I have a BAT HR on a 13.5lb 7 mag LR rifle, and a Stiller Predator on a light weight .270 WSM. Each action seems well proportioned for the rifle built on it. I have not used a Defiance... yet, but they do have a great reputation.
When I was researching the LR rifle, the 'smith I selected opined that he felt the BAT was the best action available, so I went with it.
Bottom line is, I don't think you can go wrong with any of the 3 mentioned.
Wow, old thread. Any pics of the rifle?
wow I didn't realize that til you posted it.
he probably scrapped the idea of all those cheap actions and did a savage!
