Which and why?

700yard limit
Whitetail , Feral pig, and some small (300lb) black bear.

Thanks

A 300 lb bear isn't all that small. The 270 WSM because it makes a bigger hole, not much bigger, but bigger. And the 6.5 will be a barrel burner. 130 E-Tips or 140 AB's

I was not sure if the 6.5 higher BC would help keep velocity and energy up at a longer distance. I understand the 6.5 is a "barrel burner" but would be used only for large game so it would not be shot a lot.

The 6.5 would have higher BC for a 140 bullet, but the 270 would get better MV. They would real close out to 700 yds.

I will probably be flamed for this, but why not a 6.5 vs 7? Don't get me wrong, the .270 is a great cartridge, but with the wide range of 7mm bullets out there, I just don't understand why anyone would want to go with the .270 caliber.

Me, I would pick a 7WSM or the 6.5WSM since you mentioned bear. Otherwise, the 6.5 would get my nod. Also, if you don't plan on shooting a lot, the barrel burning out is not a factor.

I have alot of 277 bullets from a 270 ihsma rifle I use for close range hunting. So I already have the bullets. Same goes for the 6.5 (I have a 6.5br). Never owned a 7mm as I have never needed one. Nothing wrong with them but just never wanted one.

I ran a quick JBM comparison and it really boils down to how hard you can push one or the other. If you romp on the 6.5 and run it 3200+ you start seeing an advantage over the 270 both with 140 Bergers, but it is very minimal at 700yrds. If I were targeting bears I would try to push a 150gr bullet out of a 270WSM.
I think the 6.5 WSM is cool but it would take more investment on the reloading bench and time to reload also. As far as bullet selection goes if you take a look the offering at best the 7mm may have one or two more bullets but in alot of selections the 270 and 7mm have three, there a alot of 7mmWSM shooter out there, I just hate anything 7mm due to some very poor terminal bullet performance, ballisticly it is real good by the numbers.
If you don't have 270WSM you owe it to yourself
