Rechambering question

[doetag]

I am wanting to rechamber a Rem 760 in 35 rem. to 358  win.. I called a local gunsmith and he said the remington pump could not be rechambered because of the locking lugs inside the barrel itself.But i thought I had read where someone had done this. Is this possible? :?    Thanks for any help!

You are quite correct.  The 35Rem to 358 is an easy rechamber.  It does require a competant smith but any rechamber should.  The 358 reamer will remove all traces of the 35 rem chamber.  The smith must have misunderstood and thought you were contemplating a re-barrel.  That too is possible with the 760 but most smiths won't attempt it.  The locking lugs of the 760 are not in the barrel itself but in a barrel extension which is screwed to the end of the barrel proper.  It is not an easy process to remove this extension and I admit to having never attepted it.  On the other hand it is do able.  A simple rechamber such as you are suggesting is quite easy...  simply remove the from the receiver and with a proper reamer deepen the chamber.  The bolt head and a headspace guage will let us know when we have arrived at a 358 chamber.  One could do this on a lathe but is simple enough to be done by hand..

Hey who put all these trees in my forest.  35 Rem to 358 Winchester of course.

I have an XP-100 in 35 Rem and I always wanted something a little more energetic....

Thanks for the idea!

Gander Mt lists this conversion on their Gunsmith Services for around $150. I had one done (not at Gander Mt) and loved it. Great Pennsylvania Deer/Bear setup...Good Luck

Thanks for the input guys , I really appreciate it. I seen the add at gander mt., sounds great ,I would have thought it would cost more to have that type work done. Ive been wanting a 358 for a good while, but not a big fan of the BLR , Always liked the pumps  and bolt guns

Does anyone know if this is also a doable conversion with a Marlin lever gun? I know that the Winchester (except the BB 94) is not strong enough. A lot of people are saying the Marlin in 30/30 will convert to 307 so this has me wondering. I think this is a better conversion.  Best of luck. POW

The 35 rem to 358 would be easy but even easier would be to simply order a 356 barrel and install it.  Then one could swap back as you wished.  The 356 was a rimmed round so the barrel designation would have to be altered.  There is a concern though.  Evidently 358 ammo is loaded to higher pressures than 356.  Although there is little difference in cartridges there is a difference in how they are loaded.  I will attempt to find more info and get back...

I was assuming that the 358 Win is an easier round to locate and more likely to be with us awhile. Best of luck. POW

In that you are most probably correct.  The 358 never really caught on but can't seem to die either.  Too many diehard 35 caliber fans...  and it's the short action round of choice in 35 caliber.  Another rechamber I've been researching, and havent reached any conclusions about as of yet is from 35 Remington in the Marlin to 358.  We know this will work in the 760 but will the 336 handle the increased pressure of the 358.  It handles the pressures generated by the 356, the rimmed version of the 358, but supposedly the 358 is loaded to higher prssures.  I had always just assumed the reason the 358 wasn't the original caliber Marlin went with was because of the pointed bullets normally loaded in the 358 and the possibility of a detonation in their tube magazine..  The 358 would surely generate enough recoil to make this a possibility..  Perhaps a spiraled magazine as in the M14-141 Remington would ease some fears??
