Complete Magazine and Loading System - (1) Magazine, (1) Stud Feeder and (4) Stud Mag Loaders
Feeder/Loaders
System elminates the need to hand load any pellets into Stud Mag Loaders
Designed to sort and stage Diabolo Pellets
The magazine will NOT properly stage pellets (in the STUD Pocket) with oversized diameters, such as JSB DIABOLO EXACT MONSTER 25.39g etc. STUD Magazines are designed for standard diameter pellets/slugs only.
The magazine WILL NOT feed really short slugs like 25g Zans. These slugs do not have enough of the slug main diameter, to feed correctly
STUD FEEDER WILL NOT sort JSB DIABOLO EXACT MONSTER 25.39g (these are a larger diameter than a standard pellet)
The FEEDER will NOT sort slugs or "Flat Top" style Pellets
 Magazines will feed pellets or slugs up to 13mm (.512") in length.
