I owned one and sold it.

Well, first off it is definitely not a Mauser.

Next, "bargain" is a very misleading term. Yes, the purchase price is cheap-but not nearly as cheap (not "inexpensive") as the quality of the action. It can be turned into a decent action, but if you do not do it yourself and consider your labor free, then it will wind up costing more than a Granite Mountain Magnum Mauser.And even after you spend more than a granite action costs, it still will be lower quality than the GMA.

There is no need to start making them because they are just the CZ Magnum action. The only meaningful differences are the BBK bolt is larger than the CZ (.730" vs. .700") and the threads are British Imperial vs. SI. I have had people tell me I did not know what I was talking about here many times, and for that reason I took pics of the the BBK next to the CZ 550 Magnum from several different angles. The series of pics clearly show the actions on my bench are the same. Well not the same because the "rough" CZ is 1000 times better finished than the BBK. I looked just now but did not find the pics on my hard drive.

Yes, they were sought after before CZ started making their actions. That scenario has changed.

It all depends on what level of quality you need to make you happy. You can't build a top level rifle with one of these actions, but then most people want a lower quality product anyway. With a good bit of work

THey are gone and I say good riddance. THe only redeaming quality they had was the larger diameter bolt for rounds such as the .505 Gibbs and related wildcats. For anything other than a .505, use a CZ.
