Buddy just built a 6.5-06 with a 24" tube. Hes using the 147 eldm with an OAL of 3.375" Can we get all powders at max pressure please? Hes using Retumbo right now and its waaaay to slow for him. Lots of carbon and unburnt powder he says. Thanks for the help!

I'd forget Retumbo or H1000 unless I had a much longer barrel. 8)
