Okay boys, I just picked up an old 602 Brno to build a new heavy on and I'm looking for ideas for caliber. This will be a conventional heavy with custom wood stock, barrel band front sight, quarter rib with 3 leaf rear sight, short forearm with ebony tip and barrel band sling eye. DO NOT want any of the following 'cause I've either got or have had.........416 Taylor, Rem, Ruger or Rigby....458 Win, Lott or Ackley........anything in .470 have a double in .470 NE. Must be over .40 and up to .50 and no I don't want a Gibbs. Will consider any wildcat for which brass is available for and want to shoot heavy for caliber bullets ie 450 gn 416 or 423..........550 in 458......would consider .475 if bullets in 550-600 gn available, or any other odd SOB you can think of. Want to stay away from big Wby cases and bigger, must be able to get 4 under.
Cost not a factor will design and buy reamer if you come up with cool wildcat.
Let's hear your wildest fantasies of your dream heavy caliber.

Will do metal work myself and will contract out stock work, will include photos of build after cal has been selected, this should be cool !!!
 
Way out of my league here, and have never/will never hunt dangerous game, but having one .404 'wildcat' here already, I would like to shoot a .425 Express or the Dakota wildcat version of this cartridge, the .423 Dakota. Anyway, following along here for interest.

Does the big Brno action have a drop magazine? Been a while since I handled one.
Big enough action that most anything reasonable is going to fit.
 
The .500 Jeffery is cool, but wil probably require some skill to make it feed as it should. Same goes for the .425 Westley-Richards.

It will mean finding a skilled gunsmith, and paying a bit more - but the cool factor and exclusivity will be there.

:( :( OUCH that hurt !! I've been amature gunsmithing for 35 years and have tweeked and stoned many a difficult cartridge/action combo into feeding like a 300 H+H.

Just did a bunch nof reading and I see what you're saying, forgot the Jeffrey had the heavily rebated rim and I see the attendant feeding issues. May well be beyond my talents as you indicated.

404 Jeffery would be my first candidate. Then maybe a 500 Jeffery or 450 Rigby. The 425 Westley Richards would be an outside dark horse for me as well, but the 404 Jeffrey would be my first pick, given the criteria. If you want something really different you could go with a 465 H&H. Obviously they must have a source of brass to offer it in their new rifles so you could get something as interesting than an obscure wildcat with the benefit of having reliable components and data.

505 Gibbs would be my first pick overall if I had the same action sitting in my safe waiting for a new job.

Why would you go with the .505 Gibbs over the Jeffery in that action?

Nothing overly logical, I'm just a Gibbs fan. There's something that I just don't like about the rebated rim on the 500 Jeffery, even though it doesn't offend me on the 404. Unfortunately the barrel blank I have is .510", not .505" so I'm not exactly storming ahead on the project.

The .500 AHR takes care of the rebated rim issue - although it is not a "classic". Of course the .500 A-Square takes care of the rebated rim issue and the brass availability/cost issue as well, but it has a belt (not that it bothers me).
