[QUOTE="Pdvdh, post: 207535, member: 4191"] [b]300 WM, 210 Berger, Retumbo[/b] I just loaded and fired some Retumbo today in my 25.5" Lilja barreled 300 WM. These three loads were a followup to a ladder test I shot last weekend. Lapua brass; CCI 250 primers; Bullets seated 0.007" into the lands; Chronographs 10-15 feet from muzzle; 79.0 gr Retumbo - 4 shots averaged 2899 fps ES=13 SD=7 4 shots - 1 3/8" @300 yd 79.5 gr Retumbo - 3 shots averaged 2936 fps ES=31 SD=16 3 shots - 1 1/8" @300 yd 80.0 gr Retumbo - 3 shots averaged 2950 fps ES=35 SD=18 3 shots - 1 5/8" @300 yd Other than the ladder test and these groups, I've never used Retumbo in the 300 WM before. I'm going to try 79.2 or 79.3 gr and shoot at 600 yds next time out. Retumbo is providing me about 75 fps more peak MV than H1000. But I think H1000 may shoot a little better with this Berger 210 in my rifle... Still a work in progress. [/QUOTE]
