Re: Need Something Between 6mm and 270
Tim Tx, I suggest go with the 25/06AI as it has about 5 grains more capacity than the 25/284. This would be an advantage if you want to shoot the heavier bullets.
My 25/06AI with a 24 inch 10 twist barrel produces 3,580 fps with the 100 grain Nosler BT, 3275 fps with 115 Nosler BT, 3,225 fps with Wildcat 125 grain ULD, 3,150 fps with Wildcat 130 grain FBBCHP, 3,050 fps with Wildcat 142 ULD, and 2,830 fps with Wildcat 156 grain ULD.
My 10 twist barrel stabilises and shoots accurately the 125 and 130 grain Wildcats, but as anticipated the 142 and 156 grain bullets keyholed into the target.
My 7 twist barrel in 257Weatherby, stabilises and shoots the 156 grain bullet accurately.
Hope the above helps. Brian.
