Not too much wrong here, other than I'd venture the opinion that 1gr increments are bit steep, even for a larger case like the .264 Win Mag. 1/2 gr steps are plenty.
Some people pick a powder from the loading manual w/ the bullet they choose to work w/, start at the manuals recommend minimum load and start working their way up. Not entirely a bad idea, and probably the safest overall. Just may go thru a butt-load of components getting from the min load to what ever maximum is in your gun (may be more than what the manual shows).
Another one I use a lot, and the normal disclaimer here, I'm not necessarily saying its a good idea, just that it is what I do. I pick a powder from the manual for the bullet I have on hand, see what the max listed load is, then back down about a grain to a grain and a half and start there, working up in 0.3gr increments, up to and perhaps a little over the listed max, depending on the gun. Your mileage may vary (YMMV).
Finally, try doing a search on 'OCW' or Optimal Charge Weight on the forums at www.accuratereloading.com, www.snipershide.com,
among others (can't remember if the guy has a thread here on it). Probably a bit into the 'advanced' load development, but it might float your boat anyway.
