    Projectiles stick in sizing die

    Iím looking forward for possible issues that I donít know about if anyone has similar experiences.
    A few weeks ago I cast up a batch of my favorite 300 blackout projectiles. Iíve only used straight w/wís and always water drop them. I usually resize from 311 before pc to 309 without any problems. A few days ago, I ran the cast projectiles without pcíing through my Lee push through resizer. After about 20 rounds, the next round got tough to push through but went. The next round was very difficult to push through, but looked normal. The next round got stuck. Like really stuck. Iíve had 4 more consecutive projectiles get stuck.
    Iíve ran +1k through this resizing die without a hiccup. I have another projectile stuck and canít get it out so I ordered a new resizing die. I donít want to ruin this one too. So whereíd I go wrong? Was it in letting the projectiles sit for a few weeks (like 6 weeks) before I tried to resize? I have ran them before without pc, but never after letting sit so long between steps. Usually I resize the same evening as they are cast.

    I use water dropped wheel weight bullets at just under 0.311'' and size to 0.310''. If I try and size after even a few days it can be a tough job. Had some bullets that had a little zinc in them, and I could feel every driving band as they went through the sizer. The only way to get them through the sizer was to use plenty of lube in the form of aerosol furniture polish, if not, they will stick.

    I did not see your pics when I first replied. You have a lot of bearing surface with those bullets causing your problem. Melt them down again and size them the same day.

    Spray them very well with Hornady spray case lube. But powder coating after will be a problem unless you clean them with denatured alcohol or something similar in a towel to remove the remnants of the spray lube.
    We Know Mass Cannot Be Weighed But It Has Newtonian Weight And That Is Derived From Kilograms And Kilograms Can Be Converted to Pounds. But, Still Mass Cannot Be Weighed. But How is the kilograms obtained? Can Kilograms Be Weighed? Evidentally Yes It Can. But, Still Mass Cannot Be Weighed So Kilograms Must Not Exist. Funny Isn't It.
    One good thing out of this the next time I'm at the doctors and they want to weigh me I'll tell them mass cannot be weighed.

    That is probably what Iíll do. The thing is, I cast about 2k of them. I had rotator cuff surgery in July. I knew it would be a while before I could cast anything so I cast a bunch up knowing I could still do the one-handed operations like resizing and powder coating while I heal. Oh well. Back to the drawing boards.

    I donít want to lube them. I tried it once. It made sizing really super easy but I could never get the projectiles clean enough to get pc to stick.

    2 thousand bullets is a lot to recast. I think I would try 44MAG's suggestion first.

    This might not even need case lube.

    BTW, why are you water dropping them don't you loose the hardness after you PC them? Do you water drop after PC?

    I PC then size. Then back into the oven for heat treat, then quench.

    Just donít put Kroil on the boolits or die. Youíll learn what stuck really is. I only did it once.

    I always resize boolits after PC'ing and I use a little Ben's Red on about every 10th boolit to lube the sizer... That's just what I do.

    I use Dawn dish soap as a sizing lube in my Lee sizing die.
    After PC, I put 100 or so bullets in a small Tupperware bowl, a dime size squirt of Dawn and snap on the lid. Shake like LLA and size IMMEDIATELY. Rinse well in hot water, pour out on old cookie sheet. Let dry in the Sun.

    Use half the Dawn for successive batches.

    Never had a bullet stick. When finished rinse Die in hot, hot water. Dry in Warm Oven or in Sunshine on top of Bar-B-Q Grill.
    I HATE auto-correct
