What is the year of the earliest M99 chambered in .300? Also is it correct to think the 1899s never came in .300? I'm looking for two 99/1899s, one in .300 and one in 22HP. I think we all know which is going to be the easier one to find ( and cheaper ) :-D For the 22HP I'm looking for one with a perch belly so I know the date range and as long as it has a perch belly I'll go with any model. However, I'm wondering what the date range for the .300s are, so I can pick the model I want. I have a feeling I'll be able to be a little more picky buying on in .300.
