[QUOTE="CogburnR, post: 1307112, member: 29174"] If you are using these loads for Elk hunting then loading them for reliability is important. I would load them at the recommended coal. Often cartridges loaded "at mag length" can easily hang up at a bad time. Always allow for a decent amount of clearance for reliable feeding under hunting conditions. I looked at Noslers Data and while they do not list H4831 they do list IMR4831. You can use that data by reducing it 5% for manufacturer differences in this powder, then reduce that charge by 5% for starting loads. In my experience many times the powder from these two manufacturers is within 3% of charge weight at max charges. IMR4831 is definitely a faster burning powder though-they are not exactly the same(you may find the H4831 may need a couple grains more powder for max than the IMR). When working up loads remember that a "max load" may not be best for hunting. A load reduced at a minimum of 2% from the working max should be considered a hunting max. Conditions such as the box of cartridges or the rifle warming can create problems. Of course H4831 is pretty stable but a max load that was developed on a 50 degree day could be a little hot when the rifle or cartridges are 100 degrees. Often times accuracy may be quite different over the charge range and the more accurate load should be favored unless it is at absolute max. A couple grains of powder less can make a difference in feeding and accuracy but not much in yardage. [/QUOTE]
