Chopped a 1906 Gustaf Swede down to a 24" barrel, beavered out a new stock, installed a Dayton Triaster trigger, put on a butter knife bolt handle, and its 117 year old tube consistently deals out 1/2 moa accuracy with 140 grain Noslers. Was originally purchased as a truck gun, but it lives in the safe beside Weatherby's, Remingtons, Winchesters, Rugers, and a Sharps. One of the cheapest but most accurate units in there. Those folks seriously knew how to manufacture a rifle.
For initial tests, I assembled a ladder load series ahead of IMR4350, and every slug tucked into an area that could obscured by a quarter. Will have to stretch it out a few hundred yards to maybe get a valid assessment.
Your cut down Swede sounds cool. I damn near bought a Kimber of Oregon sporter model made from a Carl Gustaf m96. I figured there would be a good chance it would digest the ammo I load for my all original Swede/Carl Gustaf m96. It's tempting, but he wants too much for the rifle. He's wrongly thinking it has a lot of value because it has Kimber written on it. I'd rather have a Tikka and take full advantage of the potential of the 6.5x55 cartridge, but then that ammo probably wouldn't be safe in my old military rifle... Kind of a catch22...
