Update Tinbum pellet sizer

Hello my friends!



today it was a pretty good day for some comparison between the original .25 King heavys and my resized ones.

booth pellets were shot at the same weather conditions with the same rifle at the same speed at the same distance.

Target distance was 60meters or 65yards.

every group was shot with one mag. (11shots)

i have marked the centers with red 🔴.

Correct me if I'm wrong but unless I'm mistaken the TBT sizers are size specific. Maybe you just got the wrong size for your specific gun/barrel.

Hello.



at krale were I bought it, there was only one size available. So I can’t choose different sizes.

and there was only 6,35mm to choose.

no specific numbers like .250 or .251 or .252 and so on like other brands do it.
 
I noted that with later reading on the TBT site, Patrick. Odd that they make 6 sizes for .177, 3 for .22, and only 1 for .25. If the sizing can be that important for the smaller diameters then why would it not be at least somewhat important for .25? Less than logical to my mind. Have you compared fit of the sized and unsized to the bore? Are the sized pellets noticeably looser?

Keep you’re right! So the same here, I don’t know why they only offer one size in .25.

no I haven’t compared it strictly, I only noticed a big difference when cocking the gun, with the original there was a resistance and the sized it’s butter smooth. But maybe I have to shoot more resized pellets for the lead built up in the ST Barrels and out of that accuracy was better, so I only have shot 1 mag of the resized ones.
