Unfortunately, expect to pay a premium for one. Not gonna find one for $600-$900, like the 99’s in 250/300/303 Savage. Probably 1 Model 99 in 358Win for every 100+ of those others. They are rare.
Thanks for the lead. I somehow missed that one in my search. I already found him a near perfect 300. But he really wants a 358. I know I’ll have to pay a premium price and that’s ok. He’s worth it.
