Take the sights or scope base completely off if possible. If you're testing for pressure you shouldn't be trying to shoot groups anyway.Hi,
Question (a repeat from my intro in General):
How do you mount a chamber pressure strain gauge over the center of the chamber of a Contender? To try to stay away from the barrel cross section changes of the barrel locking lug, on top of the barrel seems to be the ideal. BUT, over the chamber, on top, is where the sights or sight base for a scope is mounted.
I want to test pressures in .357 Herrett (iron sights), .223 Rem (scope mount), .44 Rem Mag (ribbed barrel with the shot spreader removed) barrels (more IF I can afford them). It is a GEN 1 frame.
Open to ideas/suggestions/blueprints!!!!
