My only thing is that I have never gotten the idea that a .308 or .270 is a pussy cat to shoot and a 30-06 is a monster. Load a 150 in all of them and I can't tell the difference. Actual recoil in all of them is negligible to me.
^^^This!
I can tell the difference between a 130 Grain 270 factory load and the same brand ,shooting the same brand/type of rifle 30-06 150 or 165 grain at the bench or practicing offhand ,kneeling etc.
Yet the 270 130 grain seems to kill deer Just as well as the 06 with 150 or 165 grain.
It should as the Ballistic coefficient of say Sierra Boat tail bullets are listed as
.277 SBT BC-.436 SD-.242
.308 150 grain SBT BC-.380 SD-.226
.308 165 Grain SBT BC-.404 SD-.248
Using the data here it can be seen that the 270 Winchester .277 130 grain bullet better compares with a 165 grain bullet .308 bullet. A bit flatter trajectory,a bit less wind drift ,a bit higher velocity,Quite a bit less recoil using the 30-06 165 grain as a baseline.
30-06 is a great round and I have killed more deer with it than any other round BUT for deer size game the 270 Winchester is a BIT better.
I really wouldn,t feel under gunned shooting the 30-06 compared to the 270 .
