Just placed a 209 primer in the gun and did not have a problem with it. by the way it is the pursuit LT model. hung a scope on it, dying to get it to the range. only problem i see so far is the trigger pull, seems a little strong to me. was hoping that mygirlfriend could use it, but she might have to use two fingers. also looks like that ramrod is just a little too short, but i can work around that.
