PGN Steel Slingshot Ammo - 1/2'' Inch (0.50'' Caliber) - Straight & Precise Practice Ammo

They definitely fit the TR50, these just require a harder push when loading it’s not the soft ball so it’s not gonna just fit right in, and I definitely won’t say it didn’t hurt my fingers a bit loading these especially because after loading the soft silicone balls so easily the need for a tough grip and a little strength to put these in was a bit surprising as soon as I loaded it I went to take a shot at first I thought it was jammed but I also had to pull the trigger with a bit more force as well and as soon as I did I shot a hole right through a bucket 🪣 I won’t be able to use it for mop water or water balloons anymore but at least I know it works, the shot is powerful and I have no regrets. Good Buy!

Bought these to replace steel balls for the game Bullseye Ball and they are exactly the right size and weight. The tolerances/variance of these replacements are right on par with the original game steel bearings.Measured with a micrometer and weighed in grams to 2 decimal places, the bullseye originals and these are all equally close to the correct ideal size of 0.5" diameter, and 8.5g.These steel balls work with the game and there's no appreciable difference when using them. Visually they are slightly more grey than the originals. My daughter could not see the difference but I was able to notice the originals are ever so slightly more bright in their shine.With a pack of 100 for $20 I don't ever have to worry if i lose any; I will have plenty for the game. Adding extra to the game tray also makes it easier to score points faster. I also have plenty of steel balls should I need ammo for a slingshot in the future.

My only nitpick was the inside of the bag was a little smudged, but with that many 1/2” bearings it’s bound to mess up the bag

I tend to have wildlife show up at my house, they work great to scare them off and not hurt the wildlife. I shoot something beside them to scare them.

I use this ammo to shoot out of my modified pepper ball guns. Sizing and weight are consistent and accurate. Good product. Wish it were cheaper I go through a lot.
