Been awhile since I had that rifle but I believe they chronoed at 3250. Not as fast as I could have gotten them but very very accurate. I do remember my groups could be covered with a nickel. 3 shot groups.
That was my expirence. I have loaded retumbo for about last 1.5 yrs. very pleased with its performance. Found better accuracy & velocity than other powders tried. Getting 1/2 MOA 2.87" at 600 yds with Berger 210s at 3100 FPS.Most people try different powders, and end up shooting Retumbo in a RUM.
Not that I know of but you can email Alliwynn directly at the site and he'll either direct you to the appropriate page or just answer you directly.I seem to be having a time negotiating that website, is there another place to get more info on their bullets?
