[QUOTE="Mysticplayer, post: 3034, member: 8947"] [b]Re: Med-Long Range Load Development How-To\'s[/b] You can try and back up your group size with chronograph data. Small groups and small variations in vel indicate an excellent long range load. That is how I do my load development too. However, I will always shoot at long range to verify because short range shooting can not show you any stringing that may be occuring. This stringing can make your groups huge at long range. Also temp. variations can affect your long range performance. I am now using Hodgdon Extreme powders for my hunting loads because of their stability during temp. changes. They usually burn very well too. H4350 and H4831SC are what I use now. For my 300RUM, I will be using H870 to start. This is supposed to not be temp. sensitive. However, I have never found a ball powder that wasn't. WCC 872 is also a great surplus powder. If you are building your loads in the cooler months, back off when shooting in the summer. Good luck..
