Crimp

Where would you crimp this bullet?

Never worked with a TL Lee bullet.

Go by the book. Look for the minimum OAL length and don't go lower than that. You can go longer if it works in your action ,but NOT shorter,it creates higher pressures (DANGER). Look for the weight and then look for SWC design in the data. thats where you'll find you info.
You didn't give use enough info to give you any numbers. ei....TL401-180 SWC,,,.TL.452-200 SWC

Crimp in the top groove and call it a day.

i use the top groove, and a light crimp at that.

Thanks. That's what i was thinking. It's a TL-430-240-SWC 90399 mold. I didn't know if you crimped these guys on the ridge or in the groove.
