I have a Tikka T3x/T3 3 (S5850371) round mag for wsm's and 1 x-bolt (112044603) 3 round mag for wsm's also that are new and never been used. Bought them for the followers and found out it's not going to work for my intended purpose. BTW, I don't own either of the makes of firearms for these mags. Not sure what shipping cost will be?
