Yes.
If you are worried about the "Bumper" on your JP SCS wearing out, you can pull it out and check it every 500 or 1000 rounds and see if it shows any wear. If it does, you can get a new one in the JP "SCS Maintenance Kit".
I have original "version 1" SCS's from over 15 years ago with...
The way to say that would be: Device B has 2.43x the amount of recoil energy vs. Device A.
But bottom line, yes, the RR brake does have a dramatic effect on recoil energy compared to the same suppressor without.
Also note that that particular graph is data from 300WM. Data from 308 is a...
That's not now "reduction" works.
If a bare muzzle has an amount of recoil energy that is normalized to 100 units, then:
Device A has a 65% reduction, so it has 35 units of recoil energy.
Device B has a 15% reduction, so it has 85 units of recoil energy.
I think you are trying to calculate...
Yes, you are reading it wrong.
ETA-- you are dividing 65 vs 15 and turning into a percent and calling that reduction. That's not how any of that math works. What you are reading as "65" and "15" are the percent reductions in recoil energy from a bare muzzle (per the legend on the left)...
A lot. In this graph the RR models have the brake on the end.
ETA: Also, the Ultra50 recoil reduction compared to a bare muzzle on 50BMG is 65% reduction.
No, that is incorrect. The RR brake comes off.
The RR technical manual shows how to remove it. We have videos online showing it being removed, re-installed, and how to clean the tapered interface between it and the can.
