Home Forums Reloading Shotshells Reloading a 410 with a Lee Loader

New to shotgun reloading so please be patient.

Just acquired an ancient Lee Loader for 2.5 inch 410. This is old, no plastic dippers, no styrfoam inside, no pictures of shotgun or rifle shells on top of the box. Has hard cardboard inside with appropriate holes for the tools. No instructions or reloading data. I use a 410 for early season blue grouse in the west when they are dumb as a box of rocks.

Questions:

Will this tool star crimp new plastic casing or is a roll crimp my only option?
Where can I find low pressure reloading data?
How old is this thing?

Thanks and apologies to all the grouse hunting purists out there.
