I was running a 155 scenar with varget 46.5 grains to be exact. This load was safe in my rifle. I tried it suppressed and noticed shiny spots/ swipes on the case head? The other factor was a new can of Varget. Thanks
Lots of guessing in this thread.
Without doubt a suppressor can add to time under the curve and show swipes and brass flow with loads that don't unsuppressed.
