[QUOTE="Tata Tibor, post: 1508258, member: 55256"] I am absolutely not claiming to be an expert, but I remember few years ago to come around an article (by one of ballistics experts) where the author published results and table of extensive testing what is optimal for which caliber. Since one of my rifles is 300WM I remember that optimal was barrel 1:9 and length of 26" to 28". Optimal bullet grain 210. Unfortunately I cannot find it anymore. I as looking for it for awhile because it listed cool tables and graphs to figure out optimal combination for any caliber. Now I am just guessing for my other rifles what is optimum, and painstakingly testing at the range. Just for a kick of it 7mm RM is 1:9.25 and 168 grain. [/QUOTE]
