I'm currently seeking someone who has a .22 WMR magazine for the P72 or P78 Sako rifles. There is a gentleman who has been reproducing the .22 LR magazines with great success and if he is able to either get his hands on a magazine or be given precise measurements over the phone and sent pictures, he may begin to reproduce them in .22 WMR as well. If anyone could be of assistance, you can get in contact with me and I'll provide you with his contact information. Who wouldn't want a source of extra magazines? His .22 LR mags run around $100 last I checked so the .22 WMR mags could be very reasonable as well.
