I been reading some other posts on the 250g charge talking how it's not accurate and sight the gun in and not the scope! Im kinda leaning towards that too! The first four shots I am very happy with at 100 yds the last two very dissappointed in. My question is why did my first four shots shoot so good and then the last too suck?? I was swabbing in between shots. Could it be dirty gun/breech?(bench rest shots)
