[/quote] I install KDF brakes and have had nothing but positive comments from customers.. FWIW.
I'm not one of Redneck's customers, but I have KDF brakes on my .375 RUM and on my .300 Weatherby, and I would never even consider removing them.
Before I had the KDF brake installed on my .375 RUM, I couldn't even shoot it enough to work up a load for it. With the brake I have easily worked up sub MOA loads for it with 300 and 270 grain TSX bullets and with 300 grain Partitions. I've taken this rifle on two African hunts and have killed animals from Steenboks to Buffalo and Eland with it, several from prone positions, and at ranges from 30 to 350 yards.
I had the KDF brake installed on my 300 Weatherby before I fired my first shot with it, and it quickly became my favorite rifle. With the KDF brake it kicks less than my 308 Win in a similar rifle. I have developed sub MOA loads for it with a variety of 168 and 180 grain bullets from Barnes and Hornady. Since I built this rifle in 2009, it has been my 1st choice rifle for almost all of my hunts and it is my favorite rifle to ring the gongs at our local range.
