I think i have well over 80 of them now. They have so many uses. I store #11 caps, 209 primers, my inserts for powerbelts, Hell i even put some tru oil in one and screwed the cap on and sent it to forum member corey so he could add a couple coats to the barrel i had browned for him. They dont leak!
Heres some pictures to compare. I HATE these TC speedloaders as you have to load the powder on the nose of the bullet. Every time i push a bullet down, the face of the bullet would be coated with powder. That does not help with consistency.

Thinner neck makes for easier pouring down the bore. Plus they wont pop open like the other speedloader does. Nothing worse than that happening and wasting good expensive powder.
When i go hunting i just load of 3 of Lanes powder tubes and then fill up the another to carry my bullets. I like using the small tubes as i shoot lower powder charges and they leave me with more room in my possibles bag.
You'll love them when you get yours. I also believe he has green caps as well, Along with Red and White.
