Yeap they sure are loud. I have a buddy who has a boss on his 300, it barks and really makes the range guys glare. To be honest he doesn't really think it does a lot for accuracy, but it reduces the recoil for sure.

I was looking at a-bolt 7 mg but it had a boss, so I decided on a Rem 700 7 mg instead. I really didn't see the reason to spend the extra cash. I am a southpaw, so my choices were very limited. I didn't want to spend the bank on a gun that I sometimes don't even use due to other weapons/seasons.

I have heard magnaporting, acheives better results for the same or less cash. Honestly I don't know.

But what really p's my pal off is my gun shoots as good as his Boss. I did do a trigger job, which helps a lot.

If you like the gun and it has a boss then go for it. If it is something you don't really want or need, than just keep looking. It always comes down to personal choices and that should be the basis of a decision not brochures or others.

Good Luck.
