[QUOTE="baydog, post: 1022392, member: 76072"] Hi Tim..Yes the target with the 4 different powder test shots or the target with the most holes was shot on a day that was almost 60 degrees but the day I shot the 2 different powder load shots or the target with the least amount of holes was shot on a day with the temp. in the low 40's ..almost a 20 degree temperature change..The target with the most shots in it was all shot in the same day. I would shoot 2 shots and wait at least 15 minutes before shooting the next powder charge change. I need to shoot at least 3 diffrent powder loads with the retumbo powder and same bullet to give it a fare chance but I have done that when I first started shooting the gun. The retumbo was the first powder I shot through the gun and was not happy with the groups I was getting so started trying diffrent bullet depths and powder charges. Came up with a depth of 3.747 but then realized that if I wanted to shoot that OAL I would have a single shot because they would not fit in the magzine andcame up with 3.620 as a OAL..Isn't it a diffrent magazine I can buy to get more over all length?
