I have shot BPCR silhouette at the ENGC and I'll be 80 by the time of the match, but I won't be there to put your prediction to the test, as I moved far away. You might run into my son, though.
You can most certainly have fun, but a .45-110 will be lonely beast at a silhouette match. To steal a line from Matthew Quigley " I never had much use for one". I have done respectably in long range BPCR with a stoked up .45-70, meaning paper patched bullets seated way out over 80 grs. of Swiss 1/2. Billy Dixon match at steel Comanches at 1500 yards. Much fun!
