Thanks 280Rem, I believe you are 100% correct and definately have more experience than I do. I was thinking that since 139gr Hornady SPs are short, that I'd be able to get a satisfactory load with H4350. In reality I have. The goal was to use one powder (obviously H4350) in my 30-06/165gr. loads and 243/100gr. loads. I'm thinking I'll be good, at least for the time being. I might be going "slow" at 2900fps but them 1/2" groups are hard to walk away from! That's about as good as I can do with sporter 280 Rem and 6X scope. The best part is so far, it seems consistant. Thanks for the info.
