I used to collect Browning .22 ammo.. As I recall Browning had it's name on seven different types of .22 ammo. eg; shorts, low-velocity LR's, magnum's, etc.. some were 50 per box and others were 100 box.. some were plastic boxes while others were paper.. I suggest you check to see if he has any of the other types. I'd like to have any shorts, magnums or the paper box of 50 in Standard velocity. The 70's is about right for that stuff..
Browning .22 ammo is still very desireable.. The type you show in the pic is probably worth $25 ..but I can't say for sure, as it's been a number of years since I've collected Browning ammo. It's difficult to find ..
With 2 days left he doesn't have any bids either. They may sell for what he is asking but I think $25-$30 is closer to the real value. I wouldn't shoot it, but save it for collectors. It isn't going to shoot any better that CCI SV or other equivalent ammo. They don't make it any more so don't waste it.
It's collector stuff,so naturally the condition of the box and label is important to value.I agree with the above stated values.I used to have some myself,but realized that the value was really just in the label ,the ammo itself isn't anything that special-""B" headstamp? so what...and was made for Browning by CCI or somebody....The label wasn't worth $20 to me,and that's generally how much more it sells for over comparable ammo.
