[QUOTE="Vol1975, post: 1649374, member: 100380"] Can be a lot of reasons but rl 17 in my opinion is a fast burning powder for a magnum. Case fill and how the powder lays in the brass will affect some, brass fill or same type of brass, condition of the powder, and neck tension. Every thing can add up to have a variance on constant speed. Personal I would choose a powder that would give u a more full case capacity. I run at least .002 of neck tension on my bullets and run a good brass that is the same in weight and maker. Also if you have shot the brass a lot I would consider annealing the brass. Again neck tension plays a role. Rl23 pretty good powder for that weight. H1000 has been good for me and many would say is a staple for the magnums. The burn rate around h1000 is where I would look. I have run h4831 with good success but had a lower ES with a slower burning powder than 4831sc. Anyway there is a lot of information out their on the 300win [/QUOTE]
