Remove the bolt, look down the bore and center the target in your bore, adjust elevation and windage while not moving your rifle. Go to work! Works every time.
I love the ones the gun store folks mount that have the turrets or caps almost touching the rings on one end or the other. Haven't gotten one with the vertical on the side though. YetI think most of us will have funny stories. My first rifle, was used and had a scope. Second rifle, new, bought scope, so called expert mounted for me. Went to range, figured out he had it 90 degrees off, L-R was elevations and vise versa. Never let anyone mount a scope for me since.
Seen that! Sheriff did it on a brand new rifle!I had a buddy who forgot to take the boresighter out of the barrel.
Cost him a trip to the gunsmith to cut 2" off the muzzle because of a bulge.
Just not worth it.
As I said earlier, with the Bushnell Bore Sighter, I can switch scopes on a rifle and hit my 20" gong at 500 yards on the first shot - that isn't going to happen with the "look through the bore" method (I have tried that) but recording your shot with a phone on your spotter typically results in only one wasted bullet.Yep, I had those and used them in the past, they are OK.
But once I got good at sighting by looking through the bore at 30-50 meters (near zero), then just shooting at far zero (the actual zeroing intended, in my case at 100 meters), I can do that with 3 shots, way faster (in minutes), for any caliber, anywhere, with no need of extra gear.
I sighted for many friends, and taught them, so they can replicate whenever and wherever they want.
With a bolt action, I just remove the bolt, put the gun in a vice (with wood or carboard to protect it), shine a light through the bore at a dark wall about 20' away, then line up the scope about and 1" high. I put a yellow sticky on the wall where the light hits.I've reached the point where I believe a bore sighter is needed. I have no experience with any of them
Can any member offer a brand/model based on actual experience?
Thx in advance for any suggestions.
