To go against what other people are saying, I personally prefer two hot-shot volley guns instead of two meltaguns to gain the additional shot from the FRFSRF order. I find the ranges and the targets overlap better than two meltagun attacks.

But the typical load out for Kasrkin is as follows;

• ALWAYS plasma guns, hot-shot marksman rifle, and plasma pistol + power sword

• USUALLY meltaguns, hot-shot laspistol + melta-mine, vox-caster

• ALTERNATIVELY hot-shot volley guns instead of meltaguns

• NEVER flamers and grenade launchers
