[QUOTE="Rich Coyle, post: 1289649, member: 70559"] For awhile back I made a recoil slide and started making brakes. I discovered the angled back are definitely better at recoil reduction than those angled perpendicular to the bore. I also discovered the ones angled forward are not as good as those angled back. One time my 'smith asked me to make one threaded on both ends with angled ports. I heard that only the first couple ports do any work so I made four ports. Of course the angled back reduced free recoil travel more than the forward angle did. After running that test three time in both directions I cut off the brake through the ports farthest from the muzzle. Following is the note from that day. Today, 12/13/14, I took the Savage with a Midway fluted 24" barrel chambered in .257 Weatherby. With no scope it weighs 6 lbs 5.5 oz. The load was Barnes TTSX 80 grain bullets pushed by 73.0 grains of IMR7828. The primer was a Federal 215 Magnum. The temperature was about 45 degrees. I fired three shots of each test. I decided to fired each subsequent shot where it stopped to get a total distance for the three shots fired. I used the new brake which has four .800" slots .100" apart that were cut with a 5/16" endmill angled 20 degrees to see if it was noticeably better than the one with four .750" slots .125" apart cut with a 1/4" endmill and angled 15 degrees. With no brake the total travel in the free recoil slide for three shots was 39 5/16”. With the slots facing forward the total for the three shots was 11 1/2". With the slots facing rearward the rifle moved a total of 4 9/16". Conclusion: Rearward facing slots are way better than forward facing slots. The shark gill brake allowed the rifle to move a total of 5 7/16".
