[QUOTE="speed, post: 731760, member: 45710"] Hallo One year ago I decided that I „needed“ a semi custom 338 norma rifle , after the decision was made to build it was time to begin research on reloading data with Vihtavuori powder for 250 gr bullets , after a lot of search on the internet with no results I decided that I would have to do it myself and start from scratch. I did use 338 lapua data as a reference point. The rifle is a blueprinted Remington 700 with 24” Lothar Walter barrel in 1-10 twist and custom muzzle brake and bedded in GRS varmint stock and topped with Zeiss 6-24x56 in Night force rings. Norma brass ,bullet is lapua scenar 250 gr ,primer is federal 215 m and col is 88,64mm(3,490” ), bullet seeding is everything , this cal is not picky on powder at least with vv . Vv 570 92=2880 fps 93=2930 94=3010 (stiff bolt ) I’m also testing vv560 and 225 Hornady sst and results will come later.
