Group difference suppressed/un-suppressed

[Double Naught Spy]

Yes, a known stellar performing bullet but with a different powder and unsuppressed. Too many variables. Going to back up, shoot with the known well performing load again suppressed to verify there isn't a new issue with scope/mount etc.

I'm going on a Western hunt and would like to shed the weight of the can. Earplugs=less than an ounce, suppressor= 1.5lb.

If you switched out your left front tire and now have a wobble in your steering, do you then go back and check the shocks to make sure they are correct? You can, but that would seem to be what you would check AFTER you determined if the new tire was at fault or not. Or, in your case, have you also messed with the scope/mount etc. as well changing the suppressor and powder?

Any time you add a suppressor to a rifle/load/bullet combo or remove a suppressor from a suppressor/rifle/bullet/load combo where everything was good before the alteration, you may get a change in group sizes. You may get a POI change.

Bottom line, you may have to work up a new load to get the same results with the suppressor off as you had with the suppressor on the rifle.
