Thread: Bore Sighters - any good?

Just take the bolt out and bore sight. Easier and more accurate.

Essentially they are useless as you have found plus I don't like the idea of pushing mandrels into the end of my barrels even though some may be non metallic. I believe the cartridge case laser ones are even more crappy.
I can guarantee a hit on A4 paper @ 100yd using the @gadgetman method. I bore sight using a power pole insulator in the paddock next to me, aprox 80 yards away. Or sometimes the tip of a strainer post on my boundary. I have also heard of a method of drilling out the flash hole on a fired case and sighting thru that - have not tried myself.

I spent $100 or so on a tapered red dot laser one that you insert into the end of the barrel. It has different plastic fittings for various bore sizes. It was a bit fidly and worked ok but I wouldn't waste my money again, it's just as easy to bore site looking straight down the barrel as suggested by gadgetman. I now use the laser sight to play with the cats as I hardly ever need to bore site once the rifle is sighted in. Once your on the target at 25m or so it's reasonably straight forward to site in from there.
