Anyone do a .338BR in an AR platform?

[amafrank]

Looking at doing up a .338BR for a friend who hunts hogs. He has been using a 30-221 bolt gun but has discovered that some of the hogs come looking for the shooter and others stalk the hunter. He wants more firepower and quicker followup shots so naturally the bigger .338 round makes more sense as well. I've got a RockRiver lower with all its parts and I'm looking at doing the upper. Any help on gasport size and location as well as loads for the gas gun would be helpful. I've done quite a bit of loading and shooting with the bolt guns but they don't care what the pressure curves are...just whats quiet.

Thanks

I'd be tempted to use a 458 SOCOM suppressed if the hogs are coming after him after being hit. An increase in .030" likely won't make much of a difference at subsonic speed, but a .458" bullet just might. I've got a bunch of 350 grain Hornady's and a nice wide meplat hard cast that I make that sits right at 345 grains. It's a gas-checked bullet, but if I were running it subsonic, I'd run it without one and send that puppy through a can!

I understand the Socom is a good round and the 50 beowulf as well but the owner has some bolt guns in the 338BR and is looking for a semi to use the same round. I just picked up a LAR 8 lower assembly from Rock River so I guess I'll stumble my way around and see if its doable.

I built one on the AR15 platform. Biggest issue was the 300g slugs fitting in the mags. AR10 would fix that. P mag worked perfect with the 225-250s I ran.

How about our 338 Thumper. It works great in an AR even with 300Gr. bullets.

Honestly after hunting pigs for over 25 years stick with the known, I suggest a 300 whisper/blackout/wtf with atleast a 220-240 gr or a 12ga semi cut to 18-20 and shoot sabot slugs through a rifled bore. I only hunt them in a stand or with dogs "curr/hound mix" as I am somewhat disabled and taste good to porkers or atleast my chunky wife says I do

If he is stalking as a lot of people do and can be legal and all I suggest a ar in 300w and a short as possible semi 12ga for backup. I can tell you from experience that it helps to have two, especially a 12ga that is good for 75-125 yds that shoots a heavy slug which will rip a pig a new asshole. Since using a 300 in a ar I have only had 3 run when shooting heavy bullets but they were miss shots on my end and could have been avoided.
