Primers can make a big difference in accuracy with certain powders in the Hornet. I can't remember velocity on my Lilgun load, but I do know I switched to Rem. 6-1/2 primers to get better accuracy.... just over 1/2" groups in a Ruger bolt. I think the Hornet can be a tricky bugger to load for but once you find the sweet spot in your gun, you'll know it. I also have a 22 hornet Contender that shoots absolutely great with 1680, but will shoot my Ruger load into 3".....same is true in reverse. I'm switching the Contender to K-Hornet so I haven't played with it much.
