Guys, thanks. A good start for me to review. I tried the 2400 load because the Lyman 50th velocity was 1,001 fps and I understand that cast bullets may be too soft to exceed 1000 fps. I bought these Remington 240gr at a shot show probably 30 years ago and I just got interested in trying them out and found they are very accurate.
My Ruger is a 7.5 inch barrel. The starting load velocities and CUP pressures from Lyman 50th are Blue Dot 933/34,500.....H110 1204/31,800......IMR4227 1036/29,000...
A#9 1009/25,700...compared to A2400 1101/34,700.
I have used H110 for 40 years with JHP bullets, but I don't want to go that fast with these cast bullets. Accurate #9 looks really good due to lower pressure and IMR4227 is a good second. Blue Dot is the lower pressure but 933 fps, which is nothing to sneer about, although to see how these various loads compare I'll have to buy IMR4227 and A#9.
This makes me wonder how I picked 2400 with more pressure than H110....probably because I had it since I first started reloading and it was suggested to me by an older reloading relative at the time -for JHPs. If you were me, where would any of you start at this point? I'm not indecisive, just interested in opinions.
