just took a Weatherby mark 5 rifle and rebarreled with a 4 contour , 7 1/2 twist , finished at 28 inches ,chambered in a 257 Weatherby mag. cartridge , Brux barrel , i built this to shoot the 135 gr. Berger bullets ,Hammer bullets and maybe 131 gr. B.J. bullets too. have not shot it much hoping to get 3300 + fps with good accuracy. i do know my 257 Creedmoor really shoots well out to 500 yards and rifle has a Brux barrel 7 1/2 twist barrel too. this new rifle is for any range antelope and deer , i have shot some antelope and deer in the past with just a Brux 10 twist barrel 100 gr. Nosler partition in a 257 Weatherby mag at 3800 fps a long ways out on the first shot already but hope to gain just a little more. hopefully ? i feel the 25 caliber rifles should come with a 8 twist barrel not a 10 twist , i also rebarreled 2 - 257 Roberts rifles with 8 twist Brux barrels ,both these rifles shoot really well with 115 gr. and 135 grain bullets these 2 rifles are for the family ladies to use also. good luck with your 25-06 should be a good long range shooter too ,Pete53
