This is a sight I am fooling with at the present moment on a Youth Model Remington 870.
I am using the PXS 1000 Easy hit. Works using ambient light (not real good in a dark turkey blind), can be adjusted for windage and elevation, and it clamps onto your vent rib.
I used a Bushnell Lazer to dial it in a bit before I went to shoot.
Here is the red lazer the best I could do.
Started at 15 yards using 7.5 Trap loads.
My first shot I was not impressed with the pattern at all and then I found I had not replaced the Hasting Extended Choke tube! Dummy!
While it isn't bad it is not as tight as I thought it should be.
Put my choke back in and adjusted but went too far down. I like to use the Waddles as my Aim Point.
Then I went back half the turns on the back hex screw to bring it back up a bit,
My third shot
Pretty happy with that so now I tried a Winchester Supreme 3" #5 Turkey Load,
And real happy with that pattern. But I still need to run tests at 20, 30, 40, & 50 to determine my lethal range. I hope to get to that this weekend.
I bought this youth model for my grandkids but just might use it myself. Very light and will be easy to carry as a back up if I take the Xbow.
