Sure is, loaded it for a short while.I load 5.7x28 and the amount that the shoulder moves on each firing is insane.

Only trying to minimize the damage to the brass. Have not done well at minimizing movements by my use of a small base die.
I will disagree with you on this one.
I load 5.7x28 and the amount that the shoulder moves on each firing is insane.
On my first attempt to reload 5.7x28 I tried to push the shoulder back to where it was supposed to be and my die wouldn't do it.
I had to remove 0.002" off the bottom of the die to get it there.
My comparator set didn't have a small enough bushing to accomodate the 5.7x28 cartridge so I used a 26 cal bushing.
Without a comparator there was no simple way to calcualte how far to push the shoulder back.
I also use one for setting up my sizer for my M1A National Match to work the brass the least amount possible
In fact I do use the above in actual practice.
I am banging away with a 308 M1A and have read that brass life is only 3-4 reloads.
M1A - Off-topic a bit, yes ... but look up Larry Gibson's result of using the special RCBS 'X' sizing die for semi-auto rifles, as he got > 16 reloads out of M1A cases without any trimming. He only stopped the testing @ 16 as he figured that was quite good enough ... expanding his useful case life by a 4X factor! I use one for my precision 5.56mm loads and it's excellent!We may have a diverging concept here.... that gun [M1A] is very hard or brass and minimizing brass movements will help, but it's not a one stop shop for lifetime
I have more than one firearm in that caliber.In both of these use cases, you could accomplish the same task - making ammo to fit your chamber, with a sizing die and the rifle.
In reality all you need is a Lee Loader and a piece of wood.
'Fraid not.suggesting that a comparator is necessary to be able to set shoulder bump specifically
to individual rifles and without a comparator, only generic ammunition can be made - is false.
Read my response above. Rear locking actions with excessive case stretch are another example where blind use of a comparator instead of using the actual rifle can lead to improper set up of the die, and then feeding and extraction can be compromised.
Wouldn’t you be taking the actual dimensions when measuring the cases fired from the rifle using the comparator?
Of course one can do it, but I would have to ask the point of reference (actual measurement
value for the record books) when changing from rifle to rifle.
If one does not understand why two (or three) different case headspace dimensions for two (or three)Why do you need to use ammo dimensions for one rifle to set a die for another?
I’ve just never been a bolt stripper, lots of guys are but I’m afraid of small parts getting lost.I stripped the bolt for finding the lands to start. I started at .020 off the lands, and never chased them on that barrel.

different rifles requires the dies to be set differently between loading sessions
I once dated a stripper, does that count ?C’mon, Jim - you gotta strip dat bolt like you’re tryin’ to pay for college!!

Some of us like to have more control/sleep better at night.
I want all of reloads exactly the same as the ones before.
