I have this Pre 64 Mdl 70 30-06 that I’m going to re-barrel and was going to leave it an 06 because of the mild recoil and it has sentimental value. Got reading about the Ackley Improved version and kinda like that. I all ready have a Brux 30 cal barrel so there is really no added expense to chamber for the Ackley. If you compare the standard 06 using the Nosler Reloading Guide you can see an increase in fps of 100 to 120 depending….. Now the test rifles used a 24” barrel so if I leave the new barrel 26” do you fellas that know think I could pick up another 50 fps giving somewhere between 150 & 200 fps total increase over the standard 06? Also wouldn’t the head spacing be more consistent because of the 40 degree shoulder thus making a more accurate rifle? I know and understand that’s not much but it would increase the usable range by 100+ yards and it would be a solid elk getter at 700yards using the 200gr Accubond.
