If you're serious about using the best ear protection possible, the Surefire EP4 Sonic Defender Plus Triple Flanged Earplugs should be in your range bag.

Three flanges on the stem of each earplug form a tight seal in your ear canal, guarding your eardrum from the damaging noise of gunshots. But the unique design of these earplugs allows softer noises to pass through, so you don't have to remove them just to have a conversation. If you have no need to listen to anything else and want to block out as much noise as possible, you can do this by putting on the included filter caps. The retention rings keep the earplugs in place without causing discomfort. The low-profile design means that these earplugs won't interfere with your safety goggles, helmet, or headset.
