Muzzle Brake Thread and Size

[Lou Tenant]

I have a Remington 700 Long Range in .300 win mag. The muzzle measures 0.808. what size diameter and thread size should I order? I did a search and I didn't see any questions with the same diameter muzzle. After researching, I thought I wanted 5/8 x24, but one vendor recommend an 11/16 x 32. Now I'm a little confused. Any suggestions would be appreciated.

Thanks

Both of my 308's are 5/8x24

I've never owned anything (besides an AR) with a brake so this isn't my suggestion but.....

Do a 5/8x4 especially if you want to turn a brake flush with the barrel OD.

I'd put a 3/4-24 brake on. More meat you leave around the bore, the less likely you are to have an affect. Professionally installed brake from IdahoCTD is my recommendation. I know his recommendation of 5/8 is more common.

I always leave my brakes fat on the barrel just because of that....

Thank you for your responses. The article linked above was very helpful.

I did a 280 AI with a 5/8-24 and I used that thread for my 6.5saum also,
dang I hope i don't get the trombone effect

Lots of them done in 5/8 and most have no problem. I just use 3/4 whenever I can to add insurance. Also, both of your bores are smaller than 308.

I think I'll start using a 13/16-32 for mine because that's the one I used for my tuner.
now my OCD is telling me to pull some barrels and start rethreading

Thanks I figured I was probably good

I was just thinking I need some deltonic or deltronic? pin gauges and realized I have some 7mm bushings that will tell me if I have any flaring.

Hmm maybe a 3/4-32 Would be more suitable for all my purposes?

The number if threads per inch isn't important. The finer the threads the harder it is to time because it rotates more degrees per thousandth. Not a big deal if you buy one of the timeable ones. The thread pitch is chosen by the muzzle brake manufacturer and the smith just matches it on the barrel. --Jerry

Yes I haven't needed to time any yet. I've been thinking about a harrels though.
I have been getting smaller bored than what it's going on and smaller threads and reboring and threading to what I want so I know it's true to the bore and the thread i wanted also.
Thanks

What do you think about 3/4-32 for a tuner or brake?

Op Sorry if I slightly derailed the thread

if you've got a brake threaded in 3/4-32, then the thread is just fine. It is no harder to cut 32 tpi threads than any other. you may have to custom order your brake unless a manufacturer has recognized that tuners are using that thread and started making them. --Jerry
