The Lee Collet die is not a crimping die, it is a neck resizing die.
The Lee Rifle Factory Crimp die is to provide consistent ignition in rifle cartridges.
The Lee Handgun Crimp die is designed to keep the bullets from moving forward in a revolver and to ensure reliable functioning in pistols. (Revolvers are NOT pistols)
Instructions that come with them are about idiot proof. No torque wrench needed.
The only place to ever use a wrench on a Lee die set is to tighten the decapping rod collet nut.
This gizmo being sold by
http://precisionaccuracycompany.com/index.html is for crimping not neck sizing. I quote their Utube video:"the consistant crimp is ONLY used during the CRIMPING operation."
For "hunting accuracy" (1.5 MOA) the plain old RGB dies work fine and allow you to follow the KISS method. Having tried the Lee collet and factory crimp dies in "ordinary rifles" like 99s, M -70s, 7XXs, Savage bolts etc., they produce no better performance than any quality 2 die set (including RGBs).
For long range paper punching or varmints, dies like the Redding/RCBS collets or Wilson do make a difference on the assumption that you rifle (and shooter) is capable of shooting bugholes. IMO if you can afford a 1/2 MOA rifle and the scope to go with it, you can afford a $1000 reloading outfit, because unlike the rifle barrel, brass, bullets, powder, primers, it should outlast you.
Reloaders who are anal enough to worry about crimp pressure you should be spending thousands with Sinclair to buy Buggati Veron quality loading equipment not using F-150 level Lee stuff. In a bughole rifle I have never heard of crimping at all. The level of case prep done insures that every case is a virtual clone, therefore bullet pull is always the same.
Wilson does even make any crimping dies.
