I missed this comment earlier.I have a pinnacle so I'm trying to see based on recoil if I can run it on a 6.8 or 6.5. I have a 300 blackout that I'm a little worried about trying the PV-14 on. I run cans on all my guns as it increases my multiple kills by about 60%. I'm think this may reduce recoil enough to have no worries at all with either the 6.8 or 6.5.
It's not only overall recoil, but the initial recoil impulse that can damage your PVS. I damaged an ITT filmed tube by shooting it on a 9mm integrally suppressed AR. The overall recoil is much less than even a standard 223 AR, but the initial recoil impulse was enough to cause the film and tube to touch causing black spots on the tube. Keep in mind it only took 2 times pulling the trigger to do the damage.
Turns out this initial recoil impulse is largely dependent on the diameter of the projectile, not the amount of powder behind it. So the lowly 9mm was a no go but 223 was no problem....
