I have a ruger security six and a marlin lever action both in 357 cal. I have been pushing a pced Lyman 358 165 with gas check using 2400 powder and getting 1260 fps from a 2 in barrel. Will this be too much for the marlin or can the marlin withstand a higher load than the ruger. I am hoping to find a near max load for multiple use in both guns.
