A 475 linebaugh would work well. But I think a 460s&w might be good.
Both of those are well beyond the pressure limit of a SMLE action, Especially the 460.
Plus I've got an old shot out martini Enfield anyway.
The number of ideas I would like to build on a ME but I never find a donor.
Is the ME much stronger?
I am by no means knowledgeable about the SMLE.
Is the No4 any stronger?
I was basing pressure ratings on CIP data, in my opinion the Americans and SAAMI, tend to down rate pressure ratings of most European and Russian rifles/cartridges! I can't think of any reason they might frequently do that
According to American sources the M96 is garbage and is barley fit for the 6.5x55 and could never take a 308, the K98 is okay but so weak compared with their M1903 and the Mosin is just Russian garbage! (on a side note I read about a rifle destruction test where a load with a full case of Unique was used in a 30-06 M1903 and the same in a M91/30, the M1903 failed catastrophically, the author predict even worse failure for the M91/30, it was pretty sick after, but didn't actually fail catastrophically.
Anyway back to the case in point, CIP rate the 303 at 53,000 psi (I assumed that as by the far the most common rifle would be a SMLE, that they based it on that
)
475 Linebaugh at 50,000 psi
460 S&W at 57,000 psi so a define
there!
However the Mosin according to CIP can take 56,000 psi and therefore could theoretically handle the 500 S&W at 54,000 psi.
As I said, I can't speak of the SMLE, but I trust CIP and the Europeans over the SAAMI setup.
