As far as I know, they only major difference is the stock.Just curious, is the stock the only difference? Is the action,trigger and extractor are all the same as well?
I like a flat trajectory where you don't have to worry about any kind of hold over at any range where it is reasonable to shoot big game. I think if you have 1500 ft-lbs of energy or more at the target distance you have more than enough to dispatch a moose, providing you have a good bullet that expands but holds together. Because a bullet expands so much I don't think the initial bullet diameter is a significant factor. How much it penetrates etc. is primarily based on the bullet design and energy available at impact. The old Nosler partition bullet is my favorite for moose, and I have taken a number of them with a 140 gr. in my 264 WM. A Nosler 140 or 150 grain in a 270 should be just as good.Just curious Ron, why would you pick a .270 over a 30-06 for moose? I actually traded in a .270 for a 30-06, because the 30-06 will shoot 220 grain bullets, while my .270 didn't shoot well with anything over 140 grains. Maine moose are big, and I didn't feel confident taking one with any bullet weighing less than 180 grains.
I'm certainly not questioning that the 270 win will kill moose or elk with a well placed shot. But I think you will find that the 180 gr 30-06 bullet retains velocity better than a 140gr 270win. Hence, the 180gr 30-06 penetration advantage increases at longer distances.It is a tradeoff between a .270 and .30-06.The .270 has higher velocity and smaller diammeter bullet and will penetrate better but the -06 can use a heavier bullet and will penetrate better at lesser ranges where it has velocity.Here again,I know because I have seen it done that a 140gr bullet in .270 will put a moose down fairly easily,I personally would rather have a 180gr bullet in an -06 which I have seen put elk down but never saw used on moose.A 220 in .06 just doesnt get it. sam.
