Cartridge Laser Bore Sighter

I have a Remmington 700 chambered for 7.62x51 (.30. I would like to zero this rifle with a cartridge laser bore sighter but can't find this caliber available. Would a .243 or 7mm-08 cartridge laser chamber into a 7.62x51 chamber?

You can also use a 30-06, .30Carbine or any other 308 caliber sighter.

Sorry, just reread your question. I thought you were referring to sighters that slip into the muzzle. As for the chamber-type I would assume that as long as they don't fit into the cartridge neck they would work if they're based on the .308 case. Again, I apologize for the misunderstanding.

Well, you can't actually "zero" a rifle with a bore sighter, but you can align the scope and sights that way. Once you get aligned, you have to go to the range and zero your rifle/scope combination. The idea is that you should be on paper once your aligned.

This is correct, but once you've zeroed your rifle on the range, you can use a bore sighter to determine where your actual zero is relative to the boresighter's laser or reticle.

You can then check in the field whether or not your rifle has held zero during travel, without having to fire a game-spooking test shot. (Not absolutely perfect, but pretty darn close.)

Of course, this assumes your rifle doesn't have a wandering zero to begin with due to stock warpage, bad 'scope or mounts, radical temperature difference, etc.

Always thought a laser was good for initial setup but the true "true" comes when you fire it.
