The reason I ask is because I just bought on for a 6.5x55 sporter conversion project. It is in 8x57. It must have been rebarreled somewhere along the way. It really doesn't matter as the action is going to be rebarreled to 6.5x55 anyway. I was just curious if it was original or not. From what I can find, the 1909 Argentine action has been highly sought after for custom conversions. So I guess I got a good one for my project. This gun was already carrying a sporter stock, was D&T for a scope, had the bolt handle altered for a scope and had a low scope safety. It also has a nice aftermarket trigger guard. So, all the work has been done. All my 'smith has to do is install a new barrel. All this for $265. I couldn't pass it up.
