This is an A-II action rifle that is 37 1/2 inches from the butt to the muzzle. The barrel measures 17 1/2 inches from the front of the action to the muzzle. I am not aware that Sako made any rifles with barrels that short. Including the chamber, the barrel is likely to be 18 1/2 inches. The stock is obviously custom and not factory. It is chambered in 7mm-08. The story told to me by the seller is that he wanted his wife to go on a safari with him, so he had the rifle made up for her. The LOP is 13 1/2 inches and the cartridge it is chambered for are reasonable for that purpose. He says when she got to Africa, she shot one zebra and then refused to leave camp complaining that it was hot, dusty, the safari vehicle was rough riding, and she wanted to go home. When the guy returned home, he put her rifle up for sale because she said she would never go hunting again. It's a good story, but I don't know if any of it is true. Maybe some of you boys can tell me what I have here. Whatever it is, it sure shoots REALLY GOOD!!! I have shot five different reloads in it using 140, and 160 grain Nosler and 120 grain Barnes bullets with IMR-4350 and H-380 powders and every one was an inch or less, one was 1/2 and one was 3/8 inch @ 100 yards. It's a keeper, but what the heck is it? It all looks custom to me. Maybe the story I was told is true?? What do yawl think?
