I recently bought a Win 100 in .243win.The problem when i shoot it while hunting (without ear protection) it is VERY loud.After shooting it my ears ring for 3 or 4 days after.I've hunted with a few different guns for over 30 years,levers,semi's,bolts,.243,.308,30-06,300wby mag, and NEVER had a problem like this.The gun has a non factory stock.I'm wondering if the stock is affecting where the action blowback noise is going(directly to my ears) or if these guns are inherently very loud to the shooter.When i shoot near other people(sighting in) nobody tells me that it is louder than anything else.Any help with this problem is appreciated.

I hunted with the M100 Carbine in .308 Win for years & had no noise problem.

I have a Model 100 in .308, it's no louder than any other .308
