I have a standard .308 which is an older Omark with a 26inch barrel. (these have been used as fullbore guns in NZ and Aus for years). I was hoping to use it on game out to 700yards ish. I will be shooting small game (wild goats,wallabys) mainly. I have been told the 168gn A-max is a very good projectile. has anyone used this bullet? I was trying to stay away from Bergers as they are $90 for a 100 pack and Im hoping to do alot of shooting and I dont have alot of money.
I made up some 150gn FMJ the other day that I was given and shot two 1/2 MOA groups at 100yards and shot a few rabbits at 200yards(My brother shot a hare in the head at 220yards) so the gun shoots ok just need the projectiles.
I think the twist is 1 in 13" or 14". im not sure and will check it when i get home. The barrels are made to shoot 155gn as these are the heaviest you are alowed in fullbore shooting.(thats what I understand anyway). would the 178gns(BC 0.495) work?windage for 178gns 5.28MOA. windage for the 168gns(BC 0.475) 5.27 MOA.
That was useing 2750fps for 178gn and 2850 fps for 168gn and 10mph wind..
I just sorta made up those velocitys and put them into a programe to get an idea of the windage. are those velocities realistic? thanks for the help I didnt realy consider the heavier bullets as i thought they would be too slow.
both loads have about 1000ft.lbs of energy at 700-750yards which is heaps for a goat.
