CrowRifle,
That's good news on the 450 with Lil Gun. The Hornet is perhaps the most primer sensitive rifle round I've ever used, and while pistol primers work great with some powders, they don't work so well with others.
I generally use sCCI 500 small pistol primers when loading H110/W296, which works a little better than Lil Gun in my experience with bullets lighter than 35 grains.
Lately Lil Gun has been scarce, and I tried Alliant Power Pistol 300 MP because their data also showed good results in the Hornet. It's a little slower than my present lot of Lil Gun, but not much, requiring about about a half-grain more powder to reach the same velocities. Accuracy is very good as well, especially with the CCI 450 small rifle magnum primer.
