Back in the 60's and 70's Les Bauska of Kalispel Montana was having oversized Ruger #1 Actions cast and was making .577 and .600 nitro rifles with them. When I was in his shop in 1975, I kinda recall seeing an as-cast action, but can't be sure. Might only have been a picture. There were no finished rifles in his shop.
Does anyone here know anyone who has one?
