I've run both mine and Em's with the suppressor... and accuracy doesn't change, but POI changes about 4" (straight down). I'm at about 200 rounds through mine since it was last cleaned... it shows little/no effect
Dog shooter,
Straight down is good… much easier to compensate for if you don't have to correct for windage.
What does your suppressor weigh?
Tikka CTR's; They are coming out with a stainless version, a whopping $150 up charge. Don't think they have them in stock yet.
