Proof Research Barrel Length

[bjw182005]

I am in the process of working on a build using a Proof Research barrel in .308 and looking for some opinions on barrel length. I plan on using this for general long range shooting and the occasional (hopefully frequent) PRS style match in the Tactical Division. Looking at lengths between 20: and 24". What are your opinions?

I have an FN SPR with a 24" barrel that is a great rifle, and cutting some weight using a nicer Manners Stock and Proof barrel should make it a little simpler to maneuver with, but what do you think is the best overall compromise on muzzle velocity, accuracy and maneuverability? I am currently thinking 22". Thoughts...??

I would go 24". Still easy enough to get around with but a little more velocity.

If it were my only rifle, I'd go with a longer barrel.

.308 and a Proof, go long. 24-26". You'll be no worse off than guys running 18-22" with a can.

 

[wapiti16b]

24"s and a can !

24-26". You won't be fighting for velocity.

This right here, and you can even add a can of decent length and still have good mobility.

I don't think the 24" barrel would hinder me in any way as it is what im used to from running my SPR.

Is there enough of a velocity difference between 22" and 24" that it would be detrimental? More so curious. About to pull the trigger on the build and want to make sure I go with the best possible option. I wont be a serious competitor or contender most likely as I am military and frequently deployed, so its more to continue to hone my skillset and train.

I was curious about how much velocity drop going from a 24 to 22" barrel after reading your question. Turns out not much, around 38 ft/sec for 168 grain Federal GMM (see link for more info).

I just bought a Barrett MRAD 300 win mag with a 24" carbon fiber barrel from proof research and it is awesome, the rifle is lighter and it looks bad ass.

Yell it from the roof top, brothers in arms!

Normally you loose 25 FPS with every inch you chop off or don't add. I think 24" barrel all the way.

I decided to go with the 24" Proof barrel with the Area 419 Hellfire Brake. Im hoping the combination works well. Ill post some pictures of the build once I get it in hand. I will have to get back from this deployment first, but Ill try to remember.
