Hi all,
I have a number of Savage bolt rifles 112, 12...all BVSS, various calibers. I've been using them a long time and shoot often. I finally broke one! The extractor chipped on the model 12 .223. When I took it apart I lost the ball (of course). I had .125 chromed balls in my toolbox. I got the new extractor form Midway. The new extractor is not identical to the old one. The old one was longer, engages the groove more. This is the same on all of my rifles. The new one works fine though. I read this post a while ago and also ordered 9/64" balls from McMaster Carr. I put the bigger ball in and it just made everything feel better (like new). I think I'm going to do springs, balls and extractors for the whole lot before spring happens here.

Thanks to all who contribute.
