Signs are .22rf. is getting short here in the U.K. I guess they are shipping out to the U.S. to satisfy demand there. We have our own domestic suppliers and also stuff coming from Europe. Shouldn't be a shortage really. My local gunshop is a bit short as supplies are not coming through. I have quite a bit on one side having just changed from an old BRNO rifle to a Sako Quad. The BRNO only liked high velocity and would not group with sub-sonic to save its life. The Sako has a sound moderator fitted and I want to use it with the quiet stuff. As a result I have surplus HV stuff; about 750 Winchester Rabbit Ammo (Australian made) 300 Federal and a few hundred rounds of Eley Tracer. Going in to swap it for 20 bore shotgun ammo. Lagopus.....
