Ordered some Crosman box .177 heavies recently. Wanted to try them in my Diana 54, one of the few pellets I hadn't tried. Decided to weigh a few, they were consistent. Thought I would also drop a few thru my PelletGage. Sadly, they would not even fit thru the 4.55mm hole? They have a flashing, 2 seams 180° on either side of them. Shot a few, they loaded with slight resistance, they did not group at any distance.
Suppose I could send them back, or try and find another rifle that might like them. Not impressed.
Beware of Die "M" made April 2017
Anyone else had these oversize issues?
If they are showing flashing I would give Crosman a call and inform them. They will probably replace them.
