Im just looking for the COL for a SGK in .224 dia 65grain.

The Sierra manual lists it at the max, 2.260".

Just something to think about when discussing COAL. The reason it's listed in published load data to to qualify the conditions under which the data was developed. Many times it is shorter than the SAAMI COAL. It has nothing do do with how the round will function, feed and shoot in your gun. I mention this because at some point a lot of folks look a hand loading data as a recipe for producing ammunition and not as guidance in load development.

Generally, in rounds which do not need to be crimped, bullets should be seated out as far as possible without it engaging the rifling when chambered and still fitting in and feeding reliably from the magazine. This leaves maximum space in the case for powder. At this point load development should begin. COAL in rounds which need crimping is controlled, more or less, by the location of the cannelure on the bullet itself.
