Be careful on starting loads. I got hangfires and high pressure with book starting loads and 8133 in my 28. As charges rose it behaved really well. I am going to try it in my RUM when I run out of Retumbo. I really like it.
For another example, I am loading 78 gr. 8133 behind a 180 Berger VLD in .300 PRC with no noticed pressure signs.
Here is a link to 8133 on Hornady website:
IMR Enduron 8133 is the slowest burn rate in the Enduron family. Loading density is perfect for magnums, contributing to superb uniformity. This is a true magnum propellant yielding outstanding performance in 6.5-300 Weatherby, 264 Win Mag, 28 Nosler and 300 Rem Ultra Mag, among other...shop.hodgdon.com
You can scroll down to where cartridge and bullet weight are selected - would not let me create a direct link.
For some reason, the site is kinda flaky from my phone and I could not choose just any particular bullet with that cartridge, but was able to find data for 180 & 220 gr. in 300 RUM here.
It's about mid-level by the book and shot good groups - old school here. If all goes well, a friend is going to provide a chrono and we'll get some ladders done for 8133 and RL26 tomorrow.that’d be seriously low power your 300 prc...I’m loading 79 compressed behind a 225 grain eld in my 300 win mag. Must be burning filthy!
It's not as bad as I thought it might be. But I do have a fairly heavy rifle and brake on it. Compared to a Benelli SBE with full bore 3 1/2" shells - it is gentle.Thanks for the great intel. How do you find the recoil on the 300 PRC?? I am considering a build for LRPS but do want a long barrel life and recoil that be managed over 30-50 rounds per day
