I've have a '94 Brazilian in 250Ackley w/everything you can do to one. COO, 2 position Win safety, Timney, and FN bolt. I also have my Dad's '95 in 7x57 that is sporterized but no COO. They both work great and have been excellent hunting rifles. I've also built a 338Federal and 338-284 on the small thread Turk actions. Both were good shooters. The Turks are real sleepers...especially if you want to re-thread a bastard barrel to one of them. powdr
