Walking out on a limb here.
I am starting load development for a Ruger Hawkeye in 6.5PRC with a 26"pipe. I have bullets selected 140gr sierra matchking and berger140gr VLD target. Would like to shoot targets out to 1500yds one day.
I am trying to choose a powder, I have on hand Retumbo, US869 and H1000. I also have this 8lb jug of H50BMG thats been bugging me for about 10 years since I bought the Barrett 50 but have not opened the jug.
The 6.5PRC being a new, there is not much data out there. The Hodgdon annual manual shows the use of Retumbo, H1000 and US869 with 869 producing the highest velocities but with some of the lowest pressures. The burn rate chart shows 869 being the slowest and is one step slower than H50BMG. The other powders I listed above are all faster than 869 and H50.
My other option is IMR 8133 which there is data for and is temp stable and has CFE. But I have none!
Would YOU as an experienced handloader try or have tried a powder not listed in any manual? And if so where would You start?
Am I out of my mind?
