71.5 grains of H4831 works very well in my Ruger No. 1B with 140-grain buillets. MV 3350 FPS, 1/2 MOA accuracy.
I talked to you a while back about this load and decided to give H4831 a go. My 700 lovesit but hits it's limit @ 69grs for 3200fps. H1000 and Retumbo give me just over 3300. Just goes to show every tube is different.
