Starting to load some 22-250 rounds for a buddy tonight and was surprised at what QuickLOAD returned. Using H380 powder with Sierra 52Gr. HPBT MK #1410 bullets. Started with Hodgdon web site and plugged in my powder and bullet. Hodgdon web site shows starting load at 38.0Gr. Vel=3509, Max load 41.0Gr. Vel=3717 using 52Gr. A-MAX but does not provide barrel length. Sierra manual shows 38.0Gr. Vel=3500 and Max load 39.2Gr. Vel=3600 with a 26" barrel. Since both show 38.0Gr. at 3500fps I set my QL barrel length at 26" to compare the data. I have loaded 38.6Gr. in the past with an average Vel of 3594 out of a 24" barrel
Here is the problem. If I plug in 38.0Gr into QL, I get a Vel of 3779 and 39.2Gr. a Vel of 3900fps; both of these are about 300fps higher then Hodgdon or Sierra show with the same powder charge. Now if I plug in the 41.0Gr. that Hodgdon shows as Max, I get a Vel of 4080 and WAY over maximum pressure. I would not think that Hodgdon would show a load that would be this high even with all the disclaimers. This make me think the data I am getting from QuickLOAD is incorrect. ???
I have included a screen shot of the 41.0Gr. Please let me know if you see anything I am doing incorrectly here to show this data.
Thanks!
