Hornady flat-out says that 1680 is the hot ticket in the .17 Hornet, in their #9 manual, and they don't even have Lil Gun data there. There may be a good reason for that.

I had some ugly results with what should have been mild charges of Lil Gun in my .221 Fireball, getting pierced primers and sticky extraction in my little CZ 527. I now refuse to use the stuff. It works fine in my buddy's 700 Classic, but I don't trust it.
I've also seen a Savage M40 .22 Hornet locked up tighter than a tick, with another Lil Gun load, that should be mild enough, 12.0gr. Lil Gun with a 40 VMax. It locked that rifle UP. And folks say you can't put too much Lil Gun in a Hornet case...................................


You can roll a turd in peanuts, dip it in chocolate, and it still ain't no damn Baby Ruth.
