Did some testing on it today w/ the Rem 700. Out to 100 yds it's good & POI is about same as POA - not making any adjustments suppressed vs unsuppressed. But at 300 yds, I'm not on paper on a B27 full size silhouette. w/o the suppressor I can do 2.5" groups easily at 300 yds with this rifle so something is going on. Tried aiming at each of the 4 corners even so something is up there.
On my 16" AR the POI is about an inch high at 50-100 yds, but at 300 it seems to be the same - my 300 yd groups with an Aimpoint aren't really tight, but everything is in the black w/ or w/o the suppressor. With the 22 conversion kit in the AR, it sounds about the same as my other rimfire suppressors so that's good.
Build is nothing fancy. 4140 tube, caps, & spacers, 416 baffles. Diffuser, 3 K's, & 2 60° cones. I think it works well. Sounds like an unsuppressed .22LR -maybe a little quieter. The downrange crack is the noisy part.
I don't think I'm going to play around with working down a sub load. I think .223 subs are kind of pointless to begin with & this rifle has a 1:12 barrel so I don't even know if it could stabilize a varmint weight bullet moving that slow. The ammo I used today is the hottest I have. I figured that would give me the best indication of it's performance. It did seem a little quieter when I switched back to my regular target/plinking loads which are over a full grain less powder.
Gets crazy hot, so I need something to handle it with. No surprise there, but I didn't realize how long it would stay hot afterward. Are the silicone baking mats they sell at WM for about $10 sufficient? The Manta sleeve looks really cool, but $65 for what it is seems like a lot.
