earlier today I had a chance to use our Wheeler Laser Bore Sighter for the first time ....
Weather : sunny sky, target in full sun,
distance : 25 yards
firearms on which it was used :
Henry 22LR
Ruger 10-22 22LR
Henry BBS 357 Mag
Henry BBS 44 Mag
Ruger Redhawk 44Mag
results :
all 4 rifles are equipped with magnification, crosshair scopes .... could
NOT see the green laser dot at 25 yards with unaided vision .... green laser dot clearly seen through each of the 4 rifle scopes .... adjusted the crosshairs on all 4 rifles to where the dot was 1" high at 25 yards .... subsequent live firing of the 22's and 357 confirmed that with the crosshairs dead center, the bullets hit very close to 1" high .... the minor adjustments required bring the impact point to 1" high were easily and quickly made .... sighting the 44 Mag turned out to be an entirely different animal .... with the same bore sighting process, the live firing mystified me at first .... our targets were 6" paper plates with stick-on 1" dots .... the first few shots didn't hit the plate and I had no clue where they were actually hitting ..
.. the first thing I checked was the scope to see if it was loose, nope, seemed fine .... I reinstalled the laser bore sight and the impact point wasn't the same ..
.. corrected the crosshairs and fired another test shot .... nowhere on the 6" plate ..
.. made the decision to determine if it was hitting high or low .... to do so I held the crosshairs on the bottom of the 6" plate, no bullet hole .... the held them roughly 4" below the bottom of the plate, finally, a bullet hole dead on the vertical line but a couple of inches down from the top of the place .... in short, left-right adjustment was perfect .... the up-down adjustment was around 9" high .... cranked the crosshairs down, now hits 1" high at 25 yards .... close to 100 rounds followed confirmed that she's sighted in where it should be
have spent considerable time giving thought to the why ? .... my belief is I didn't take the care to try and place the center of the bore sight in the center of the much larger 44 cal opening .... with a 22 there isn't much room for error but there is with a large bore .... in short, the sighter worked and I've learned a good lesson about using it with a big bore .... all in all, well pleased
with the Redhawk, I couldn't see the green dot when looking through the Aimpoint which has no magnification .... I believe I can make it work if I try it again with much dimmer lighting
