[QUOTE="okietom, post: 2386752, member: 18710"] I found this on another forum. Tom From: "John Lee" <info@leeprecision.com> Subject: Re: Factory Crimp Die for lead semi-auto calibers To: "XXX" <XXX@yahoo.com> Date: Thursday, October 13, 2011, 11:26 AM Thanks for the suggestion of a Factory Crimp die with an interchangeable sizing ring. I will think about your suggestion but have serious reservations about producing it and calling it a Factory Crimp die. If we make the sizing ring any larger it will not produce ammunition that will work in any firearm. I guess we could advertise it as "Produces ammunition that may work in some firearms" Seriously, the sizer ring is .001 to .002 smaller than a SAAMI maximum cartridge. This produces a finished cartridge that will not exceed Factory Maximum, a dimension necessary to fit in any standard chamber gun. Many users can use larger cast bullets that swell the case in excess of factory maximum and will work perfectly in one or more of their guns. That same crowd frequently will use a taper crimp die to assure "reliable feeding". The taper crimp die nicely squeezes the brass in turn reducing the bullet shank diameter. Had they used the correct diameter bullet they would not have needed a taper crimp die nor a Factory Crimp die. For any given brass thickness there is a limit on how large your bullet can be and not swell the brass over the SAAMI limit. If you are using selected brass of uniform wall thickness one can successfully use larger cast bullets without fear of producing ammo that will not chamber properly in any gun. If you are using mixed range brass stick with the bullet diameter that the cartridge was originally designed for and you won't need a taper crimp die nor a Factory Crimp die. Again thank you for the suggestion for a "screw adjustable crimping die" basically our Factory crimp die without the sizing ring, it would be a fraction of the cost of Factory Crimp die without the ground and polished carbide ring. Bounce the idea off your friends on the forums and if there is much interest I will give it serious consideration. Sincerely, John Lee, President [/QUOTE]
