Rem 700 5r Stabilize 220g SMK?

[rjacobs]

I have tried searching every possible way from Sunday on this with no real results.

I am back in the bolt gun building mind set. Its going to be .308. I want to be able to shoot up to 220g SMK's subsonic through a can.

I am going back and forth on a 700 AAC with the 10 twist barrel, spending a little extra on a 700 5r with the 11.25 twist barrel or having a gun smith build me what I want from scratch with basically a stock rem 700 action, but with a higher quality 10 twist barrel.

So back to the question at hand. Can the Rem 700 5r stabilize up to a 220 SMK? I would probably also be shooting Hornady 208g AMAX and 225g Match.

Not reliably.

... and I'm not sure why you'd want to be shooting such heavy pills in 308 unless you are going subsonic, in which case a 11.25 twist will definitely not stabilize a 220SMK.

I think you missed the part in my post that said "I want to shoot subsonic through a can" so yes subsonic is my intent, but I also want to be able to shoot supers obviously.

I did not think the 11.25 would stabilize it, but I coulda sworn the couple guys on here(pappabear) have done it with success, but maybe the highest they went was 208 AMAX or even some of the 190g bullets.

Like I said, tried to search, but came up pretty empty.

Guess its on to seeing what the gun smith can come up with in 10 twist barrels for the .308.

Shoot 175 SMK subs like the rest of us. 3 mil come up at 100 yards give or take.

We ran them out to 300 yards last weekend.

I've shot subsonic 308 extensively, and you won't even be able to get a 220 stabilized in a 10 twist barrel, much less a 11.25.

Why you think 300BLK has 1:8 or 1:7 twist? It's designed for the 220's, with the 1:7 being able to effectively stabilize the 240's while subsonic.

Now you CAN run 220's out of a 10 twist 308 at full speed. I wouldn't... but you can. This doesn't mean your specific barrel will be able to do it. It just means that most 10 twist barrels can do it.

In a 10-12 twist 308, you won't want to go any longer than 175SMK with subs. You might be able to get away with 190's... but I wouldn't take the first shot with the suppressor on. Run sans can and shoot through thick paper up close to see if the holes are round before sticking your tax stamp on the end.

I reiterate: You do NOT want a 10 twist for subsonic 220SMK.

...baffle strike. OP watch for keyholing.

Cheapest way to shoot 220 subs would be buying a Handi Rifle in 300 blackout (1/7 twist).

Those are pretty fun. No doubt about it.

I prefer a bolt gun though. DTA Covert with 16" 1:8 launches 220SMK's like guided missiles, and it's shorter than the handi-rifle.

Ive got a full 300blk SBR already with a 9" 7 twist barrel so I am setup there. I am wanting this to be able to shoot supersonic long range 308 mainly, but obviously having the can I want to be able to load up subs and shoot them too. I guess I gotta get out of the mindset that subs HAVE to be the ridiculously heavy 208 or 220+ projectiles like they have to be in 300blk.

I picked up 600 175 SMK's last night at Cabela's.

If I can find a 700 AAC for the 650 price point I will probably grab it. I have a local guy who says he can get me a 5R with 20" threaded barrel for like 1100+tax, but I think I am going to attempt to find an AAC for a decent price before I go that route. That extra money damn near gets me a chassis.

I have also shot my R700 AAC (1:10" twist) extensively using subs and an AAC can. My recipe has been 220 grain SMKs pushed by 9.8 grains of trail boss. I'm not sure where this assertion it won't work is coming from? When you run the stabilization calcs online it even says its stabilized. I'm about to start testing with my 5r 1:11.25...but no can at first.
