Sorry....brain ASSUMED 458 WIN MAG......ended up clicking on the website......lots of claims but I wanna see it to believe it.......welllllllll.....maybe not in person but behind a concrete bunker.......300gr of really fast powder behind a 300gr barrel plug.....NO THANKS!!!!
I don't have the issue, my buddy that has the 40x action does, but he was telling me that in the May issue of American Hunter there is a acticle that Randy Johnson(Owner) shot 300 grains out of his gun, which is a Howe. I will never try 300 grains, tried 250, will stick with 200. I am very impressed with this gun. I don't have the bedding block in mine but plan on bedding it this weekend. Waiting on my Farrell 10moa bases.
