I'm working on a 300 Whisper project. I am thinking about a Gemtec TPS suppressor with the BiLock system.  Has anyone had any problems with "standard" subsonic ammo with this setup?
JD mounts his suppressors further back, but the standard Gemtec goes 9" out from barrel. When I say "Standard" I'm talking 1:8 twist 16" shooting Cor-bon 220gr or reloads pushed up to just below supersonic.

From what I've read the 1:8 doesn't have any problems stabilizing the 220gr. But the disclaimer from Gemtec makes me wonder if there has been problems. Real problems or just some bone head errors.

Call Dr. Dater at [url=http://www.gem-tech.com]Gemtech[/url]. He’s always been more than happy to answer any questions I have had.

Best regards, J
