I think this is a great move by Ruger, for various reasons.

The chief benefit I hope to see is FACTORY 450/400 ammo with Woodleigh bullets as well as others, Swift A Frames etc!!

Now I can play with a 450/400 single shot till I can get the 450/400 DR want!!

Eventually I hope this will affect current DR makers to maunfactor more 450/400 Doubles.

Time will tell. I like Rugers decision.
