It's a good ad-on if you are going to dedicate it to one cal, it is a tight fit but once you got it set up it's pretty neat, I took mine off, just don't really have a need anymore, I think I put about 500 45's thru mine, it's just now sitting here in a box along with about 15 tubes------------it is available. If you are interested give me a PM and we'll chat.
When I posted, I was thinking bullet feeder for the lube sizer, sorry for the confusion.
