Breaking a .308. Muzzle velocity questions.

[SquidHC]

Looking at purchasing a Rem 700 SPS AAC. This rifle comes with a 20" heavy barrel that is threaded for a break/suppressor. Since a suppressor is not in my near future I would put a break on the rifle. Keep in mind that I am a beginner shooter and this rifle will out shoot me for a while. I would also like my 12 year old to be able to shoot this with me.

I have the following questions.

1. Would having a break installed reduce the velocity of the bullet enough that it would cause notable issues out to say, 600 yards max?

2. If so, should I be considering a model without the threaded barrel?

3. If so, would you go with the 26" standard weight barrel or the 20" heavy barrel?

1. No reduction in velocity, 600 yards easily reachable.

2. Go threaded, gives you options.

3. You'll be happier with the 20" heavier contour.

Why isn't a suppressor in your near future? There is a great group buy going on with them right now, $600 for a TI suppressor, very cheap. Your 12 year old will thank you!

1. no
2. see 1
3. stick with what you have. A muzzle brake with a heavy barrel equals a light recoil gun. should be easier for both of you to shot. You can get a vias brake and just screw it on. ver easy install.

Re: Breaking a .308. Muzzle velocity questions.

A brake will not effect velocity as the bullet has already passed the crown and the gases, essentially allowed unconfined expansion, will no longer be significantly pushing on it, brake or not.
If you want the AAC get it, I don't find a brake neccesary on a .308Win, others do. If you're interested in shooting bullets over about 180gr the 1:10 rifling will likely prove beneficial. Just because the muzzle is threaded does not mean you must mount something on it.
To 600yds and beyond 20" is fine, 26" will just do it with a bit more velocity and a bit less drop, the difference is more evident as range increases. Either way if its primarily a range or competition gun I'd go Varmint profile, sporter profiles are better suited to lower count shot strings.

Because $600 for the rifle, $650 for optics, $100 for base and rings, $100+ for bipod, and probably $100 for a break = way more than my wife will be happy about as it is. Even if I did order that suppressor (which I would love to do) it would probably take 9 months ATI processing and such.

This rifle will be multi use. It will see the range, but also probably see some hunting action. I'd love to shoot some tournaments but I don't know the first thing about that.

Go for the suppressor when your ready. I'd have a couple already but I live in NY.

I've got the same rifle. I put an RWS brake on it, (RWS, the member here not the business). I've yet to shoot it with the brake as now my bolts off to Monteyboy getting a knob installed.

I've got the same rifle with a surefire break. It has no affect on velocity but makes a difference on recoil and hit id/follow up shots. I use mine for target shooting to 1000 yds and hunting in the fall. It's nice handling the shorter barreled rifle in the woods/stand/blind. Also with the break my son who is 8 can shoot it without complaint of recoil.

Re: Breaking a .308. Muzzle velocity questions.

stated already, no a muzzle break will not reduce velocity. Get a threaded barrel. I would suggest a 20 to 22" barrel instead of a 26"...that will give you enough to reach out to 1000 yards.

For threaded muzzle breaks, I like R&D or RAD brakes.

I prefer having a muzzle break to spot my own shots.

Re: Breaking a .308. Muzzle velocity questions.

It's pretty cool to watch my shots strike the target. If I were you I would consider looking at a new stock for that rifle. Noticeable difference in accuracy, which helps hitting your target at 600yds more consistently.

1: 600yds isn't a problem for .308win. Brake or no brake.
2: Having it pre-threaded is always cheaper.
3: velocity loss from 20" isn't bad. my aac-sd sees 2580avg out of fgmm 175smk.

number9; I have the same brake on a savage 10fcp 5r and it feels like a 223.
