I used to have a very complicated regime for cleaning and clean they were when finished. As to the heavy ammonia solvents, CR10 and Sweet's, if left too long in the barrel, it's true the more you have to use them. I let them sit for no more than 10 minutes, then patchout with 2 patches, dropping off at the muzzle, then oiled with hoppe's #9, just for the oil in it. Nowadays, it's a poor cleaner - in comparrison to days of yor, but does have use for it's oil content.

Nowadays, when cleaning at the range or during a day's shooting of gophers in the field, I use Butches, once or twice, cut 50/50 to 70/30 with Kroil oil, then patch dry and continue shooting.

Once 'home' or at camp, I spray some Wipe Out into the bore and postition the rifle with the muzzle slightly down for an overnight sit. In the morning, I patch it out and it's clean. One patch using butches w/ kroil and wipe dry with 2 patches, falling off at the muzzle, then start shooting again.

Wipeout makes complete cleaning a modern rifle easy - but remember to use something with oil in it to re-wet the bore, wiping dry with 2 patches, falling off at the muzzle.

Works for me.
