500grains, I just got a E-mail from a personal friend , and a person who knows as much, or more, about the currently made double rifles as anyone I know! He agrees with your take on this subject, and says he has personally disassembled the new Rigby, and they are definently Merkel actions! I will not post his name here but everyone who has anything to do with double rifles knows him, or of him! I will send the name to you in an E-mail if you want!

Haveing said all that, I will concede to that informed opinion, as to the origin of the action on the new CA Rigbys. I will say, I do not like the new Rigbys, but that is a personal opinion on my part, and makes no difference, since I can't afford one of them, even if I did like them. However, I fail to see what difference it makes who made the action, as long as it is strong enough for the job! As far as I'm concerened, the action, in this case, is the best part of the rifle! Again, that is only my opinion, and worth only as much as you pay for it!
