I have this exact rifle, Sako heavy barrell single shot 22PPC and it has been the most accurate out of the box rifle I have ever had . My son just shot a five shot group under .250. ( 25.5 grains of AA 2015 Fed 205 match primer Berger 52 grain bullet ) When I shoot it groups range between .250 and .5 an even the factory ammo I had when this gun was new would group under .4 This gun shot like this from day one and the only change I made is to have it glass beded when it was about five years old. I do not know if they still make this model but I just saw a beautifull Sako 22PPC Varmint Model with laminated stock and heavy stainless barrell in the Powder Keg gun shop in Kamloops B.C. Canada. took all my will power to not buy it. By the way my 22PPC must have over 1500 rounds through it and is still great. Check Sako's web site, but i Think all thier rifles are box magazine repeaters at this time.
