Of course Mr. Graybeard knows this, but was waiting on Mr. Johnson to comment no doubt, but this bullet fired in the smaller 6.8
case & a 14" barrel to boot changes the performance dynamics of this bullet big time! The velocity difference would be huge, if started at 3,300fps as a 270 could do, your velocity at 300 yards or so would be the velocity of the 6.8 14" at the muzzel thereabouts. But the animal GB mentioned was shot at 289 yards, which would be the same as you shooting the Deer at 550 yards
or so as far as impact velocity is concerned. So for a 270 I fear you would be shooting a bomb, you could do lung shots, but why limit yourself & eliminate an angle shot opportunity if that is your only shot? I use a 150Nos BT in my Super14 30-30AI & at 2,400FPS
it works great but that same bullet at 3,500FPS in my 300Sendero will make sausage where I did not want it!!!
In shooting at a distance, the longer, heavier bullets with a high BC are the way to go for Deer sized game anyway. Trajectory is
easy to plot & knowing your drop is a must. If you have it plotted & use a rangefinder you have that whipped, if not then you would not need to shot the V-Max at distance either. Remember, the harder part is wind deflection & a high BC bullet will kick the Varmit bullets butt every time in the wind & arrive with more energy.
