    Apply gas check, THEN tumble lube?

    Or the other way around, or is there any difference in gas check adhesion?

    I like to do a light coat of BLL, apply check. Smack the nose of the boolit with a rubber mallet if required to seat the check well and square, then size and 2 more light coats of BLL.
    I truly believe we need to get back to basics.

    Get right with the Lord.
    Get back to the land.
    Get back to thinking like our forefathers thought.


    May the Lord bless you and keep you. May the Lord make His face to shine upon you and be gracious unto you
    and give you His peace. Let all of the earth – all of His creation – worship and praise His name! Make His
    praise glorious!

    Check first. You do not need a coat of lube between the bullet and the check.

    If I don't apply the GC before PC I would never be able to get it on. Some I tried after PC & it was literally impossible to even begin to get the GC on.

    If you're powder coating, do you need a gas check?

    It depends on the velocity. At low speeds probably not. I shoot 12 Bhn PC boolits at 1980-2250fps and get sub-MOA. Not trying those without a GC.

    I guess it depends on mold, how much PC and what checks. I do it both ways depending on what I'm trying to do, but if possible I like the check sitting out there all nice n shiny hoping they will scrape out any errant residue as it goes on it passes by.

    I have had to deburr the bases or expand the checks on occasion though. Gotta love all those handy NOE tools.

    For that reason, I gc first, then pc, then resize.

    I do both ways,too.

    About this "scraping effect", I loaded some rounds with the GC:s only seated (with the Lubrisizer seating tool). You can even see in the pic that the GS's are larger than the bullet. Bullets had been sized, GC:s not. They loaded and shot fine, this is only a 325 grainer. Standard 470 NE is 500.

    Do they actually "scrape"? All I know is I cleaned old copper out of this gun for two days, using Bore Tech products and it's fired only cast ever since. A few weeks, 150 rds. The other day I did a deep clean and some blue came out... from gas checks,maybe?

    So many options in this sport.

    Petander,

    sounds like unsized scraping is a bad idea. They say copper in the barrel is a lead attracting magnet, we don't need any of that.

    Subject shift, is that a recent pic? I've been wondering when your world turns white up there in your neck of the Finland woods.

    Yes copper is bad. But even a sized GC leaves some miniscule amounts of copper doesn't it? Those Bore Tech products find it all...

    Yes it's a recent pic. No permanent snow in my area ( 62 N )yet, drive a few hours up north and there is snow and frozen lakes.
