Effect of Split chamber is to have a percentage chance of producing the effect of firing 2 rounds with only expending a single round of ammunition. Each round fired has the listed chance of producing a 'magical' second round.

That means it works perfectly fine on a single fire weapon as it has no relationship to ammo expenditure.

You'll want to max it though - and watch the effect on your damage output.... enjoy
