Check the listing for details. 5 custom brass speed loaders for loose muzzleloader powder 70-75 Grain Cap.. Listed at 15.99 USD. I have available 5 custom made speed loaders ( vials tubes ). These were made from 30-06 brass cartridges that were previously fired. The neck was then machined to accept a threaded cap. Each speedloader will hold approximately 70-75 grains of loose black powder or equivalent. My son and I use these for going to the range and hunting and they make it much faster to reload. We have tried the clear plastic vials which became brittle and cracked over time and we came up with this great alternative we have been using for several years. These are brass so you must take care that you do not force a cap on if it cross threads. (My 17 year old hasn't done it yet) (nor have I) Thanks for looking. I only ship in the 48 contiguous states.
