some positive comments there, was thinking the little extra velocity will work better out to 1000yds than standard 260 windage wise,this will be my range rifle as is my 308, I intented using 139s,140s and 142,am still awaiting the return of my 6.5 06, hopefully I will get to shoot it on the 1st of september at bisley,I did it wrong way around really, should of had 308 rebarrelled but I had enough ammo to see me into next year so I had 25 06 done instead, if I was having the 308 rebarrelled into 260 for my hunting rifle I wouldnt bother with the ackley, barrel will be 26 inches at least
