What affects accuracy more, bullet weight or sectional density?

Had my best luck on my 300 WM with the 180 SGK's and H1000. 7828, RL 22, 26 and Retumbo I had no luck with. Each rifle will be different though. Give those SGK's a run with the H1000, you just may be pleased.

H1000 seems to be one of the more common recommendations, tho not one ive tried. Maybe next time that .300 comes back for more ammo ill get some and try work up a new load with it.
