I have two .222's and a .223. Noise is the same.
[qb] I currently own a Weatherby Super Predator Master in .223 and like the round, but I recently acquired a Blaser R93, which accepts multiple caliber barrels. My intent was to sell my hunting rifles and have one gun with multiple barrels. I have a choice between .222 or .223 with the Blaser. I hunt in a semi-residential area and I'm concerned with report noise. I noticed the .222 round itself does not measure up to the .223 ballistically, but does that mean it possibly quieter? Thanks.
