Advanced Marksmanship Can you run 308 brake on 243?

[trauma1]

I have purchased a gen 2 little bastard in 308. I am building a 243 for competition.

Are there any ballistic problems with shooting a 243 through a 308 brake?
Thanks for your time.

There should not be any problems running a sub caliber through the brake. I have a .308 tbac brake on my .260 and run a .30 cal can as well on that brake. No problems at all.

I run a brake on my 260 that is made for a 308 and it has no issues. It still reduces recoil significantly and is just as accurate/precise as when ran without the brake.

I did same thing from .308 to 6.5cm . No problem.

I run just the opposite. A 223 brake on my 6.5 CM. I just drilled it out 0.015" per side over the nominal 0.264 bore size. If I remember correctly it was a size L drill. No change in POI and much less muzzle jump

I run .308 brakes on ALL of my rifles, .223, 6mm, 6.5mm, .284 and .308. Testing by Cal Zant of Precision Rifle Blog fame, has shown that loss in performance of an oversized brake on smaller calibers is only 2-3%. I like the convenience of having/using a couple of brakes like the APA Gen 2s on multiple rifles, or when changing barrels, regardless of caliber.

We get phone calls about this 2-3 times per day (usually about 6.5 through our .308)
yes, with No problems

Plain and simple...yup.

It is amazing that people continue to ignore the original post date...
