Core lokt are the best overall non premium ammunition. There is, with normal cartridges like the two you mentioned, no real need to upgrade to partition or bonded when hunting deer or other light game.
With the .243, I would personally prefer to move up to a speer hot core "bonded" bullet to enhance penetration, and in 30 caliber, I'd prefer a polymer tip to open the wound channel quicker, but that is all in the handloading arena around here. Factory ammo in those types aren't ordinarily available. So, my purchases would be core lokt.
If core lokt give you acceptable accuracy, and they should, get them, and know that you are holding at least a 9 out of 10 in cartridge performance.
As was said, there are plusses to being sighted in and ready to go with ammunition that can be picked up in thousands of locations around the world, like corelokt. In some states, you can probably find 150 grain remington 30-06 in more locations than you can find condoms.
