Short answer, pick a different rifle to suppress. I've told friends that want to get into suppressors that it WILL change the way they look at firearms in their existing inventory as well as future purchases in terms of, CAN I SUPPRESS IT? Once you have suppressors you don't go back to shooting unsuppressed, just saying.
I have a Ruger American Predator .243 and I can assure you that while the POI changes with the suppressor, it still shoots sub MOA with my handloads all day long so whoever wrote what you read about it not being accurate must've just finished hitting the bong. Since my State has made hunting with suppressors legal, the POI change from suppressed to unauppressed is a moot point. As the old saying goes, SUPPRESS ALL THINGS!
