5.7 brass

Just curious, do you think it could be the meplat or ejector pin size?

it could.
if you try to push the nose hole too small it will form around the ejector pin.
try backing the die off about 1/8 turn.
I know every time I change something in my process [jackets-core weight] I have to basically re-set my dies up too.

Duke and I found that you have to have all of the coating off of the case. We anneal them at 800 degrees for 20 min. and then we use ceramic pins and tumble for 3 hours. they come out spotless, they look like cooper when they are done. We rinse them thoroughly then dry. Once we core them they are cleaned again with a non petroleum based cleaner and lubed in a zip lock bag. This way they have no contamination on them and we have point formed several thousand now without a problem. We wait till we get a 5 gallon bucket full then start our swaging process. Duke has the chore of finding and getting the 5.7s and somehow he comes up with a 5 gallon bucket full about every six months. He is very protective of these little devils. There are 3 of us that go in together on the different steps in the process cycle. Then we all come together at Dukes and have a swaging party to core them and point form. It takes us about 4 swaging partys to complete a 5 gallon bucket. Then we split them up and go shoot them. We have done in the last year several thousand rounds. we swag 150 grains mostly for our blackouts, but also 168 for Dukes m1 Garrand 308 and I just bought a model 12 savage varmint rifle to shoot the 168s also.

Where is the least expensive place to get the SS pins?

[DukeInFlorida]

STM, the vendor right at the top of this page, is the best place for the pins.

However, if you re-read PeeWees post above, we are using ceramic puns for cleaning the burned plastic off the outside of the cases after annealing. Those ceramic pins I got from a vendor on the internet that specializes in such things. Bought two pounds for a good price, and they work better for this task than the SS pins do.

Good to know Duke thanks. I will look into that, triangle shape right? Are you using a tumbler or a vibrator tumbler?

[Pee Wee]

We are using a rebel 17 wet tumbler. However you only use a half cup of water, one oz. of liquid soap and one oz.of lemi shine. Tumble for 3 hours.
