    Last batch I put a half turn crimp with a lee die.
    Shouldn't be low charge, I use 4.4 grains as per the instructions for a 230gr. FMJ, never exceed is 4.8
    Should I work up closer to max, like 4.7 grains and see if that improves performance?

    I shoot alot of Titegroup and find it to be one of the cleanest powders compared to W231 and many others. I shoot 5.2g with 200g jacketed bullets in my .45's. You might experiment with a little heavier charge but I suspect your crimp may need to be a little heavier. Rule of thumb I was taught is .0002-.0004.

    sounds like low pressure...try bumping the charge up or increasing crimp first.

    Ok,
    This brings up a even more important question. I was told not to crimp my 45acp's because of ejection problems. I crimp everything else I own. As for dirty powders. A 45acp at lower speeds shots great with Bullseye and it's very clean. Powders like Unique are very dirty but both shot close on paper. Choose a different powder.

    If you are shooting .45acp in an semi-auto, you need to be taper crimping your loads. It sounds to me like your crimp is too light, not getting your pressure up enough to burn clean. Try a heavier crimp before bumping up your charges weight.

    Crimp has nothing to do with ejection problems...Unless your loads are too light to begin with..A good taper crimp is important for the 45acp..One way to set your crimp die is to try them in your barrel (after you remove it from the slide).."Pop" it in the chamber...Won't seat to the hood?...Crimp some more....Sticks?...Seat the bullet in a touch more...Seats past the hood?...Back off the crimp die...If it "clunks" and is easy to remove...Just right!

    A roll type crimp is NEVER, EVER and double NEVER advisable on the 45ACP.

    The round requires a taper crimp for bullet tension. It head spaces on the case mouth. The case mouth rim needs to engage the end of the chamber to assure headspace. Roll crimping may allow the firing pin strike to move the case into the throat. When that happens the bullet may pop a ring of brass off and lodge it in the barrel. If you shoot enough crimped 45ACP you risk blowing up your gun.

    A taper crimp die is cheap and easy to use. It may just fix your ignition problem.

    PS; I have shot some tite group and find it to be very clean burning.

    Hello been out of town but as others have stated Taper crimp to about.469 at the case mouth is the preferred loading for many top BULLS-EYE shooters You might want to check your cases and Bullet. TZZ and Remington as well as REM-UMC are 3 brands that have thin case wall [:(]thickness . WW / WCC MATCH and Federal all are thicker[:)] Your bullet should be .452... This Combo will give you good Bullet Pull. Thus cleaner burn. "PRAISE THE HARD-BALL GUN"

    Is it so "dirty" as to affect function of the gun?
    If not, shoot, then clean.
