When reloading for two different rifles that are the same caliber do you have two different dies for each rifle? I’m thinking that it would be easier to just use the appropriate die to the rifle so that no adjustments would be required.

No I move the die as needed. Tick Mark's with Sharpie on the threads is handy.

I always used one but two sets does have advantages

Or you could try the Whidden click die which allows you to go up or down in .001 clicks up to about .015 total.
Or just pick up this which does the same.

I have two very accurate.223 bolt guns that I have a separate set of dies for each. I shoot them a lot. The price of a set of dies was well worth the convenience. Particularly for sizing cases.

I would think it would depend on how far each shoulder needs to be bumped back to achieve .002-.003 bump. If very close, I'd use the same sizer die. For bullet seating there are many micrometer seaters that are quick to adjust.

Depends on what your doing. I have a 270 load that shoots great in both my 270 and my brothers. I FL size everything but still try to keep the brass from mine and his separate. Its not a load I would shoot long range with but it is more than adequate for hunting and at 100 yards is less than MOA in both rifles.

I would use the same full sizing die only if it can bump shoulders back .002" - .003", if not perhaps use shims to adjust shoulder bump or use Redding Competition shellholders without touching adjustments on the die or buy a 2nd die for a different rifle. If my load shoots so stupid accurate, I would not touch my die at all.

I don't have that problem but if I did, the cost of the extra dies wouldn't bother me.

I use die shims. Set the die for the shorter(est) chamber, then use the die shims to get you to the longer one(s.)

+1.

Yeah that's where I'm at. You mis-adjust one time thinking you did it right, and go through 100 cases and you could have paid for the 2nd set of dies.
