I have read of different max pressures for the .357 round and the Marlin 1894C (.357) Carbine in different reloading books and from experts. The variety of comments and opinions have left me with two key questions:
(1) Is the Marlin 1894C designed for more (Paco et al) than the ind. std. of 35 kpsi? The owner's manual is silent on this critical point.
(2) Why do reload manuals listing max loads in CUP generally show a higher max powder load than those in psi (i.e. Hodgdon 158gr H110 is 16.7 gr vs. 15.5 gr. from Speers?
References:
Speers Manual #14: Normal industry pressure for 357 rifles: 35,000 psi
Paco (a): Marlin...rifles will easily take 40 to 42,000 psi
Alliant Power (pistol loads 357): 33,600 psi
Hodgdon Manual 2008 (pistol loads 357): 43,200 CUP
Lyman Casting 3rd Ed (pistol loads 357): 42,000 CUP
