Easy.


Dry off after hunting. Clean and lubricate your guns and Yes the barrel.
Keep the humidity down in the safe or place you store guns. Don't use Corrosive ammo, including primers.






Now ask me how to clean up a rusty barrel and prevent further pitting.

It was fast, forgot to clean the bbl just one time... maybe 2 months left alone and now pits.
What causes that? Is it the carbon?
Ive only used cci br2 primers in this gun.

Sure, tell me more about preventing. I usually clean to bare metal then coat with clp oil.

What firearm is this? Does it have a chromed bore? That's surprising that a barrel would show signs of corrosion in just a couple months, unless it was used with black powder, or corrosive primers.

This is a fairly new Douglass barrel on a Remington 700. Maybe a year and a half old, only handloads and never any pits but i always cleaned the bbl after each range session except this one time. no idea if its chrome lined but doubt it, was never mentioned from the smith...

As noted those are pits.
Prevent....dry , clean and oil your bore.

All that said....
I have seen and done good shooting with rifles that had a pitted bore.

You can bet I will be more thorough and timely on cleaning from now on. Ive also had good shooting rifles with old pitted bore, im just disappointed (in me) for letting this happen on a new custom barrel. This gun shoots sub 1\2 in moa so hopefully this doesnt change anything.

Look at storage. If you are getting rust, the storage place likely has humidity. Rust won't form if humidity is kept at 50%. Pitting type rust usually indicates it developed relatively fast from water or high humidity.

I don't know I could call that pitting from rust without seeing rust there or on patches. Might just be defects in the steel. Either way it likely won't effect accuracy. I have barrels with a hole in them that shoot very good (there there for a gas port)

Carbon in the barrel can attract moisture.
If you don't clean it immediately at least run an oiled swab down the barrel.

I have had some expensive barrels get minor pitting and I can't say I saw any negative effects.
