When you find the right box of ammo you should have 1 in 40 or less jam on you.....The Rem Gold 36gr at 1280
has yet to jam in my auto.
Here is a picture of some that work for me.......notice the heavy crimps on the three on the right!!
I did not notice this til today with my close up picture and lighting.
The cheap Fed Amer. Eagle far left jambs in auto and also will not eject in my win pump............the
rest are ok and notice the different lengths and tip styles.
The cci stinger (far right) with the long case, shot better groups than the Rem 1500fps yellow jacket .
