Now you've gone too big, need the other 300. A 300 BO SBR with subs would be about right and stay well within range of the scope. Then get a tacticool silencer to go with the tacticool NV scope, tacticool caliber, and tacticool stealth black socks.
I am kidding of course. Don't like the 300 BO. Have a couple silencers and an SBR, all of which are fun and have their uses. Dad's got a pair of NV scopes, one looks like what you have there and the other is an ATN. The were purchased for the same purpose, varmints and hogs. I would like to have one myself, but don't have enough opportunities to use it to make the purchase worth while.
Unfortunately my yard is lit enough that I could handle any pest problems with a scope and maybe a flashlight. Only real pests I have are fighting/mating cats, an armadillo, and the occasional dog that likes to pee on my car.
Haven't used any Agulia subs, but I've got some 750 FPS CCI and they are quiet. I want to see how they will perform out of a silencer, but I'm still waiting for my dedicated 22lr can to be approved. I've also shot some of the 1050 Winchester "sub-sonic" ammo. I can say that out of a AR 22lr upper with the 223 silencer, the action cycling is about all that you can hear.
The dedicated 22lr can was really purchased for my 6" Tactical Solutions Pac-lite, and with the velocities that barrel will run at I expect it to be quiet. Will have to get my old Glenfield mod 20 threaded or pick up a threaded Savage to use it on as well. The 22WMR mod 93 will need to be threaded as well. Maybe I need to figure out how to machine threads on dad's mini lathe?
