Here is a foam cleaner that works very well. Still, wear eye protection and keep the cleaner off your clothes. This will clean your rifle down to cold steel. You may be surprised at how many times you have to use the foam cleaner before all of the copper is out......YMMV I no longer use a copper or nylon brush to swab the barrel.
You spray it down the barrel from the action end-learn trigger control because it wants to spray out the muzzle.
Let it set for the time on the can.
patch from action to muzzle only.
I always repeat at least once to be sure everything is out of the barrel.
Take it to range, fire a fouler, sight it in.
I clean my barrels after 20 rounds or a range trip.
I really like the Gunslick foaming bore cleaner better but there are some serious considerations to be aware of:
1. You must wear full eye protection.
2. I remove the action from the stock
3. Keep this off your clothes. It burns a hole PDQ.
4. I take the used cotton products outside and let the agent evaporate.
5. Keep the foam off your optics-anything plastic...the effect is permanent
This does a perfect job of removing powder, carbon & copper. I use it and feel it contributes to consistent shot to shot bullet plscement.
