Things I liked:

Not ready yet.

Things I would have changed:

List the true diameter

What others should know:

I was 99% certain when i bought these that they werent going to chamber into my Hatsan 135 QE 30cal breakbarrel. But curiosity got the best of me. These measuer out to .315 inches on my micrometer while a JSB pellet measures out to .300. Assuming this was the case plan B is currently underway. Im tumbling these round balls in my rock tumbler till' they get to the right diameter.Ill update if date if they turn out to be worth the labor.

  • Spencer from USA asked:

    Will this fit the Hatsan BT carnivore .30

    • MaxStrokedShovelHead from USA asked:

      The thing w/ using RB in Hat 135 or any break barrel is the shape of the ID and choke of the barrell. RB need to be slightly bigger in a firearm w/ the power to push it threw. Thats where the pellet skirt comes in, it expands to fit the rifling w/ less drag. I own 3 Hat .30 M135. Ive checked RB molds for recycling all my spent lead. Which is alot. All the molds are .311 or .29. Theres just no exact 1 that works. 1 might get lucky w/ a box of RB. But if your shootn alot, theyll be damage. All 3 of mine have been tuned, filled to higher Bar making 35-40 fpe. 1 zeroed in for each available pellet. Its best to forget about using RB in a Hat. Theres no real upside to it

      • Garrett from USA asked:

        Will this work with the hatsan 135 .30

          I have a Hatsan 130S .30 and nope, nothing by this brand fits. That extra 0.008 is too much
