New rem 870 shooting low with new winchester blindsides

[jethro66]

Does anybody have their 870 shooting low? I shoot 3 rounds at 35 yards and
only 5 pellets hit the bull.30 pellets are in the kill zone with factory mod choke.
Would a true glow sight improve my pattern or just try another brand?Would
true glow sites help or just aim higher??

Maybe it's your choke tube. Try the Improved Cylinder, that blindside shot is packed in pretty tight and the constriction of the MOD tube may be causing the shot load to blow to hell once it clears the muzzle.

Gun fit. try with normal steel or lead. they will do the same. In order of importance. Fit, choke, load..... then work on stuff moving...
