Rather than "case length" I believe you mean cartridge overall length abbreviated COAL. The answer is yes your COAL would probably be similar.
The way I set up dies for Encores and Contenders is to start with the bullet deliberately seated too long. I progressively screw the bullet seating stem down in small increments thus seating the bullet deeper in the case until the length is such that the action will easily snap shut with the cartridge in the chamber. The resulting COAL will be such that the bullet is just off the lands.
Also, bear in mind that different cases, different powder lots and different primers can make a difference in cartridge pressure. Start low and work up. The load where the best accuracy is obtained is the one to use. Typically, if you start a load low, as the powder charge is increased, the groups will get smaller to a point and then start to widen out again. Stop where they're the smallest.
