With 56.0 grains of 3031 behind a HDY 350JFP this this was shooting sub MOA at 50 yards with the skinner sights. Thanks to those who suggested the lee factory crimp die consistent starting pressures really helped tighted up the groups. Now if I can figure out how to get my file smaller I can show you folks the picture!

Should be a good load. I like 3031, but it was a tad slow for me with 55gr with 350gr horn flat nose. Only shooting like 1800fps. I was really able to kick it up with 4198.

yea I agree with you, it is a tad on the slow side. I am planning on buying some 4198 one of these days I think it has nicer performance for a wide range of temperatures as well. What loading were you using with 4198 and the 350 HDY??

Prarie_Boy1

and was it IMR 4198 or H4198??

I have been using IMR. No particular reason other than thats what I had.
