I've always used rl22 for my 300 wby with a 180gr partition. However, after I got a chronograph I've seen some bad velocity variations with my loads. One range session yielded velocities from 2950 to 3140. This rifle has always been somewhat inconsistent, and now I see why. I've seen on here that others have had similar results using rl22 in the 300 wby. Some say it's temperature, some say it's due to the powder having a narrow sweet spot, and some say that one is the result of the other. I'll be honest, I only started using rl22 because it yielded the highest velocities in the reloading manuals. As I've matured as a shooter and re-loader I see the error of my previous thinking. From my research I see that some people swear by IMR 4831 and others swear by H4831. Is there really that much difference? I'm just looking for an accurate clean burning load somewhere between 3100 and 3200 fps. What do you guys think?
P. S. I can't believe I ever did any re-loading or muzzle loader shooting without a chronograph. I never go to the range without one now. If you're reading this, and you are trying to re-load without a chrono'. Do yourself a huge favor, and get a chronograph. Re-loading without one is like shooting with your eyes closed...
