Sumatra Magazine .25 cal

Work great. I bought a bunch

Read where some said they were bigger than originals. Cant tell. They same as ones that came w/ my rifle. But i bought my Sumatra used w/ unknown history at an estate sale on the cheap. It has SamYang and AirVenturi stamped on it, not Seneca or Cleveland Ohio. Read where some grind or file grooves in them to put an o-ring around it to hold slugs or pellets more secure. I havent foundt need to do this. Hunter supply 48g slugs fit perfect as have all pellets. But H&N Grizzly fell right threw. Im thinking that means they too small anyways. Plus theys many better slug choices. I use a red perm sharpie to mark #1 hole so i can see it easily when it rolls back around after shot #6. Engraving #s are hard to see in day light. Read where ball bearing seemed stiff on one dudes. Mine work perfect, all of them. They slip right in/out like they ought to

I love everything about these,great quality . Bearings are tight and smooth and operate well

Nothing they exceed what I was expecting

The bore is larger diameter than the original that comes with the gun. JSB H&N grizzly etc. just fall in but doesn't affect accuracy I started buying custom swaged bullets and they do great

Metal not plastic

I would machine a ring like the Hatsan rifle magazines and use an O ring as a method to contain pellets in place for transport

Pellets will not stay in magazine
