Thread: CBTO new projectile

The Sinclair tool is more or lees the same as the Hornady tool, but is not calibre specific.

I'm just being lazy cause the gun cabinet is buried behind piles of crap at the moment and I didn't want to repeat the measurements.

Glad you made that point, different projo's are just that, different. To assume they be the same is not in the shooters best interest. Good luck with your tidy up, let us know what the difference was between the bullets.
I load ELDM's and Siera's (both 155 grain) they go to different specs on the comparator.
