Have you ever patterned a shell / choke combo that made you wonder if there are even pellets in the shell? I don't care what you aim at when it's like that. And please don't just say practice more, everyone knows practicing shooting and taking smart shots is a huge factor. If you're a good shot he shell and choke applications absolutely matter
This. Out of curiosity, I patterned some old, el cheapo Remington #6 game loads, and it made me wonder how I'd ever hit anything at all. When compared to the modern Remington XLR loads, they were downright pathetic. I'll grant you the new loads cost twice as much, but the money appeared to be very well spent from what I could see.
