Both are excellent cartridges and I would bet you dollars to donuts that in the hunting fields of this world that nobody can tell the difference in trajectory or killing power..
Either one of these calibers would suit me just fine, I just happen to have an old .270 Win. Pre 64 Fwt. so I suspect I will just stick with it......
True enough. But I'll bet anyone who carried a 8 1/2 lb Winchester "Featherweight in 270 Winchester and then switched to a 6 1/2lb Kimber 8400 in 270 WSM will tell you there's a huge difference in how the rifles handle! This is a case where the rifles are more important than the chambering..............................DJ
I must admit I'm a sucker for lightweight rifles. ATM I shoot a R93 which only weighs 7.9lbs. It handles so well & is easy to carry throughout the hills.
I've had a productive year with my R93, but me being me, I want to get a new rifle to break the boredom of next years hunting session.
I will keep my R93, I love that rifle plus it's too much of a practical thing for me.
ATM I'm thinking Sako 85. I've had pretty good dealing with Sako's over the years. But saying that, the new FN Model 70 in either Featherweight or Extreme Weather has my attention!
So it seems from what I read here the 270WSM has 200fps over the 270Win.
I think a 140gr TSX would be what I would want to try, although a 130gr TSX would do the job nicely. Those 150gr TSX's look too long for the WSM. I know they work in the 270Win just not sure about the WSM?
Please keep the info coming
