![]() I was alone so I did not have anyone to validate whether it was louder to the sides but I would be willing to bet that like all brakes it is. I was wearing muffs and plugs, as I always do at the range and I did not notice any increase in perceived noise from the brake. I checked the bolts after 20 rounds and found no decrease in torque. There was however carbon buildup on the barrel and brake as the number of shots increased. I checked the brake after the first shot and every two or three thereafter and there was no indication of baffle strikes, as it should be. The gun felt like something between a 223 and a 243. There was however a VERY noticeable reduction in recoil and muzzle jump. Both loads shot just as good as before, making 3 shot clover leafs at 100 and under 1” at 300. With the bake on there was no difference in group size or shape at 100 or 300 yards. (Both of these loads are pushing the 162 grain Hornady bullet north of 3300 fps) It took two shots to get the gun hitting 3” high, dead on the line at 100 yards. With everything mounted and two loads that I know shot well in the RUM, 162 BTSP with 84 grains of 7828 SSC in Rem brass with Winchester mag primers at 3.60 LOA, and the same with 94.5 Grains of Retumbo, I headed to the range. ![]() In addition to the brake, I had also mounted a new Leupold 4.5x14 B&C reticle scope for an upcoming antelope trip so the gun needed to be sighted in as well. I figured this made it the perfect candidate to try the Kahntrol Brake on. ![]() In fact I have never shot any other gun that was as nasty to shoot or kicked as sharply as this 7 RUM out of the box.Īfter installing a Mercury suppressor in the stock and a Pachmeyer decelerator pad it was comfortable to shoot but still had a very brisk recoil and quite a bit of muzzle jump. (To be fair both of those are quite are bit heavier and the 460 has a brake on it). ![]() It was far more unpleasant to shoot than my 375 or even my 460. Not really surprising when you figure you are burning 95 grains of powder behind a 162 grain bullet in a gun the weighs 8.5 lbs with scope. It didn't really recoil in the traditional sense, it was more appropriately described as a REALLY SHARP punch that even with lots of padding would give you a headache after 10 or 15 rounds. This 7 RUM is my all time least favorite rifle to shoot out of the box. The one thing I did different than the instructions was torque it down to 50 inch pounds rather than the 30 recommended. I could have done it faster but I was quadruple checking everything and being very careful to ensure everything lined up perfectly so there would be no chance of baffle strikes when fired. I followed the on-line instructions and had the brake mounted, levelled and timed in about 20 minutes. The brake was very easy to mount on my Left Hand 26” all Stainless Remington 700 in 7 RUM. Very similar to a set of scope rings but over a much longer opening. Kahntrol accommodates the wider range of barrel sizes by having 6 vertical tightening screws along a horizontal split. This makes fitting them to any other guns unlikely. All of the other brakes were cut for the exact muzzle diameter of the specific gun barrel, accurate to. ![]() It means I can use it on more than one gun. One of the big reasons I chose the Kahntrol was it was the only one that was able to fit on a fairly wide range of barrel sizes, in this case from. Grizzly Exact fit to barrel measurement $235.00 Canadain Witt Machine Exact fit to the barrel measurement $89.00 U.S. It was however quite a bit more money than the Witt Machine brake. Even with exchange and postage it was cheaper than buying the Canadian equivalent. After looking at a number of Clamp on brakes I decided to order the Kahntrol brake. ![]()
