I’m just trying to learn as much as I can about the sport of “Groups” and “Score.” And, I’ve been around long enough to know that what seems to be the obvious answer, is not always the correct answer. However, something inside of me tells me that if the 6PPC wasn’t the best cartridge for group shooting, most people wouldn’t be shooting it in serious competitions. Now, a new (to me) point, I believe, has been brought up. That’s the point that the rules for “Group” are bent towards the 6PPC. Am I understanding that right? If that is the case then the 6PPC seems to be the right cartridge. At least, until the rules are changed. I don’t know…….maybe I misunderstood the part about “rules and regs.” It’s hard (at least for me) to grasp what people try to say (sometimes) in writing. You’re not able to see the facial expressions and the inflections and tone of the voice. I can often “think” that I know what is being said and end up all wrong.
