Suppressors 1.2 mil POI shift. typical?

[Winny94]

Was testing out poi shift w/ my tbac 338sr, and was a bit surprised to see the shift is 1.2 mil straight down. Group size was still very nice, so I doubt anything is wrong. Just curious if anyone else has that big of a shift

That's getting into territory where I'd have the threads and mounting of the brake checked. Group size good indicates it's not getting critical. Also, a longer and/or less stiff barrel, or more flex in the action can cause more droop, which is almost always straight down. What's the rifle/barrel set up?

It's a 26" proof sendero (carbon). The brake was timed/installed at LRI when they chambered it.

Pretty typical. Mine is 1mil lower poi shift

Doesn't seem surprising for a 20oz can on the end of a 26" barrel. ~1 mil down is pretty normal, at least for my can/rifle combos.

I changed from one brand of brake to another and got 1 Mil shift straight down so I'm not overly surprised by that amount of shift on a suppressor.

Can’t speak for the Thunderbeast 338, but my Shark 338 can takes my POI down about the same as yours
