Silicone pot holders are CHEAP and I found one that holds a .30 caliber bullet PERFECT. The only issue MIGHT be (it's not an issue to me) is, it leaves four little bare spots on the gas check where the silicone touches.
I used it this morning to do 750 Lyman 311413's that I sized .314 for my SKS. Not a SINGLE bullet fell over during loading and unloading.
If you're an Amazon Prime member, you can get 4 of them for $5. These do look different than the one I have but for $5, it's worth finding out. I just ordered these too. I figure if they're too small, I'll use them for .22 ....which I'm hoping they are. They look to be.

I think this is the one I have that fits .30 caliber.
