Re: 264win mag vs 270wsm
The new 170 berger is going to completely change the 270s place in the world. Id keep the 270 and hope it will shoot the 170. Fast and light is fine for 400-500 yds but after that its all bc baby. Take the cash you were gonna spend on a 264 and develop a good LR load for that WSM. The only reason the 264 was ever even conceived was bullet superiority which it just lost.
Remember the advice you are giving that you got off of the internet and don't REALLY KNOW works might cause a miss or a wounded animal or a dead hunter. Please for the sports sake be 100% sure when you post something.
Per the NRA "long range STARTS at 600".
If your gun kicks get a brake....and some muffs. Unless your a masochist then its ok. Except you won't shoot as well.
