[QUOTE="West Calamus, post: 2242529, member: 110228"] Start your jump .020 off lands and go in increments of .020 to .080, ogive off lands. Take your best group and fine tune from there. I only use 175 and 200 grain bullets in a 1-10 twist 300 WM so can not help you on powder. You should do your powder test with different powders and ladder test your charge weights for best group before you do your jump to the rifling. I take it you live some where other then North America so I would test powders that are available to you . Nothing the matter with Vihtavuori powders... [/QUOTE]
