I shoot a custom made 300RUM long range rifle. I have tried H-1000, Mag-Pro, Retumbo and Magnum powders to find which one shoots the smallest MOA. Retumbo won the contest hands down. My longest 5 shot group was shot at 1234 yards and was 4.39 inches. My best 5 shot group at 100 yards was .247MOA with a 200 gr. Accubond. Now that's performance!
i loaded 10 with the hodgdon 1000 and 10 with retumbo on my 7mm rem. at 100 yds the h 1000 had a 4 inch circle. and the retumbo had a 2 inch circle. i could not believe the difference in just changing the powder. its retumbo for my hunting trip to idaho!
