Question by Andrew Maxwell. Uploaded on December 09, 2012
I only use a bore sighter in an action that does not allow me to look through the bore to the target. I find my old eyes are still better.
I have a Bushnell bore sighter that I have had for probably 20 years. I can't explain it but for no apparant reason on one gun it may put me 1 inch from the bullseye and the next gun it may put me 1 foot or more from the bullseye. I have tried everything and haven't come up with a logical explanation why yet. I still use it to try to same ammo. I start out at the 25 yard line anyway so it usually gets me close enough to start. When I put my shot 1 inch low at 25 yards my shots at 100 will usually be right on the money with most rifles or at least very close.
A bore sight (collumnator I think?) is designed to put you on the paper at 25 yards and is only as good as the scope and rifle you use it on.
I've got an el cheapo Tasco I got a Wally World for around $10. It does "ok".
I have a bolt .270 I mounted a Leupold VX-I on. One shot at the 25 yard target was dead on. Three at 100 yds was a clover leaf 1 1/2 inches high. That was 1977 and I have only made minor adjustments (1 or 2 clicks) over the years.
I mounted a Bushnell on a Revelation .22LR. The bore sighter said dead on. It wasn't even on the paper at 12 1/2 yards!!
do not buy one they are crap use your eye and go sight it in without theyre crap
