Once one of more of these showed up I backed off to the last most accurate charge. About 10 years ago I finally pick up a chronograph but never really got around to testing the swede. A few weeks ago I ran 10 rds thru it and discovered to my astonishment it was shooting 140gr spbt at 3008 fps average with a SD of 10 fps. All the literature I've read and research on line indicates the 6.5x55 shouldn't be able to handle this velocity without extreme pressures and probable damage to the firearm and or myself. My question is do I continue with this load or abandon it as a ticking time bomb?
With a variety of powders, Quickload thinks you must be around 80,000 psi
to reach that velocity with a 140 gr bullet... tick, tick..
