When you find .348 WIN let me know - I need to feed a Model 17.
I think Buffalo Bore has it at $90 for a box of 20. But there is free shipping.
A reloading outfit would pay for itself very quickly at those prices.
Even the simplest, cheapest reloader could reload a box in half an hour.
I did that with a .300 Savage and an old Lyman 310 tong tool when I was 14.
