Bullet Flurry

As you ready your firearm the barrel glows with a ferocious red glare, and you fire a quick volley of 3 magic induced bullets who leave behind a trail of red. Make 3 ranged spell attacks, for each hit upon your target, deal 1d6 piercing damage with a pistol, and 1d8 for any other gun. You may only use this spell when you have at least 3 ammunition, it expends the bullets that are used. For every spell slot above 1st, add an extra bullet.
