O.K, thanks to all.
I'll try to make an accurizzer first for my remington vs sf 223 and lather, if it works, for my sauer 90 7 rem.mag.
I went for hunting two years ago in Wayoming and in colorado with a friend of mine, an old vietnam sniper, Richard Sals. He used a browning bar in 7 remington magnum with a muzzle brake like a boss and shoot very well ( I used a remington 270 of an other friend, but I don't like this caliber ).
Now I'll write to Cristopher Long (http://www.the-long-family.com/OBT_paper.htm
) because I don't understand why he do not consider the weight and the diameter of the barrel in his formulas, but only the lenght. I unfurtunately am not a musician, and spent a great part of my life studying neoplasm, but the same I think that a large barrel and a thin one of the same lenght cannot vibrate at the same frequncy..
P.S. BuffaloBob, I escuse your English. Even in Italy we know that in alabama bray and speak only somethimes...:-)
