Good day all
I have purchased several different types of pellets, different manufactures as well as weights and shapes.
I have shot with my Umarex surge;
daisy wad cutter
stoeger xmatch
stoeger xhunt
crosman premier
jsb match diabolo dome 7.33gr and 8.44gr
Rws percision 7.0gr, pro line 8.2gr, field line 8.2gr
Gun shot best with Stoeger Xmatch second best Stoeger xhunt
With my Crosman Vantage;
the same rounds as above.
Best rounds are the 1st JSB diabolo dome head 8.44 at 99% grouping
second best JSB diabolo dome head 7.33gr at about 95%
Now the interesting part, the RWS rounds fit in the gun but will not shoot. Strange that the same
weight pellet will not shoot from a different gun. All the RWS rounds mentioned will not fire and the result is
a jammed round, i can feel the spring moving back and forth, not good for the gun I'm sure.
Does anyone else have this problem or could someone explain why this would happen as both guns are rated for
under 500fps. Scratching my head over this one guys.

some of the other stoeger rounds I tried from a sample
box did the same thing.
Regards,
old dude
