I stumbled across the page mentioned above before. Any opinions on plain base GC's, and do they work on bevel base bullets, or only flat base?
New to casting and coating.

Plain base checks are for plain base bullets

Is a bevel base not also a plain base seeing it doesn't have a groove/GC shank though?

Bullets such as this

Doesn't matter though, I've e-mailed the company.

You may or may not have issues with the checks depending on the height of the bevel vs the height of the rim of the gas check.
just reading on this myself too, hadn't heard of gc for pb or bb, but they are, seem to be smaller dimension than regular gc's
found some info sagesoutdoors.com/plain-base-gas-checks/
seems like the sizer works the lead to the correct size including the thin gc resulting in it sticking
todays learn for me
Here's my earlier lesson in pc'ing. Being new, for me everything so far is a trial it seems.
Leads started out .381, tried some of a free-to-me powder and it wasn't sticking very good
So as a tin of acetone was sitting handy after cleaning the leads and remembering vague details of doing a powder/acetone slurry as a coating mix, I dropped in a few drops and presto! instant goo. Surmise it was too much powder with not enough acetone but the consistency was goo-ier than honey, had trouble even dropping them into the rack for baking
Result has good first appearance, good coating and passes the smash test but way way too thick. Wound up being .385 to .388 with variance on each, I think due to the goo sticking to the glove and not coating evenly to start, finger pinch spots were thinner than untouched.

Keep trying. I've only just started pc last winter. I like the idea of no lube, no leading. I usually only shoot lighter loads, so pc is made for me! The only "extra" thing I've tried was washing the bullets in acetone, let them dry and then pc. I just lay them out, try to keep the separated after pc'ing, then stuff them in my wobblemart toaster oven.
get a cheap hot plate and a lead casting thermometer. preheat your mold on the hot plate and get your lead temp up just a bit if you are using WW alloy. all of the bullets in your clip show the symptoms of a cold mold just judging from the bright shiny appearance and wrinkles in the bullet. you are quite close to dropping good uniform bullets, just get a bit more heat into the mold blocks. also if you can find some solder or pewter, add a bit of it to the pot, it is like cheating to get a well filled cavity and sharp edges on your bullets.
I normally add some Antimony and tin, this batch I forgot to, Lesson learned. The .41 cal mold is brass or bronze, it takes a while to heat up to temp. The .355 and the .312 are generally GTG after about 3 castings, as I let those sit a few seconds in the mold before I drop them. I'm using a LEE casting pot though. Thank you for the tips.
