Took my AR and Howa 25-06 out to the range today with a few of the guys and forgot ear protection. I know, stupid of me for not making sure they were in the car and after finding out after a 40 minute drive, I decided to wing it for a bit. I started out with my 25-06 and it wasn't too bad on the ears but when I pulled out the AR, it was almost too much. Bad enough that I only put a mag down range and put it back in the case for another day. I'm no expert on ballistics or muzzle velocity or anything required to understand that stuff by any means but they seemed to be shooting around the same velocity (I think?) so why was my AR so much louder than the 25-06?
