.308 rounds are great and work well with the Blaze rifle. However they do not fit in the snap loader. Pretty sure this is not intentional (or a feature) as the snap loader does not contribute to any other weapon (ingame or atm).

I wager you guys already know, but just incase:

The snap loader should no longer support the 7.62x54mmr (mosin rounds) and should support the new .308 variant.
