[QUOTE="freddiej, post: 1766224, member: 26227"] If no one has mentioned it yet, I have found one great way to mitigate barrel whip and harmonics. A muzzle brake. I have two really buggy whip barreled rifles, they were 1.% or greater guns. after hand lapping they were better but not much, so I went to a guru of muzzle brakes, had both of them fitted with muzzle brakes. instantly went to the range and put the exact same ammo down their pipes and was shooting under 3/4" out of each. those of you whom know me know I never use Center to Center as my measurement. it's always edge to edge. That is if I do not specify C to C after the measurement. the first of these rifles is my 270 Win M-70 featherweight carbine, the other was recently sold to a friend, it was an M-70, 25-06 featherweight. Those limbsaver vibration rings do work I am told, but none of the people I know that use them have ever given me data like before and after installation. so I can not say if or how good they are. I know one more way of mitigating barrel whip and harmonics, counter lands and groove rotational fluting. don't ask me how this works but it stiffens the barrel and kills much of the harmonics. I had a barrel fluted this way for a client. I shot it before and after, the gun was almost 2 pounds lighter and it shot 1/3 the size of the previous groups. same ammo, same lot, same temp. it also made the gun look very nice with the CeraKote camo pattern on it after the flutes were milled. just my 2 cents worth. later tatters.
