Necks are thin, be careful. I either use a Lee FCD or only resize about 1/2 of the neck with with normal FL dies. 13 gr of Lil Gun or about 10 gr of H110 usually seems to work well. Fitting that much Lil Gun in that tiny case can be challenging.

Almost all bullets for the Hornet are really fragile, are you going to teach him to ear shoot them?

Oh, and Gunner uses 45 gr TSX, claims it works great, it would surely hold together better than anything else I can think of.

Otherwise the various 40 gr plastic tipped bullets are best for varmints.
