LAST EDITED ON Mar-09-09 AT 10:53PM (MST)[p]I have been using Barnes TSX bullets in my 300 WM and 264 the past year and a half or so and the bullets work well with both rifles.
I took a small bull elk last year right at 100yds with the bullet entering just behind left front leg then took out a bunch of stuff while working its way through the right front shoulder bone where the hide stopped it. Bullet performed as advertised and bull dropped where he was. Did not clean the bullet, but it weighed just over 180gr in my scale when I returned home. Switched to the Tipped TSX's now to try and gain a bit more accuracy at further distances, but expect the performance will be the same.
Due to the lack of weight loss as the bullet does its job, its been said that you can use a bit lighter bullet than you usually do and achieve the same performance. If you are used to using 180's then you could step down to a 165, but I like the 180's so I'll stick with them.
