If it is a .22-250 and a 110, your talking an older gun or re-barreled. Did it also say "series J" on it? Oddball screw spacing with limited stock replacement options if you ever wanted to.
If it happened to be one of the odd cast receivers with the scope bases as part of the casting, pass on it.
not worth $400- unless you want it bad or some one can prove it was shot very little.
