On T3 anecdote: my 12 YO daughter, unknown to me pushed her T3 barrel first through the Namibian dirt on a crawling stalk, filling the entire barrel and packing the bolt face with sand. After explaining to her why not to do that, I mostly got the sand out of the barrel and used a knife to dig it mostly out of the boltface. She then shot a 3/4" group to test zero and killed a Springbok with it a few hours later.
