I like the 25 WSSM and currently have 16 Winchester/USRA 70 chambered for it.

Here is the distillation of my experience with the 25 WSSM since 10/04:

1. It is hard to find anybody who owns a 25 WSSM who doesn't have good things to say about it.
2. It is hard to find anybody who hasn't owned a 25 WSSM who doesn't have bad things to say about it.
3. The 25 WSSM is, performance wise, the same as a 257AI. A little faster than a 257 Roberts or 250AI and a little slower than a 25-06 or 25-284.
4. Winchester/Olin WSSM brass is very thick/heavy. Most of the 25 WSSM ammo that I shoot is made with resized Federal 223 or 243 WSSM brass.
5. None of the Browning or Winchester/USRA 25 WSSMs had chrome lined barrels.
6. The WSSM guys hang out at www.wssmzone.com, so you might get more input over there.
7. If you want to dialog about the 25 WSSM, feel free to PM me with you questions.
