35 Rem to 356 Win.

[jfisk]

Can a Marlin 336 in 35 Rem be rechambered to 356 Win. I have heard it both ways from different smiths. Thanks in advance.

In theory, yes. The 356, however, is a larger case and will require working the bolt face and extractor. I'm not sure if the magazine will take the rounds. The bolt and magazine are the 30/30 style. It might be cheaper in the long run to replace the barrel with a 35 Remington and then rechamber that barrel than rechamber a 35 Remington gun. Never did this or heard of it getting done.

35 Rem to .356

I think you would find it easier to rechamber for the .358 Win. If I remember right the .356 has a rim and the 35 Rem is rimless (maybe semirimed). The .358 is a necked up .308 and may be easier to fit to the boltface,also brass will not be a problem in the future. Both the .356 and the .358 run at higher pressures than the .35. I'm not sure if the Marlin can handle it. You may be better off rechambering a Rem. pump or a BLR from .308 to .358. Browning also chambered the BLR in .358 in the past so there are used ones around. BTW the .358 and the.356 are almost the same, other than the rim.

I think I'd be worried about possible differences in operating pressure, especially if its an older .35 Remington.

I THINK that the .356 operates at higher pressure than the .35 Rem.

The .356 does operate at a higher pressure than the .35 rem. and the .358 Win. is a bit higher than the .356. I believe Marlin heat treats the metal in the .356 caliber version differently than the .35 Rem. Somehow, it's no a coversion I'd be comfortable with.
