Remington Goldens clogged my 617 after only 100 rounds. After scrubbing the chambers of carbon fouling and lead strips in the barrel (a little on the top strap as well), I grabbed up all of my remaining Goldens and burned 500 rounds in one session at the local indoor range, alternating with my Single-10 when the cylinders got too warm. I did take a brush and dry brushed the chambers after every 50 to keep both shooting. I shoot CCI and Aguila in both now, and barely any fouling occurs. All .22's are dirty. Cheap ammo is very dirty.
