Thanks. I've added 2 vents to the 2 corners of the tip. The grubs are fairly small (7/8"), the vents i've made are 1/64" deep and 1/64" inch wide and I have 8 of them crisscrossing each grub. Does the venting sound about right, or is that too much air?

I've designed my first Aluminum mold which I'll be CNC'ing shortly. Venting / Fill Channels / 3 Registration pins are all done. Plastic and Injector is on order from luremaking.com, but it will be about a week before it arrives, until I physically receive it, and I'd like to get the mold made before. I'm stuck on one thing, what do the dimensions of the Sprue Gate need to be to fit the following Doit Medium Nozzle: http://store.do-itmolds.com/Medium-Injector--4oz_p_325.html Thanks.
