Is it worth getting a Wilson cartridge gauge for .303BR?

[CINDERS]

I lock my calipers trim those that need it, this may seem a PITA to some but I keep all my brass with the same rifle FLS'ing @ every 3rd firing as I only have 4 shooters and 2 safe queens its not that hard.

After tumbling or sonic cleaning which ever I decide on its a case (Pun) of TTL, Chamfer, Neck size, inspect & clean the pocket (Sonic normally cleans this out well) then reload with a light crimp so neck tension is as close as possible the same for each round.
I get good life out of my cases I have had 3 head separations in 22 years (Always in a timed event!) I normally get between 10-12 reloads from a case before after wiring them consider them binable mind you I am using AR 2209 with a load that keeps pressure down to around 38,000+ psi the bullet is not doing 2440fps but the better SMK BC makes up for the reduced velocity V's transonic/subsonic flight at longer ranges, I found AR 2208 a bit to sharp.
