[QUOTE="Cold Trigger Finger, post: 961795, member: 56732"] But even with the 26" barrel I could have got more velocity with the 275 grain bullets that I shot in it. And the 300 gr bullets would have been benefited from more powder capacity . . I also found that it wouldn't have been too hard to get the 550 CZ action to feed it and the Edge. The factory 250 gr Swift A Frame load chronographed 2950 fps with less than 25 fps variation. I got the 275 s up to 2900 fps with H1000 or 7828 . I wanted to try Retumbo but sold it before I got some. If I was going to build a mile shooter I would start with a Richardson+Roberts action and have Matt build a 338 Edge probably with a 28" barrel with one of those jet engine brakes on it. Have Matt mill as much moa into the square bridges as he could and make them Picatinny bases. [/QUOTE]
