teppou,
Gas gunners don't have the luxury of loading all the way to the lands like bolt gunners. Unless you are prepared to hand-feed rounds into the chamber like long range Service Rifle matches, which of course defeats the purpose of a semi-auto.
Here is a list of OAL's bullets would have to be for a 2-thou jump to lands in a Lilja chamber. In all cases the mag prevents this from happening. Jumps are always longer in a gas gun which means incremental differences in OAL are going to be less noticeable and less meaningful. I load to the max steel mags will permit, 58mm/2.283" and leave it at that.

Happy to try different bullets and powders where differences are obvious and significant but I save COAL tuning for bolt guns where you can see differences, where subtle differences are more meaningful, and any cost in velocity is insignificant. At some stage you have to accept the limitations of the gun you are loading for and honestly question whether subtle changes from OAL are going to make a meaningful difference in how the gun is used - unless you just like to tinker.
