Thread: Loading .577 snider?

The stack you describe will work fine.You can experiment by weighing the amount of filler but it's not a good idea to have to much compression in a bottle necked case as it will increase pressure.

Wether or not you actually need a filler depends on who you believe. I don't know enough about the subject to say either way.But if you have a load 80% or more of the service charge,I wouldn't and havnt bothered with a filler.

What action are you going to use for your project?
