Is there a difference in plungers for using #11 vs 209 primers in a bighorn? Is the #11 plunger longer and the 209 plunger shorter? My bighorn came with 3 breech plugs. 1st Breech plug for #11 and Musketcaps 2nd breech plug for using a 209 primer naked.(breech plug is magnetized, and the 209 primer sits snug) and 3rd breech plug for 209 primer set in a RPJ/FPJ.
