    Something other then the stuff it was keyholing with. If it was keyholing with the Tula then something like Winchester Q3131 or XM-193 should work.

    I could be just the ammo you were using.
    I was shooting some handloads with a 50gr Remington HP that was keyholing but none of the other ammo I was using was doing it, so it was just a case of bad ammo.

    I'm learning here so thank you guys for all of the posts.

    When I get to the range this weekend and:

    I don't notice any keyholing with brass but start seeing keyholing with last weeks steel then I know it ammo?

    If I see keyholing with brass and it steadily get worse, time for a new barrel?

    If I shoot steel and brass with no keyholing then it was just a really dirty barrel?

    Is the Winchester or XM193 match grade ammo? Local WallyWorld has Winchester Q3131 in stock and local gun shop has AE XM193 as well.

    No. Match grade will usually say "Match" on the box, such as Hornandy Match ammo, etc.

    The gun is cleaned and ready to test this weekend, but I think I'm gonna order a DD Lightweight barrel anyway.

    Thanks to all who have posted!

    I just got back from the range and I'm still keyholing. So I just ordered a DD 14.5" CHF Chrome Lined 1/7 5.56 NATO Lightweight Carbine Pencil Barrel From Grant.
