Wanted: Larry Willis body sizing collet die
- Thread starter angusb1
- Start date
I’ve spoken with head office and we are hoping to have one available soon, but that is likely to be a good few months I’m afraid. They are still in the prototype stage at the moment, albeit round 2.

An easy much more cost effective alternative is cutting off the neck/shoulder part of a normal FL die and trimming a bit off the base if necessary to make a small base body die.

I actually planned to do this and bought a Lee 3 die set in order to have the neck sizing collet die, and use the FL sizing die to cut down. The FL sizing die is shaving a bit off the brass as I size it but I guess I could lap the edge where it is shaving brass a bit to smooth it. Was wondering about the Derraco solution as it's been 3 months now and I still haven't got round to it. Night work is truly the thief of time...
Really sorry bud, but as far as I know there still isn’t a production model. I know the boss was doing some testing in Oz but that’s where it’s up to I think. Sorry. As soon as I hear anything else I’ll post it straight away! I know as few others are keen to get one as well, so I’ll do what I can to get a couple as soon as they’re produced

But if that theory proves to be wrong this will ruin a £50 die-set.

Angus, save your money as I think you don't need it. I've been using the same 7mm RM since 1990.
This is a Tikka, so has a tight chamber. PPU is always the acid test on Tikka(s), as some new cases need to be resized.
I've always used the Lee CNSZ die to headspace fired cases on the shoulder not the belt.
The occasional case binds & shaves brass, but works fine after it's full-length resized in a standard FLR die.
No-one knows everything, but I try to give an opinion on what I've learned from experience rather than books.

Ah, but it's not a theory - just simple case body sizing. It doesn't require a complete die set - only a used FL die.

Talk sense, man. A 'used FLR die' is all you have to work with. If you mangle the FLR die within a set you've ruined the whole 2-die set. No-one will buy it, certainly I wouldn't. You can always tell when some half-assed mechanic has ground off the relief on the die-base as it's flat. More importantly, you've then altered the critical headspacing as the F1 & F2 dimensions inside are reduced by the amount of metal removed. Advising anyone to tamper with factory-made dies isn't wise.
The CNSZ die is made up of a collet within a sliding sleeve. The recess for the belt is cut into the base of the outer sleeve. It's this recess that binds on the leading edge of the case belt which has expanded, so the collet won't close on the mandrel. Resizing the belt in a standard (unfrigged) FLR die sorts out the problem. It also deals with any bulge that exists, imaginary or real.
My motto is to leave standard FLR dies well alone.
As for CNSZ dies, these set 'shoulder bump' automatically, so no need to worry about it at least for a while.
Generally I don't take advice from tradesmen, salesmen, or gunsmiths who are trying to sell goods or services. The exordium on the LW site is here to read. Although it's plausible enough I just don't believe it, sorry.
Innovative Technologies - Reloading Equipment
Our patented resizing die can reload Winchester, Remington and Weatherby belted magnums up to 20 times, instead of just 2 or 3 times and the top of the die is a chamber width gauge.

Ole discussion but always actual untill mag calibers will be on the ground. So just for adding my two cents cause soon or later any mag rifle will develop the nasty bulge on the web brass depending from chambers measure, brass maker and charge used. Being the Larry Willis as a heen tooth to find in europe I use two systems for saving some more shots from a 3 or 4 time used brass. Easiest but tricky is bonding 2 or 3 layers of 1cm large greased tissue paper (like the one once found in mail's envelopes) around the bulge and pass the shell in the FL die. The bulge will be compressed under the 13mm saami specs. The other is modding a 45/70 FC Lee die enlarging the crimping area some thou and opening the lateral cuts as to have more crimping effect. Need a strong press (as Lee Classic Cast)to manage the pressure needed but is ac av steady and repeatable system cause the mag ring will set the shell from sliding inside the die's mouth exactly on the crimping area. a fat shim must be placed between shell holder and fie's base to protect the collet
