Culpeper/Pstein:  I really appreciate your help.  I'm familiar with the Thurmont range, going there with the Maryland Schutzverein a few times a year.  The Caroll County range is new to me and I shall follow up. 

In return, may I alert you all to something called the Victorian Rifles Association. It encompasses all British service firearms issued during the reign of Victoria.  So we go from flintlocks (75 cal)  to Mk I Lee-Enfields (303).  It meets in the Fall of each year at a range in the vicinity of Easton, Pa. for 2 days.  A lot of Martini-Henry's, Sniders, Lee-Enfields at 100 -200 yards.  There are several categories of completions and medals awarded.  Everyone is welcome.  Folks from GB, South Africa, Canada, U.S., Australia and fellow-travelers from Europe attend. A pig-roast has become a tradition.  Authors on military history offer evening discussions. 

Thanks again.  Annapolis
