I plan on buying one of those Bushmaster .450 thumpers for hog hunting.Well that is the excuse that im telling my wife anyhow.Any of the said calibers will work fine.
That sounds like a good excuse. Everyone needs a 45cal AR. I'm leaning more to the Armalite chambered in 338 Federal. I already have a bolt gun in same caliber and absolutely love it.
