I have two questions: I'm loading 168 grain Hornady Amax bullets in .300 win mag. According to old data I have the max load for IMR 4831 is 72 grains, IMR 7828 is 76.8. However, using the online Hodgdon/IMR website, it lists a max load of 75.5 for the IMR4831 and 80 for IMR7828- this is for the 168 grain BTHP. What gives?
2nd question I did test loads using aforementioned bullet and RL22 worked best. I then reloaded ten rounds with RL22 at 79.1 (max load). Five rounds were in new Remington brass (resized, trimmed to identical length) and five rounds were once fired federal brass sized to exact same length. The group with the Remington was not as tight as the Federal-- do you suspect this is due to position I was firing from (prone for Remington, bench for Federal) or likely from the brass itself?
I shifted positions as when I got to the range the prone bench was the only one open, later, the regular bench opened and I switched to it......
Any other recommendations for loads of 168 grain Amax in .300 win mag?
