I thought you might be a little closer. The only Whetstone area I was aware of is West of Mountain Grove. Whetstone Creek
The 617 will let you get in lots of quality trigger time without a huge expense in Time or Money.
I shoot a lot more 22 LR through my Contender than I shoot centerfire through all of my barrels combined. It is just plain fun to shoot, and does not require a large expenditure in time reloading to shoot a few hundred rounds.
See You At The Range
