Went out today to record fresh numbers for some DA cards with my POF 308. Also first time shooting this gun with a new QD YHM Phantom. POI shift with the suppressor was a suprising 0.3 mils up and no shift in windage. I had read these cans were very repeatable but most got a fairly good sized shift. Not the top of the line suppressor by any means and a heavy 28 oz. but for me it is just about right. We can't hunt with suppressors in NC so it is only for practice shooting steel and will be moved from this gun to my .243 and 30/06. Good noise reduction and no flash noted in the dusk. Maybe I got lucky with this suppressor and the POI shift. I took it on and off for 4 five shot groups and it was consistent. It will be interesting to se what it does on my other long range bolt guns. For reference this is a 16" gun shooting 155 Bergers at 2610 fps.
