Yes, that is correct.
Long range rifles use full power ammunition, you get 15 rounds, with 3 hits required on successive 100-200-300 yard targets each. The rifle should be the same era as your Skirmish gun, if not the same gun. In the expansion match, all guns are from the 1900-1916 time frame.
The Expansion era handgunner has an almost unlimited rifle selection, as long as he can reasonable justify its use with his persona. The 1911's natural rifle would be the 1903. But a battlefield pickup could be most any small ring mauser, or rolling block, both heavily used in the phillipines. Marines in China in 1900 picked up "Commission" 1888 rifles. An officer involved in the China Relief Expedition of 1900 (Boxer Rebellion) could possibly claim a rifle "acquired" from any of the nations involved! A civilian "Fillibuster" persona could use a Winchester 30-30.
The Boxer Rebellion is a treasure trove of weapon possibilities, and its 1900 date means it can be used for both the Victorian Main Match and the Expansion era match.
I've thought of passing as a Masters Mate off the SS Gussie, a well known gunrunner in Cuban Waters, wielding a Webley Top Break and a Mauser 91 bought in the weapons black market of Buenos Aires . . . In fact, come to think of it, I'll do exactly that for this weekends "Hi-wye-an floweredy shirt match" at my local SASS club (which has a military category just for us GAF types.)
