I am a newbie to this forum. I have been looking into magna porting my 7mm rem and 30-06. They (MagnaPort) are still in business. Question: how is a brake different than MPing? Weight?
Yes use hearing protection. Twenty three years in the military helped me loss hearing and develop tininitis.
I brake doesn't add any weight. Some weight is reduced because of the slots created on the sides of the barrel. Very minimal though. For me, the Magna Porting completely made my elk rifles, much more comfortable to shoot. However, I think max results would be achieved with a brake.
