I have a BRNO 602 .375HH made in 1967. I am now thinking about converting it into a .416 Rigby.
Does this requier new triggerguard/floorplate? new magazine box? extensive action work? Are the nessesary parts readily avalable or are custom made (ie expensive) gun parts called for? Is this a job for an average simth or should only the elite be considered?
This will be my DG gun for Africa/Alaska. 100% reliability is a must.

Carl,

I would sell your BRNO and then buy a CZ in .416 Rigby. If your BRNO has the pop-up peep sight you will certainly be money ahead.

If not, you will save a lot of time and effort.

I sold mine, it was also a .375 H&H.

Carl,
were it me, I would sell the 602, buy a CZ or ruger in 416, and spend a couple bucks going through them..


If you are deadset on the 602, the "correct" choice is 416 remington, as the feeding/modifications/frustrations will be FAR FAR FAR less than getting the rigby to feed...

and you probably can hold another round down in rem vs rigby.

If you are determined to proceed with the rigby, you'll need

cz 550 mag box
cz 550 rigby extractor
weisner's 550 floor plate
cz 550 rigby take off barrel (please start here)

You smith will need to
open the boltface
install, time, headspace the barrel (sights will be there)
install the extractor
perform "normal" feeding work
install the floorplate (should let you get an extra round down)

This does NOTHING for the poor trigger/safety, but if you like them, you should be fine

reblue the whole thing

Cost-wise. less than $200 in parts, probably 400-500 in total gunsmithing

Keep your 375, fine rifle and go buy a 416, you will come out about the same in the end.

thanks, Billy
