http://www.shilohrifle.com/forums/viewtopic.php?t=2726

I still dont put em in mine, mostly because a 535 graine bullets or heavier are all I can tolerate with no sissy pad shooting prone.

I've always stuck with the trapdoor loads in my Pedersoli because I was unsure of the strength of the action, modern or not. Interesting to see the Shiloh being stronger than I thought

There is speculation that the italians use a different steel for their sharps then Shiloh. The shilohs are 4140 and no one realy knows what the italian ones are made of but some are thinking 8620.

How does 8620 compare to 4140?

 

[hickstick_10]

Depends on the heat treatment.

youl get 57000 psi yield when annealed accourding to this source http://www.onlinemetals.com/alloycat.cfm?alloy=8620
4140 oil quenched and tempered you could get 212000 psi and annealed youl get 60000 psi, but I dont think Shiloh is going to tell us how they handle their receivers as far as a heat treat goes.

Check web site www.bpcr.net in the technical articles section for information on pressures and steels.

According to Kirk at Shiloh they will, but it sure won't be very much fun

Shiloh sharps has not had any of their rifles pressure tested or certified, yet they claim capable of withstanding ruger #1 pressures.
Pedersoli pressure tests their 1874 Sharps rifles to 37,700 PSI/CUP, but limits their certification to 29,000 PSI/CUP. Your choice as to what you do with that.
