Things I liked: The speed-loader is great and I reload them with other brands of BB's that do not have a good dispenser. Other than that, this product presents a giant "IF". IF your gun can use these "steel ball pellets" as I will label them due to their over-sized diameter as addressed in the last section of this review, they may serve you well. But you should be aware that they may also create a situation that may disable one of your prized BB pistols or rifles and cost you money to remedy the situation. This makes giving these a rating very "IFFY".

Things I would have changed: That the manufacturer reveals the nominal diameter of the product and alerts the user that they are larger than the industry standard and may jam in some barrels. (Not only do they jam, they are nearly impossible to remove from some designs unless the gun is disassembled to prevent damage to the mechanism.) Until this is done, my rating for size, shape, distribution will have to be 1-star, "bad"

What others should know: I know what makes it jam in some barrels. I measured ten randomly selected BB's from some with a micrometer and they run .1765" nominally. They are exceptionally uniform in diameter ranging from a low of .176" to a large of .177" with the bulk of them measuring .1765". However most production BB's measure from .173" to .1745" as the industry standard, so these are most definitely over-sized. These BB's can be some of the most accurate types you may find for your gun and they have shown excellent accuracy from several of mine. I no longer will even attempt to use them in a pistol with a spring loaded stacked magazine with a blow-back action (as the UMAREX Legends P.08 blow-back). If one of these type guns jam within the barrel, they must be disassembled or returned to the factory and may not be warranted due to the projectile recommendation usually given. I now limit my use of these to non blow-back designs or revolvers using "cartridges" or rotating loaders.

Things I liked: Speed loader is somewhat useful though it's very hard to control the flow of BB's. Also, I noticed that some BB's flowed out of the tip easily while others did not (more on this below.) I will use the speed loader as a smaller, transportable-in-your-pocket BB holder.

Things I would have changed: I would add a disclaimer - Do NOT use in a Swiss Arms .357. My first attempt to use these in my Swiss Arms .357 (6" barrel) caused a jam. I dislodged the BB and tried again. Same problem on the first shot. After the third attempt (and third jam), I gave up and went back to using the cheap BB's which came with the .357 as well as the free H&N Smart Shots, both of which worked just fine. I noticed that when loading the faux bullets with the Marksman BB's, the fit was tighter than the other BB's I had used. Should have been a warning sign... oh well.

What others should know: Since I didn't want to just throw these in the trash, I tried a few in my trusty old Marksman 1010 and low and behold, they worked great and shot very accurately. Go figure... Marksman BB's in a 25 year old Marksman pistol yielded a 1" grouping from about 12 feet (never thought that would be possible with my 1010.) Not sure if this is related, but I loaded up a brand new Umarex 9XP with these Marksman BB's and it failed to fire on the first shot. I had to return the 9XP as it would not fire a BB after this first attempt. Coincidence... maybe.
