what are the max lode for bother caliber (top speed)

You need to give more details on what your looking for. There are many different options in both those calibers; bullet weights, powders, barrel lengths, etc.

A couple of books you might invest a litte money into, a Nosler #6 and a Webster dictionary. lol

luisss...............Regardless of what anyone posts here as max load suggestions and bullet speeds for either cartridge, it will pertain only to their individual rifles.

You take whatever info is offered here or from any reloading manual, start a few grains lower and then work up a 1/2 grain at a time until small pressure signs are seen, which will then determine accurately the max loadings that YOUR particular rifles will accept.

As soon as very small pressure signs are seen or detected, back off a 1/2 grain and consider that charge as maximum for your rifle. Then chrony that charge to determine your speeds and live with the results you get.
