Quote: The 270 WSM offers a SLIGHT improvement over the old 270 win, but not enough that either you or the game you are after will ever notice the difference. Using the standard 130gr bullet, the WSM beats the standard 270 by about 200fps, and at 300 yds, the wsm drops only 1" less than the standard 270.
I own both a .270 Win and a .270 WSM. I use 140 grain bullets in both since I consider that to be optimum for the caliber. My .270 Win will give not quite 2900 fps with accuracy. My Savage in .270 WSM is capable of almost 3400 fps with Magpro powder and a 140 Accubond. If you look at the ballistics of the two loads , 500 fps difference is very significant both in KE and bullet drop at longer ranges. It's funny how people can make broad statements when they don't have their facts straight !!! Run the numbers using a 140 Accubond and the two different velocities. Sighted in for Maximum Point Blank Range, the .270 WSM is good for another 50 yards. That doesn't really tell the whole story. Sighted for max PBR, the .270 Win is 10" low at 375 yard. Also sighted for max PBR, the .270 WSM doesn't drop to 10" low to almost 450 yards. Big difference, at least in my book !! Energy with the WSM is 3595 and .270 Win is 2615.Nine hundred and eighty (980) foot pounds is very significant no matter how you slice it. It turns a .270 WSM into a legitimate elk round, plus gives you some margin for error with the energy on a really long shot. Did I mention the superb accuracy?? Mine gives me .3-.6 MOA consistantly. Can you tell I really love my .270 WSM ?

Thanks all for the great info. The point of this thread was not "is this better than that" If I wanted to know if the 270 WSM was better than the older 270 win I would have asked that I have only herd very little about the round and wanted to ask if anybody has had any luck with it good or bad. Sorry to upset any of you out there with my "is this better than that thread" but again thanks all for the good info.

I see no reason to use anything less than a 150gr partition in the new WSM, velocity will still be very high, will deliver plenty of energy and a well-constructed bullet as far away as most people can shoot. I think it's a good round for a lightweight mountain rifle for anything in North America shy of the big bears.
My Savage in .270 WSM is capable of almost 3400 fps with Magpro powder and a 140 Accubond.
Key word is "capable" The old .270 is capable of rediculous velocities also. Dosen't mean they are safe. My .270 WSM is capable of about 3200 with 140 accubonds out of a 24" barrel with magpro before my caselife is dramatically shortened and I would be needing a hammer to open the bolt if I went any faster.
Have you verified this with a chronograph? Do you have any idea of the pressures involved to get there?

Im 15 years old, just got my first deer rifle... a Savage m16 .270wsm. it has a 24'' barrel and is stailess steel, with a synthietic stock. it kicks really hard but i think thats because its such a light rifle. but i just love the groups i get and the handiness the caliber has in georgia woods on whitetales. might even take it a a black bear hunt using 150 grainers. i shoot federal premium nosler accubond 140 grain bullets (yes i know its factory i dont reload ..yet). i suggest a .270wsm to anyone who needs a medium sized game rifle. oh and my whole setup costed me bout $600 so a Savage is a good rifle for the money challenged hunter.
