Thanks for that very informative post 44forever.

OFT, I've had the same thought about shooting many 300 grain magnum loads in the NG 329. I asked my local gunsmith about it. Didn't seem to concern him, and S&W haven't come out with any caveats. I've been practicing with the 300 grain Hornadys since I read an article that rated that the best defense load for a .44 Magnum. I'll try to post the link if I can find it again.
