There are many other ways to clean that may work for you. I know those who believe aggressive bronze brushing works well for them. As a general principle, however, with a really good-shooting barrel, I take the conservative approach. YMMV.
I switched to Boretech a few years ago and use it exclusively now, if you haven’t tried it you should.. I’ve seen no ill effects with using a bronze brush..follow the instructions on the Boretech bottles..This is one of those issues where there are a lot of opinions and few facts. I'll add my opinion.
In season, I clean every 30 rounds. I normally only shoot 10 to 12 per range session when practicing so I don't necessarily clean after shooting. I clean based on round count, in season.
About a year ago I switches to Bore Tech products because the smell of Shooter's Choice was driving wifey crazy. I was very impressed with Bore Tech and now use it exclusively.
Since I believe that a bronze brush is desirable to prevent a carbon ring I opted for the two part Bore Tech system. I used their Carbon Removal, C4, with a bronze brush. After dry patching I run a couple of patches of their copper removal, C2, down the bore. After the specified dwell time I dry patch. If I see evidence of copper I go to a full C2 treatment with 15 passes of a saturated nylon brush. Every 100 rounds I do a full C2 treatment.
If you use Dewey no harm bronze brushes and a rod guide you won't harm the bore using a bronze brush.
+1 on this method , it works for me as well... If I just can't get something stubborn out , a few strokes with a brush and re-foam , then an oily patch followed by how ever many dry patches , depending on how long it will be stored...For most rifles that don't foul a lot, I'll run 3-4 soaking wet patches through bore. Then apply Wipe-Out foam. I wait about 20 minutes as the bubbles dissipate, while I'm loading my gear into the car. Then I reapply the foam, and plug muzzle and breech. I drive home and patch out about 3-4 hours later. That's it. With other barrels I might brush a little to remove hard carbon -- but I rarely shoot more than 70 rounds in one session and the wet patches and WipeOut takes care of that, if applied right after you shoot.
With the Wipe-out, no carbon ring after hundreds of rounds with Varget and H4350.

When I finish shooting I normally push down a patch wetted w/ powder solvent followed by a dry patch followed by a patch wetted w/ Kroil. Is this good enough or should I fully clean the barrel after a shooting session. BTW, I typically shoot 20 to 30 rounds per session.
I am in T-Total agreement in regards to the use of bronze brushes. I will tell you a "For Real" story. I bought a Rock Creek (before he went military for awhile) 30 cal barrel for a .308 build. I said to myself "if I start right from the get-go and NOT use bronze brushes, ONLY very stiff nylon brushes, along with A GOOD SOAKING of Bore-Tech Eliminator, should maintain a clean barrel". As usual, after about 400 rounds back then, I took my rifle to my smith where he would check with his Hawkeye. I had LOTS of carbon, ie. HARD CARBON build up for nearly half the barrel length! So my "experiment" took me to the conclusion that without a GOOD scrubbing with a bronze brush AND fairly periodic scrubbing with either JB Bore Paste or Iosso Bore Paste, you CAN NOT get the hard carbon out of the barrel. Fortunately for me, I only let it go so far. Yet, I remember the ALL AFTERNOON into the evening of scrubbing to get the carbon out! Horrible! Do NOT let it get out of control in the first place!A little powder or copper fouling is no problem. Hard carbon is. Its not something you want building up. Different cartridge/powder combos will carbon foul at different rates. When I get phone calls regarding carbon build up, the first thing I ask is, are you using a bronze brush? The answer is always no.
It's easier to KEEP a barrel clean than to clean a really dirty barrel.
A clean patch tells your nothing, only a scope does
