I have about 2500 rounds through my savage 10fp in .308, barrel cut to 18" by AWC, and use an AWC thundertrap. I have found the gun is capable .25MOA accuracy at 200 yards, and is nowhere NEAR this accurate w/the can off. I shoot federal gold match .168grn, using my 3rd gen SA BDC reticle and have never had an issue.
My rifle is usually the talk of the range when I bring it out and is scary quiet with sub-sonic. I recommend EBR sub-sonic over TTI, because I have had too many squib rounds using TTI.
You will not regret using any of the following:
• SRT Shadow - the quietest I think going now?
• AAC Cyclone
• AWC Thundertrap
• Gemtech TPR-S
• SoundTech BlackStar
• SWR Omega 30
If more people knew how easy it was to get a silencer, and how beneficial they were more people would have them, IMHO.
