Got that covered Jim, thanks. Been away for a spell, sorry for the slow response.
Also am a bit pleased to announce the .22 GTC has been blooded. The surviving squirrels are having a protest as I type. From all appearances the cartridge has a propensity to over-penetrate. While the bullets were subsonic and not hollow pointed I note that placement within a half inch or so of the ear pretty much carries the day. Every time. High shoulder shots work also.

PS: Some time ago it was suggested by a rep. from Hornady that I submit a proposal for production of this marvelous thing and pass along that it was forwarded last week. All 5 pages or so. Will pass along any feedback that results.
