Bore site kit - AimShot Universal Laser Boresight Rifle Kit

The kit is useful for what I need yet I expected each cartridge bore site would be individual like I had to order separately that didn't come with the kit from the same company.
I think there are different opinions for the most widely used calibers according to competition and just comfortable with a few calibers for bore sites. Research should be made with ammunition sold as opposed to which firearm is sold for bore site kits. That's only my opinion.
Maybe having the customer order the calibers of their choice would be more expensive but they get what they want and not what they don't use.
