I purchased this 5 Cavity mold from a member of a popular casting forum. It was described as being PB, but when it came it was actually a GC design.
My Enfield needs to have all of the .316. I believe the bullet will need to seat deep enough that the base will be below the short bottleneck of the 303 case, so the check needs to be secure.
I need to buy checks as I have none. I do not have any other small rifle molds, so I do not want to get the wrong size checks.
Will the 30 cal checks fit correctly, or do I need to use the 8MM checks?
I had intended the bullet to stay in the 13-1400 fps range as a PB. Is there any chance this GCed design would work in this speed range without any check?
I am new to casting and even newer to gas checks, sorry if this is a no-brainer question.
Thank you for your time, Tim.

I have that very mold.
Of course the (imho outrageously) expensive branded checks, eg Hornady, snap on just fine with finger pressure alone provided the base was cut clean from the sprue.
The ‘home made’ checks work very well, I used copper and aluminum checks from various vendors with no problems, but I like to seat home-made checks on square and true using a home made check-seater die, as the home made ones can be a bit tight.
Plain old 30 cal is the check you want. All I ever use.
