Ive a new varmint SF in 223 that I ordered last month.
Its plenty accurate for me at 100yds with factory ammo.
Its got the 1/12 twist and loves the Fiocchi 50 and Hornady
55 grn Vmaxs.. Under .40" box stock before and after
I put a HS precision stock on it ( non bedded). They still
Make some good rifles but sorry to hear yours is not
Working out.
