Anyways, I have around 800 rounds through it. Looking down the barrel, the leading edges of the rifling look nice and square still. When cleaning it, the rod has quite a bit of resistance at first, then it smoothes out for the rest of the barrel. I'd say that it's the first inch or so.
My accuracy isn't what it used to be. Is it time for a new barrel, or can I do something to smooth it out and get next summer out of it?
Thanks for your time, Eric
This sounds like carbon and/or copper fouling and can be removed.
Start cleaning with a strong solvent Like Sweets (I prefer Butches bore shine) and with
the muzzle at a good down angle (I dont like getting the solvent in the action) and give
the bore a good brushing, then let it set for 10 or 15 minutes.
Push a patch through the bore and repeat the process until the dry patch feels smooth
all the way down the bore.
The throat area get the most fouled and sometimes needs extra cleaning.
With only 800 rounds through the barrel it should be fine.
After a bare metal cleaning use a swab with a mild solvent (Like Hoppe's #9 and do a final cleaning to remove any of the strong solvent and a lightly oiled patch to protect the bore
until you shoot it.
This process may change your zero for a few shots until it gets seasoned so don't worry,
and most of the time it improves the accuracy.
There are carbon solvents but I have never needed to try them.
