Interesting thought. I have never used LT30 in my 22 Hornet, but 1680 is THE powder for accuracy in my rifle (a Ruger #1 with some tuning). It gives up ~200 fps velocity with a 40gr V-Max compared to Lil'Gun or H110, but no other powder comes close to shooting as well in that rifle as a nearly-full case of 1680. Something about that combo ended up being magic, while most everything else was just "blah".
