Hi,

I'm curious if anyone out there has ever rechambered/converted a Remington model 7600 pump to .358 Win. ? If so, can you give some details and let me know if it was a success?
Thanks.

I have seen some of the BLR 308W chambering barrels bored out to 358W and this seems to work very well.
If you can find a smith to rebore your 308W bore, every thing else should fall into place -as the 308 is the parent
:cool: Should make for an awsome Bear /moose / deer Gun.
Hope Remington offers this chambering someday in the 7400/7600 as well as the 35 Whalen. It would be a great eastern rifle to those that have read up on the virtues of the 358W and heavy bullets.

It's true the big thing will be getting the barrel and chamber rebored to admit the larger bullet. Even the magazines are interchangeable, or at least they are in some model rifles.

I once had a pre 64 Winchester 88 in .358 Win. Attracted to it because of the smashing great heavy bullet stepping along at a good clip but other than the slick action I was disappointed in the results. That smooth lever with the rotating bolt lock-up was a real turn on!

I was using RCBS dies, Speer 200, 225, and 250 Gr jacketed bullets. I tried whichever IMR was popular at the time, as well as one of the H-3XX series, pro'ly 335 but this was happening in the late '70s and I do not remember now. After creeping up and down the scale with powder charges the accuracy was never any better than mediocre, and every once in awhile a bullet would hit sideways at 100 yards.

On the other hand, the fellow who bought the rifle was so tickled to get it I have sometimes wondered if I was going at it wrong.

Well it might have been just a powder change.
the imr 2015br is noted to work good in the 358W.as well as Winchester powder .
I just got my BLR in 358W this year and had some H4198 powder that I was using in the 45/70.
Well loading a box of 220 speer using ths powder and federal match primers, I was every pleased with the results with a inch group @100 yards.

Heard that remington built a limited production 35Rem pump this year . You might want to check if this rifle could be converted to 358. you might be able to get away with reaming out the barrel for the 358 case and changing the bolt.
I am not sure if the rifling is the same.
Now a 7600 in 35 Rem. should makea good bush gun too.

Wish you well on your project.

I've seen a couple, I know that Gander Mountain offers the 35 Rem to 358 or 35 Whelen. Of course Remington has produced 35 Whelen 7600s again this year. My local dealer has/had (haven't been there in a month) one. If you want the 358 the 35 Rem conversion is cheaper than a 308 rebore. If you just want a more powerful 35 and the Whelen looks good to you try to find one of the New Remingtons. Any Rem dealer should be able to get one. Sean


P.S. You may need to use 308 magazines instead of the 35 Rem mag but that isn't a big deal. Sean

I wonder if the short action has any faster lock up?
The Whelen is a step up from the 358W and that is where I would go.Save your money.

Well... I took the plunge and picked up a M7600 carbine in .35 Rem yesterday. Looked at the 35 Whelen for a while until I decided that the .358 Win is the way I want to go.
Now I just need to find a competent Smith to do the work.
Any suggestions?
I live in Northern Vermont.

Dave, I converted a 760 35 Remington to 358 Winchester. My gunsmith said it was "simple" job that only involved rechambering. The 35 Remington clip was replaced with a newer model 243/308 clip that required slight modification (the "ears" had to be lowered). The gun shot well, as without extensive tuning, I got 1.5 inch groups at a 100 yards using (if I recall) 225 grain bullets. I was initially concerned about the difference in twist between a 35 Remington (1:16) versus 358 (1:12). My research and chat room discussions concluded that the slower twist for the 35 Remington should not make a difference unless long spitzers such as 275+ grain bullets were used. That problem became moot as the COL in that gun was limiting for the long spitzers.

Good luck!

I met a gunsmith at a show last year who specializes in the 760, 7600 rems. He is located in North Hero VT, phone 802 372-8812. This conv. 35rem to 358 was popular. Are you sure you want to alter that carbine it will have some collector value, I think they only made 500. I bought the same rifle saturday, mine is staying put as I have a BLR81 in 358. Good luck
