Think I just proof tested

[charger 1]

50 grains of IMR 3031 behind the 500 gr lee GC in the farmingdale shiloh 45/70 (by accident) Not rough to extract but a swollen primer. No ring in barrel. I think if that would have been copper clad I'd be pooched. Me thinks me lucky boy. They were quenched to 23B too

I shoot 50 grains of 3031 behind a Rem 405gr jacketed soft nose in a Marlin 45-70. You are right about it being a stout load, I imagine it'd rattle the cage with a 500gr boolit!!!!

Ya, I think Marlins are proofed higher than first prod shilohs. And yep I'm a recoil junky but I got a bit of a skull cramp after that round. Glad my baby ain't in peices. 40 grains is a nice gentle 1390 fps you can live with

I fired 50 grn 3031 with a 500 grn Win Softpoint in a Siamese Mauser. The pressure was higher than other 45-70 ammo but not especially high compared to a smokeless round.
The brass that I used has been fired many more times in several other rifles so it was not damaged by the pressure. Due to the recoil I would not recommend that load and it should not be used in any older rifle or designs due to the unknown but much higher pressure.

If i let Quickload do it's mojo and stick to standard seating deapth then the filling is 130%!
It seats the boolit .864" for a total of 2.55". Pressure @ 5160bar~74800psi wich is just a tad over max. ;)

Since this cant be done i suspect that you are more in the visinity of (i grabbed an arbitrary number for seating deapth .591") 104% filling and 2680bar~38900psi.

The CIP max. is 2200bar~33660psi and i know that at least Pedersoli tests to 30% above max. (2860bar~43760psi) so you're in the safe. But dont make it a habit:-D

Pardon my french, but NO ****ING KIDDING I have an old couch I sit @ the end of, open the patio door and let sliver. That load rolled me over the couch like a bowling ball. Ya no repeats. I promise. Pinky swear

No offense but your Quick Load is not worth a dime for predicting pressure with that combination.
The Winchester bullets are a two diamter design. The shank was .457 behind the cannelure and the nose ahead of the cannelure was .448.
The original data my load was based on came from a Handloader Magazine (late 60s) that I believe has 55 grains of 3031 listed with a 500 grain bullet as a max load in bolt guns. I had no interest in breaking the stock on my rifle so I only used the 50 grain load. There was no compression of the powder. Recoil with 50 grains was substantial but the brass and my rifle action was not strained at all.

You believe? You don't know?

And upon what do you base your statement that Quickload is not worth a dime on that combination? Did you design Quickload?

And exactly what makes your Winchester bullet interesting regarding my calcs of a Lee 500 gr CG boolit???
