Well, we did study shotgun bores/gauges in an earlier post. But it is hard to visualize the effects of the different gauges from just a description.
No fear, the lovely and talented Heather LaCroix is here, demonstrating the effects of 10 gauge vs. 12 gauge vs. 20 gauge vs. .410 caliber (67 gauge). Remember from our earlier discussion of how shotgun gauges work, the smaller the number, the bigger the diameter of the cartridge and the more powerful the gun.
Thanks to Heather LaCroix and Jeff3230 for the demonstration.
