Might not be the best category to ask in, but just throwing this out there. Thinking about picking up a boresighter here in the next week or so. With the price of ammoI want to atleast start close at 100 yrds...who makes a decent boresighter for like $50-100? Is lazer better than mechanical?

Would like to find one that will work on both my rifles and scoped slug guns...
