Apologies. I made contact with Alliant and since I was currently working with my 223/556 16" AR AND because the guy I talked to doesn't believe in QL, we used existing load data from their files. That and I wanted to see if the issue followed to a different cartridge and it sure seems to have.
I'm new to QL but have a pretty solid grasp. It has been remarkably close at predicting loads for LVR, 8208, etc but way off on Comp. I can't blame QL though as the numbers are just plain low compared to another contacts results.
I did a ladder with my 22" Cobalt Kinetics gas gun using Comp and 103 ELDX. The numbers show QL predictions first vs observed at top and bottom
23.8 2540 predicted vs 2120 observed
24 2557
24.2 2574
24.4 2591
24.6 2608
24.8 2625 QL says 53k 2286 observed
25 2642
25.2 2659 vs 2294fps observed
25.4 2676
25.6 2692 predicted vs 2320fps observed
Same gun, same 103ELDX with LVR including sd numbers Actual numbers first
LVR ladder CK
27.4 2560 6.5sd 2 shots only
27.6 2598 5.8sd
27.8 2595 8.9sd
28 2609 11sd
28.2 2636 12.1sd
28.4 2643 9.9sd
28.6 2682 14.9sd
28.8 2695 19.4sd
29 2698 3sd 53k psi estimate 2 shots only
29.2 2728 15sd QL estimates 2707 22"
I guess I could run the Comp ladder higher in charge, but 300-400fps is a lot to try to gain. So I guess what I'm wondering is has anybody here used comp to push teh 103 ELDX to reasonable speeds? 2300 from a 22" is just plain sad.
Since I am in 223 I've been looking at running a quick test of AR Comp vs RL15 and possibly TAC at same load just to see how they match QL predictions. 25.6 Comp is pretty crunchy and TAC appears to be less energy, but we'll see if they match QL. My main purpose is to identify if I have a bad lot or just a bad bottle of Comp or???
