338-06 speeds.

52 grains of Imr 4320 with a nosler 200 gr ct has a book speed of 2690. This is of course out of a 24" barrel. Well I loaded the same load in mine that sports a 26" barrel. My question is how much of a velocity increase should I see with the longer barrel? Because the drop chart im putting tigether is showing something that is so high I don't want to say it publicly until I can verify on a chrono.

According to Quick Load your load with 24" gives 2610 fps and increasing to 26" barrel speeds up to 2650 fps. You may have room to increase (incrementally and slowly for safety) For example 54 gr to get 2750 fps.
