When working up a new load and running a suppressor, do y’all run the suppressor or no. It’s going to change velocity with or without the can. Wasn’t sure if it’s best to find the node with out it and then run your can and change for poi. Thanks

On my rifles that use a suppressor I work up the load with the suppressor on. The extra weight probably has an effect on barrel harmonics. I'm sure the suppressor has an effect on velocity as well.

Work up the load with how you plan to shoot the rifle. If most of your shooting will be done suppressed, then certainly work up the load with the can on. The suppressor adds about 3K-5K psi to the round. So if you work up a max load with the can off, then add the suppressor, you can easily be over max and have a hot load. Also, there may be a POI shift between can off and can on. It is repeatable and make note of the shift for future reference.
