[QUOTE="Cordell, post: 455206, member: 15433"] Trueblue and Coyboy I understand now. I just measured the hole in the last port/baffle, it is .0367 and I'd guess the first one is the same. With the first one being so close to the muzzle the back pressure is causing the kick. The gas is being forced through a small hole causing the equal and opposite reaction, the gas is being trapped in the first chamber and is not being allowed to escape fast enough. I am getting excited to get this done, then get the beast out to see if it has been tamed. I will have to look at the brake on my 300 RUM and see if it could be opened up to help reduce even more kick. What size do i want the hole to be in the rest of the baffles? Mine is .0367 wich is very close the the maufacures recomended size of .0368 for a .338 bullet. I know the ports on my brothers are bigger than .0368. Also do you want the holes to be smoth? Mine looks as if they have been threaded or like a dirt road turned on its side and you can see all the washboard ruts. Now I have another question, would this hole in the baffle being so small, slow the bullet down at all? As the bullet is traveling down the barrel it has to push the air out of its way. Will this also cause some back pressure slowing the bullet all be it a small amount say 1-15 fps or so? I wouldn’t think so, but as I stated before I don’t have much knowledge when it comes to brakes. [/QUOTE]
