I have a Remington 7600 35 whelan it ejects my reloads with no problem but needs a good forward slam to chamber them, not so quiet in the bush. I was thinking of taking a RCBS small base sizing die that I have and never use in 30-06 and cutting the top off below the neck shoulder portion. My Idea would be to size and deprime cases as normal, then run them through my modified small base die to size them back to the unfired spec. I have noticed that loads with virgin brass chamber a little easier and quieter than my reloads with standard sizing die....So what do you think ?? anybody think of a reason why I should not try this.
Resizing for a 7600 Idea??

When you full length resize, did you adjust the die to make firm contact with the shell holder? If not I would try that first. It seems to me your problem is that the shoulder has not been bumped back sufficiently. If your shell holder does make firm contact, then I would experiment by thinning down the height of the shell holder (the cheapest and easiest component to replace) to set back the shoulder slightly more. When you reach the point where the cartridge chambers easily, stop.
Your 7600 does not have the same camming force that a bolt action rifle has when chambering a round. Your problem may originate at the base of the case, particularly if you can observe any out of roundness in that area of fired brass. A small base sizing die
might be your solution.

That is a good fix as well. Sometimes folks get .30/06 ammo from me then find that the shoulder is too long for their rifle even though it cycled through our two just fine. Running the loaded rounds through my Redding .308 body die, yes I said .308, allows me to set the shoulder back just enough to chamber in their rifles. It seems to me that there is a local 760 that is a bit of a problem child that way.
Has this brass been fired in another rifle? I've often had this problem with once fired brass from another chamber that may be a bit larger.
I have owned several 760/7600s over the years and never had to use SB dies. New brass has always fixed this for me, but I have used Boomer's suggestion with the thinner shell holder with very good results as well.
And BTW .... it's spelled "WHELEN".

I have been reloading since 1978, loaded for almost every caliber out there and have owned and loaded for well over two hundred rifles and fully understand all aspects of reloading. But the 7600 is a platform that is new to me, without the camming action like a bolt gun, I would just like to be able to close the action a little smoother and quieter.Has this brass been fired in another rifle?

I have two 35 Whelens, The brass was new, only fired in the one rifle. full lenth sized. New brass chambers noticably easier than after its been used even once. Thats why I was considering cutting off a SB 30-06 die [I have no use for it anyway] To the best of my knowledge nobody makes a SB 35 Whelen die anyway. I will try thining out a shell holder, but I don't think thats the issue.
Thanks for the input so far.
Bunny,
you do have to shuck a pump gun. FWIW, I have played around with neck size only (accuracy play time) with mine and they still chamber although sometimes need a little extra strong shuck.
With all due respect, I do not know if shucking can be quiete.

Well I did it, cut of my SB 30-06 die I have had for 20 plus years and never realy used. I cut it at the top of the threads and polished it. When I run a loaded Whelen round into the die scewed tight to the shell holder the neck and shoulder stick up through the top. Now I could use this die to small base any cartridge based on 30-06 or 308 even if loaded, although I have never owned a rifle that needed this untill the 7600. The results are that my 7600 35 Whelen now chambers and closes slightly smoother and quieter, the only resistance is extractor snapping over the case head.
I'm sorry, but I wasn't questioning your level of experience. You have been loading longer than me. I was merely trying to share my experiences with the particular style rifle you asked about.
FTR ... I have loaded 760/7600s chambered in 35Whelen (4), 30/06 (4), 308 (3), 270 (2), 35Rem (1), 358Win (1), and 223 (1).

Like SC I also have loaded for a number pumps (and semis) in 35 Whelen and have never needed small base dies either.
That said, not all FL sizing dies are created equal - tolerances at base included - nor are chambers cut the same.
According to machinist and barrel maker Mike Bellm (worked with PO Ackley) the Lyman FL sizing dies are kept to the smallest base diameters. For a similar resizing of the base diameter in particular of his 358Bellm wildcat for Contenders he recommends a 358Win or 444Marlin die specifically but importantly in the Lyman flavour. The other makes just don't do the job he claims. In future sometime I might check out a Lyman 444 FL sizing die myself to see if the 35 Whelen case will go up thru it's body for just such an operation.
Bunny I like your work around. It is far better than messing with a shell holder which could potentailly move the shoulder back which you don't want probably.

It was a RCBS SB die, I cut it with a dremel and cut of disc then polished off the burs with a small drum sander attachment.
All in all Iam happy with outcome, Iam a big fan of 35cal. I have two Whelens, Two .358's and have just aquired a new Marlin in 35 Rem. that I will shoot for the first time tommorrow with some Federal factory loads. I can't wait to get some fired brass back to my loading room and try some 205 gas check hardcast or maybee some 220 speers.
Good luck. A great way to start 2010 - with a new rifle to try. Hope you have some H4895 around for that 35Rem. Many 35Rems respond well to that propellent.
Interestingly I just neck size mostly for my 35Rem lever guns. Sounds odd but works 4 me. I use Hornady's universal 35cal neck sizing die. With all those 35s you own you should maybe get one too. It's quite inexpensive and works well. Others use the Lee neck die.
Don't want to be a downer but the last 35Rem Federal factory ammo I fired was very brittle and no good. I'd watch for neck cracks. Hope your mileage differs. I prefer Remington brass myself.
Been getting my 35Rem brass as needed in bags of 50 at the The Shooter's Den - Sudbury, ON. -phone 1-705-522-2772.
Got my Hornady universal "35 Caliber Neck Die 044046" from Ellwood Epps in Orillia. Paid under $20 for it at the time - but that was a long time ago. Use it as required for all my 35 neck sizing including my AI versions. Only my 350WSM wildcat is too fat for it. Any Hornady supplier should have it available or get it 4u - http://www.hornady.com/store/35-Cal-Neck-Size-Die-.358-1-Each/

When I use mixed once fired .30-06 fired in other guns and FL sized, some chamber easily in my 760 and others need a ham fist. Once fired from my 760 chamber like factory ammo after being FL sized. A few of the mixed cases needed a little extra effort to extract even with lighter loads. Try FL sizing your brass again and see if it goes away without needing the body die.
