Hello @cp255,
I recently bought a TL3 Proof Prefit for my TL3 Just a plain standard Dasher Comp contour 7.5 twist rate.
I handload alpha ocd brass with @BartsBullets Gungnirs in front of 30.50 grains of VV N150, CCI 450
here is one of the last range sessions 100 meters, 200 rounds down the pipe. 10 rounds, garmin xero output enclosed. The flier is on me was the tenth shot and my hands became a little sweaty ( or was me drooling over them I don’t know)
I’m on the left side of the Pond other than that I don’t see any reason you not being happy with that.
I can pm you the US retailer where mine came from, if you wish.

I reached out the Proof Research. They said...
Our Dasher chamber is designed to work best with the Alpha and fire-formed Lapua brass and with 105-115 gr bullets. It has a .125" long freedbore and a .274” dia, neck. The maximum overall length that I recommend for our chamber is 1.550”; trim length would be .010” less at 1.540
