So here's what it looks like.
Savage 16FHSS is chambered in 250 Sav, 7 lbs, about 7-750. More expensive and heavier with the AccuStock.
16FSS or 11 FNS can be barreled in 250 Sav at 20" for an upcharge of about 80, 6.25 lbs, up to 6 wks. delivery time.
Looks like a used M77 ultralight is going to be up to a few hundred more.
I have a line on a little used 1952 Sav. 99. I'll probably still go with a bolt gun though.
