I have 2ea. 8 inch barrel model 53s . one in a factory wood box and the other in the blue box.Both have the extra 22 cylinders. These guns are great fun to shoot and to load for. You can get the remington brass and Hornady .222 bullets from Midwayusa.com.
the brass sales are seasonal only sold once a year. Searia .223 dia. bullets are the most accurate to shoot you have to reduce the loads.
