OK but what about the .391 Skyripper WSSM Aptly Improved version? It got 9'& 1/4" penetration making it FAR superior to the non improved version. AND it has 43 times the powder capacity of a .270 with less recoil!
Also if you reload you can get the cost of each shot down to only $54.39. I can't see how you could possibly argue that a .270 was better after all it's old and obsolete.
Once you add in the auto range finding, laser guided, trajectory correcting 18X63x88 scope by Trashco you can shoot Niowts at over 3674 yards. I know a guy who did it, off hand.
.270's are mostly worthless now.
