I shot some tonight and the accuracy was starting to fall off
That generally is when I clean mine, but I don't do a full scrub.
I just pull a dry bore snake through it a couple of times and then try it.
If it is back to poa I leave it alone.
If not, then I run the snake a few more times.
That has always worked for me.
To this day I have never scrubed my 204 and it has something over 400 rounds through it.
The same with my old 223 contender carbine and it has well over 2000 rounds down it over the years and still will cut holes at 100.
Some of my other guns need a scrubbing once in a while.
Yours may be different but give it a try and see how it does.
In the past I have seen a few barrels ruined by to much cleaning along with improper cleaning.
