Dirty vs Clean Barrel: Does it Matter?

In this video, we put it to the test using a Thompson Center Encore. We fired 100 rounds total and tracked performance by shooting six 3-shot groups after every 20 rounds to see how accuracy changed as the barrel fouled. From clean bore to dirty barrel, this experiment shows real group sizes, consistency shifts, and what hunters and shooters can realistically expect before cleaning their rifle. If you’ve ever wondered whether barrel fouling matters for your next hunt, range session, or precision setup, this test gives you a clear answer. 👇 Let us know in the comments: How many rounds do you shoot before cleaning your rifle?
