[QUOTE="frostop, post: 1613064, member: 22611"] Is there a direct correlation to how well a given powder will work in a given length barrel? The reason I ask is I have been working on a load for a 270wsm 26" barrel, initially i have been using Retumbo, I have been getting good groups at 100yds but lousy SD's. Then yesterday I loaded up some H1000 and I really didn't even pay attention to the group size but got a single digit sd? So I have to wonder if Retumbo would really like a longer barrel to burn the powder to a more stabilized point? Gary [/QUOTE]
