Belted magnum collet die?

[manitou]

I have a new one (Innovative Technologies, L.W.collet die) that I won't use if anybody is interested. Sold my 7mm Rem mag. I would let it go for 75.00 shipped

never needed the collet die on my 300 win mag. I use the forster die set that has to be 12 years old fired case .514 above belt sized case .5125 with a .002 shoulder bump. never needed it with my 264 win mag either that used RCBS dies.

If you only use brass from one rifle in that same rifle, you'll probably never need this die.

However, if you ever buy used brass or swap between rifles it's a very handy tool to own. You only have to get one case to stick before you really like the ability to resize just above the belt and have them fit.

Anyone that would be mad at somebody that would buy this die doesn't understand its purpose in my opinion. If you 100% FL size a case every time you probably wouldn't need this die. I always FL size new brass to ensure uniformity to start with. In my 300 WinMag with a SAAMI chamber starting from virgin brass, after a single firing my headspace grew .021 inch. That means if I wanted to full length size to ensure the ENTIRE case body got sized (including just above the belt) I would be bumping my shoulder back .021". That's way too much in my opinion, and even with annealing I don't think I would have gotten very many firings on a piece of brass. The Larry Willis die allowed me to size the case body just above the belt and then in a separate operation control my headspace with a .002-.003 headspace "bump".

Your statement here is completely false. No FL die is going to bump your shoulder back .021". PERIOD.
Belted magnums headspace on the belt, brass manufacturers keep this dimension pretty tight in most instances .220" +/- .010", BUT, when it comes to shoulder position they are slack in this area as it is not critical to keep it tight. The reason a belted case doesn't separate on the first firing is due to the belt, not the distance to the shoulder.
The die has the same dimensions as the chamber minus .002"-.007", so your die can ONLY size your SHOULDER TO HEAD dimension by a maximum of .002" beyond SAAMI MINIMUM.
BTW, the headspace dimension on a belted cartridge CANNOT be changed by sizing the brass, the belt datum does not change during firing or sizing, you are only imparting CLEARANCE from HEAD TO SHOULDER by bumping/sizing the shoulder.

I have never had bulged cases, as Larry Willis class it, in over a dozen belted magnum rifles I load for.
I know it exists, but loading technique, chamber design and brass choice can ALL contribute to the problem.
Just to let you know, Weatherby/Norma brass appears to make the problem worse as it has thin webs.

Cheers.

I picked up a LW collet die a few years ago when nearly all calibers of brass were hard to find. i picked up a couple of hundred pieces of once fired WW 300WM brass. Even after FL resizing the cases, they would not chamber in my rifle. After running them through the collet die, they chambered perfectly. I don't seem to need it when I buy new brass for my belted rifles but now that I have the die, I'm not afraid of buying once fired brass if I have to again in the future.

Will this die work on a 338-378 Weatherby ? I have been having trouble chambering rounds after fl resizing thinking that I was not pushing the shoulder back enough.So I started using the Redding competition shellholders in stages untill I could feel easy chambering. I still had chambering issues with stiff bolt closure so yesterday I smoked some brass that was fl resized and sure enough the area just above the belt was wiped off. I own 2, 257 Weatherby's and previously a 340 and had this issue with 1 of the others only.

It will not work on Weatherby's 378 based cases. Too large. It would work on the 257-270-7mm-300--340 . All belted cases this size.
