Today was my range day and as usual I headed toward the range and fired approx. 130 rounds. As many of you know, presently I have been using Power Pistol powder, 230gr RN Berry plated bullets and Winchester large primers. My powder load of Power Pistol is :6.7-6.9 grains. I have noticed this before on my targets using the Power Pistol powder vs. TiteGroup. The holes from Power Pistol seem to be elongated whereas the TiteGroup holes are perfect circles. I measure powder on every shell I load so I can maintain my consistancy. Accuracy also seems a bit different from TiteGroup. The TiteGroup tends to have a slight tad of better accuracy. Does the oblong holes indicate that my rounds are starting to tumble or "boat tail"? This is not a 1 time thing, I have noticed this quite a bit lately. I have noticed this from 28 feet to 40 feet distance. Beyond that the targets really get fuzzy with these old eyes. Any explanation would sure be appreciated.
