Barnes bullets are notorious for fouling,but I use them in a lot
of my rifles anyway.
Barnes has thier on solvent that works well but there are lots
of good copper solvents that will work.
Normally I clean after 3 to 5 rounds when using the barnes bullets
or molly cote them if i plan on shooting a lot.
I never use them to break in a new barrel because of fowling.
The triple shock appear not to fowl as bad as the x bullet and
the XLC's when you can get them work well.
1 example of this problem = I bough a 416 rem mag years ago
and hornady and barnes were the only bullets available at that
time. wanting to use spitzers I bough the barnes.
After loading 10 different loads I was off to the range.
Started shooting and could not find an accurate load (around
1 MOA) so after 50 rds I gave up .The fun had gone out of it.
When I got home it was time to start cleaning the beast, well
4 hours later I was still removing copper.
This was a factory barrel so I contribute some fowling to this
but never again will I shoot that much with out cleaning.
Under hunting conditions this should not be a problem, so if
your rifle likes them use them but clean often.
