I've read from numerous sources that the PTR91/HK91 rifles are very very hard on brass. The violent ejection of the casing and the impact of it hitting the receiver while exiting the chamber leaves a dent in the wall of the casing from the pictures I've seen. I understand that there is a port buffer (I think that's what it's called) that helps prevent this, however I've not seen any comparison pictures between casings fired with and without the buffer.
Does the buffer completely eliminate this problem with the rifles being so hard on brass, or does it only mitigate the problem? .308 can get very expensive, so if I can reload my own ammunition, that means I can spend more time on the range, rather than at the office trying to fund my ammunition bill.
