The long and short of it is.... bore sighting a new scope. I had a Zeiss scope installed and bore sighted on a Ruger #1 22 PPC at a well known fire arms store near home. During the installation there were some problems getting the rings right but we got past that OK. I should mention, I usually do this all myself but chose to have it done just because I was lazy and was also a bit short on time.
Any way, went to the range yesterday to check this scope and adjust my 17 Fire Ball to some new loads. Fire Ball worked great. Got tuned in with about 4 shots and then proceeded to fire some "play around" rounds. Best group was under 3/8 at 100. My breathing was horrible.
Then it was on to the PPC. The guy in the store said he had it bore sighted so I took his word for it. My usual results with a good bore sighting put me within 6 or so inches of target. Well, not so this time. I fired 2 shots and could not find a hole on the poster board the target face was stuck to (this at 50 yards). I thought what the heck..... Finally, after looking real hard I noticed a mark on the top of the poster board. That made impact over 1 foot (or more) high...
Rather then gauge around and feeling pretty sure the gun was shooting extremely high I moved to the bottom of the poster board and over about 6 inches off the edge and let one go. It landed at least 18" high. So, a lot of down dialing and some horz. adjustment and I was finally on.
Point being, bore sighting is just that, bore sighting. To have this much "off" setting was a bit strange for me. I got it done and the PPC is a Laser with 50 gr Berger's at 3400 fps. One rough hole three shot group. Let the barrel cool down a good bit and shot one shot.
X ring...... Thats way less than 1 minute of coyote.....
It was 60* yesterday (Jan 11) while I was shooting with a bit of rain. Today (Jan 12) as I write this its 16* and we have had freezing rain, sleet and about 2" of snow over night.
Glad I got out there yesterday.
Anyone else had a big variation in impact from bore sighting??????
