Short. 308 idea

[jaime1982]

Hear me out.

Wanted a short 16" .308 for a suppressed scout, blind gun. All I could find was a 20" so I picked it up. It's a remington 700 sps tac 20inch.

Now I'm considering my options on cutting the barrel down and having my yhm phantom qd pinned and attached permanently. The qd is about 3 inches long.

Plan to shoot 150grains 200yds or less. Usually less

Here is a ballpark of what I'm thinking of......opinions? [emoji848]


Pic 1~24" total

Pic 2~22" total

Velocity and 95% burn.

Only thing to consider would be velocity if it matters. I think the shorter the better but only shooting 2475-2480fps with 168 FGMM out of a 16.5" SPS AAC with a 8" Griffin can.

Short. 308 idea

If going to permanently pin then why not go shorter? Say 14-16” and suppressor break would bring to 16”+?

That's how it's lined up. All approximate of course.

13inch would get me to 16 inch, 22inch total

15inch would get me to 18inch, 24inch total

Remington makes that rifle in a 16.5" as well. I know you said the 20 was all you could find but if you could live with 16.5 and you're not in a hurry I would wait til I could pick one up and then sell yours. Would likely still come out a good bit ahead in $$ than spending to have yours cut.

Yep, can't find one for a decent price. I'd also take an ugly 783 or a cva type but can't find one either.

I have the R700 16.5 aac-sd in 300 blk and a R783 16.5 in .223, all I need is the 308.

Also this rifle will be shorter as I'm using the qd to add 3inches as it will be permanent.

Pic 2 is what I would do in your spot. I have a 14" contender barrel I am going to have cut down and sbring the pistol frame to make a little suppressed .308. Barrel length will end up at 12" after cut down and will be 19" long after threading a can on it. I was planning on running 125 gr loads to get me out to 300 reliably.

I say if short is what you are after i say cut it as short as you can get by with and let her rip.

If you willing to spend the $, TBAC has a pinnable direct thread and then you can cut to 10” and pin a suppressor to it. I would go shortest your break will let you as don’t think you loose much and gain maneuverability.

Pic 2 is the shortest I can go. About 13inch usable barrel and the 3inch qd mount will get me to 16inches.

I don't think 2-3 inches would be worth pinnning. Either SBR it or don't. If I were that concerned about OAL vs velocity I'd be looking at 12" with direct thread, but I understand the mental debate. 1st world problems for sure... I like it!

[BLACKFINTURKEY]

I was in the same boat. I went 16 only because I didn’t feel like paying a dang Sbr stamp.
FYI I’m still getting 2700fps with 178s with the can on.

I agree shorter the better. Unless you want to shoot far.

[BigJimmyRustler]

I've had one gun pinned and welded, sold it and doubt I'll ever have another.
Granted, mine was an AR but it's still a PITA.
To me its either worth it to SBR it (brace it if possible) or keep it 16" (or longer).
IMO for what you're gonna use it for I don't think that little bit of extra barrel length will be too big of a burden.

Most any load I see with a 178gr Hornady pushes them at 2600-2700 with 24-26 inch barrels. What powder and charge weight are you using to get 2700fps out of a 16 inch barrel? Ever shoot that load on a hot summer day?
