You say you have a Brno ZKK 602 in 300 Win. Mag, humm. I don't claim to be an expert in anything, but I have owned many, many bolt action rifles in just about evey make and several custom rifles. I only use Brno ZKK bolt rifles now and doubt that I will ever switch to another brand as I feel they are one of the best commercial rifles ever built for the money. They are not perfect in my opinion, but are as strong a foundation as one can buy. With a competent gunsmith and about $500.00 U.S. you can have a great custom rifle that will do anything a custom rifle costing $8000.00 or more will do.

I am only guessing, but I would say your rifle has already been rebarreled if it is a 602 action in 300 Win. Mag.. To my knowledge, all 300 Win Mags. were built on the 601 action. The 602 action was used for 375 H&H and larger calibers. Again, this is to my knowledge. I have never seen a 300 Win. Mag on a 602 action from the factory.

There is no reason why a compentent gunsnith couldn't convert your rifle over to a 416 Rigby. As far as what he will have to do to the rifle outside of rebarreling and sights I cannot say for sure due to the fact that I suspect the action has already been rebarreled as I mentined before. The 602 is a true magnum length action and will handle any of the magnum cartridges. Also, these actions and rifles are very well made and hell bent for stoutness. These actions are being used for farr larger calibers than the 416 Rigby, which is a low pressure cartridge anyway.

I am thinking about having one of my Brno ZKK 602 in 375 H&H rebarreled to 416 Rigby myself. IMO, the 416 Rigby is a great cartridge and the best of the 416 calibers. So go ahead and have it converted, I can see no reason why you would have any problems. Just make sure you use a compentent gunsith.
