My brother is a smith so I get to try new projects as they come to mind, and a Marlin 336 in 356 win was my lat one that came to fruitation. Next is a Ruger 77 that I have recently aquired (now a 270), being turned into a 35 Whelen.
The 358 and the 356 Winchester rounds are NOT exactly the same, the outside dementions are as you use the same dies and reamer, but, and I MEAN but, the brass for the 356 is much heavier walled to withstand the 52k cup pressures that it is factory loaded to. All the Winchester Big Bores, ie 307, 356 and the 375 share this trait. That is the only reason it is acceptable to shoot in a lever gun designed for 38k to 42k cup. In a pinch, one can shoot 358s in a 356, but I would seriously consider downloading a bit to keep a bolt from giving the shooter a lobotomy. I know there are many that do shoot factory loaded 358s in the same set up that I have, but to be the first casualty is not a record that I want to be famous for.
The gun has not yet been shot over the chrono but will submit the figures as they come in. But the gun has been papered and with all that I have tried thus far, it shoots so well, those bolt guys have to work for bragging rights.
Thanks guys for the replies and hopefully some intrest will be renewed in this overlooked cartridge. Long live the 35s! One only has the use a 35 caliber in the field to see what it has going for it, paper ballistics dont kill deer. Be it a 357 magnum up to 35 Whelen......even the 358 Norma Mag.
