[QUOTE="Guest, post: 35649"] 7ultra, Depending on the manufacturer of the brass: 7.5x55 = 65.0 284 Win. = 66.0 308 Win. = 56.0 30-06 = 68.0 The 7.5x55 SM (Swiss Match) is already an accepted target cartridge used frequently in CISM target matches so it is a good candidate for tactical use, also. It's accuracy ability is without question. The ballistic performance should be right along with the .284 Win. given the same circumstances and similar components. I didn't hesitate to go with the .284 Win. for a chamber instead of the 7.5 SM due strictly to the availability and cost of brass, ammunition and dies. The performances are equal for the most part and the greater expense for the Swiss pushed me towards the Win. The basic .284 case has been proven in competition already with the 6mm and 6.5mm x 284. Brass is available from Norma, Lapua and Winchester at least. The 7mm line of bullets is terrific for both hunting and target (tactical). Any of these 4 cartridges will perform admirably in a tactical situation and either the 7.5 or the .284 can certainly be considered to be tops for your needs. I understand the desire to have something that might be considered to be slightly different from the rest. Regards. [/QUOTE]
