Final answer:
8 gauge shotgun shells are bigger in diameter than 20 gauge shells, and the answer is True. This is because in shotgun gauges, a smaller number indicates a larger diameter.
Step-by-step explanation:
The question 'Are 8 gauge shells bigger in diameter than 20 gauge?' refers to the sizing of shotgun shells. When comparing gauge numbers in shotgun shells, a smaller gauge number actually corresponds to a larger diameter shell. So, the answer to the question is True.
An 8 gauge shell is indeed bigger in diameter than a 20 gauge shell. This is due to the way shotgun gauges are determined, which is based on the number of lead balls with the same diameter as the barrel that can be made from a pound of lead. As the gauge number decreases, the size of the barrel increases.
