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.
If you are going to shoot a lot of 50 from bolt guns, the only reason to NOT suppress it with an Ultra 50 RR (or another can that has similar overall sound & recoil performance... if any exist??) is for concerns of cost, or weapon overall length. The difference in shootability is dramatic...
I'm not sure, we have shipped a lot of them but they also sell fast. If you need help finding a particular model in stock or "about to be in stock", please email us and we can do some research for you
I don't think we have recorded data on the 6mm's, but Sam reports that with smaller-capacity 6's, the K and S work better, since they don't have enough gas left over in the full lenght one. Talking recoil reduction
