I'd assume your suppressor is .30 which means it would work with a wide range of calibers. Honestly, if you're just deer hunting in MS I'd go for a .308.. more rifle options, suppressor would work with it, cheaper ammo, etc. If you're dead set on the 6.5 I'd go with this...
Pistol: west german p226 in 9mm
Rifle: This is a really hard one.. I narrowed it down to my DD MK12 with a 1-4 on it or ruger scout with a 2.75 burris scope. Probably take the ruger just because .308
Shotgun: 870
I agree with the play on words that's why I put minute of man in quotes. My only point was that in general ARs are not inaccurate even though unfortunately many people believe that. But to be fair you and I could define accuracy completely differently. If you fire your deer rifle from a bench...
This is just 100% completely inaccurate and misleading. It was designed with the average draftee in mind in the mid 60's to shoot 'minute of man'. Any modern AR is going to EASILY shoot 2 MOA which is extremely effective for shooting deer out to 250 yards. The truth is the majority of ARs today...
And this feels so ignorant. An AR-10 or an AR-15 chambered in 6.8, 6.5 Grendel, even good ole 5.56 nato could possibly be one of the best rifles for deer hunting in MS. Where I live you will not take a shot over 150 yards. I'd prefer a light rifle with a low power optic on it coming in under 7...
If you're going for the most quiet setup skip the AR altogether. Get one of the many bolt action .300 blackout rifles out there with an Omega on the end. I have a ruger American in that setup and it's whisper quiet. The 220 grain bullets hitting the target is the most noticeable sound heard.
.308 hands down no other argument for your purpose (ok that's a little much) but if it will solely be a deer rifle I don't see any reason not to get a .308. It's probably the most popular caliber in the US, you will never have trouble finding ammo whether that be practice or hunting rounds, and...
That guy had one of the most embarassing internet freakouts I've ever read over a tv show over there. I look forward to his posts when the hammer falls
