Cult you are correct the 400 speer Jacketed flat nose kills on both ends.
The 300 hp can and I have loaded to 55 gr rx7. My handi rifle shows no pressure signs with that load. But to make life simple I load both to the same 50 gr rx7 load. My speer #11 gives this load for the 400gr as 52 gr max. This is a level 2 load. My gun did not like 350 gr bullets. But these two shoot sub moa and hit like a freight train. Give rx7 and your 300's a try I think you will be surprised and happy. Good luck and good shooting.
