    35 Remington rimmed

    I've got a 35 rem Contender barrel that I think I would like to have converted to taked a rimmed case. It is my understanding that one could use 30-40 Krag or 303 British brass, formed in a normal 35 rem size die. I think normally that the brass is trimmed back to 35 rem length but I was wondering if I could have the throat opened up to keep the full length of 303 brass. This would make case forming that much easier, get rid of the poor factory throat, and make a nice, long neck for boolits. Anyone else have this done? Who would you recommend to do the work, especially someone on the forum that understands boolits for the throat?

    Couldn't you just take it to .356 Winchester and treat it as a 358 Winchester? In that action, I imagine the brass would be the only weak link....or your wrist. LOL.

    I've reamed a CVA in 35 remington to 358 Win with no issues. You'd get the rim and factory brass.

    I read of it done using 303 brass but both it and Krag cases are hard to come by now.

    Just my $.02, maybe find a number of cases before the transfiguration.

    I have a contender barrel that is chambered for this. It uses 30-40 brass formed to .35 Rem at standard .35 rem length. I have not played with it a lot, but if I can answer any questions let me know.

    I have been meaning to try it with .35 Remington factory loads. I would have to eject them with a dowel but I am curious. They should work.

    The 356 has been done by Don Bowen. I believe it was an AI cartridge tho.Treating it like an 358 win is out of the question. Too much pressure. The 303 brass is available from Hornady and PPU. PLENTY around.

    No sweat- Essentially a 35-303 AI is good for the chamber configuration. It's been done and would perform well.
    When you wildcat the 35 the options are vast. I like the 358 Bellm with a nice long .5" neck for lube grooves in cast. That's the 358 Win size die on 444 marlin.

    If you really feel the need for more case capacity and perhaps a longer throat the full length 35-303 would be my suggestion. Reamers are readily available and the reloading dies aren't as expensive as many wildcats are. However, keeping the 35 Rem chamber would be the simplest option with a throating job and simply chucking the barrel in a lathe and open up the rear of the chamber for a 303 rim. Both should be very easy and done by any competent gunsmith. The 35 Rem R is easily made out of 303 cases with standard 35 Rem dies of which you probably already have. I just formed a 35 Rem R out of a once fired SA 303 case. Was very easy to do and it should fire form with any standard 35 Rem load of which there is already a plethora of data.

    Might want to turn the neck and maybe anneal the neck and shoulder.

    35 Rem R on the left.....standard 35 Rem on the right.
