[QUOTE="just_jon, post: 2722153, member: 112153"] All my 45 year of reloading experience got me was a bunch of wasted components by using conventional powders with the HH or AH. It was difficult to put everything I had leaned and think outside the box. Fact is H4350 is just too slow burning for the 123AH. By that I mean you will reach 100% case fill long before reaching pressure and an acceptable speed. Because the AH data in QL is reported to be unreliable, I ran the data for the 124 HH. At 100% case fill, you get 48000 psi and 2719 fps from a 24" barrel. Look for a powder that gives you 90-95 fill rate at max charge weight and work up toward that charge. Recommend something in the Varget, Hodgdon BL-C(2), IMR 8208 XBR or IMR 4166 burn rate range. [/QUOTE]
