Ranged Spellstrike and firearms

[kurohyou]

So, with the Heroes of the Streets player companion a bit ago, we now have the Eldritch Archer magus archetype which gives us ranged spellstrike as a 2nd level class ability. The ability spells out pretty clearly, that just like with standard spellstrike, you can only deliver one charge of a spell with each attack. What about firearms though? Specifically firearms like the Dragon Pistol.

Dragon Pistol:

Like a miniature blunderbuss, the dragon pistol fires pellets or a bullet from its flared barrel.

The dragon pistol fires in a 15-foot cone when firing pellets, and has a 10-foot range increment when firing a bullet. For ammunition, a dragon pistol uses a bullet or group of pellets and a single dose of black powder, or else a single alchemical cartridge (with either bullets or pellets) as ammunition.

If I somehow have a dragon pistol as my arcane bond weapon and the reach spellstrike arcana, can I spellstrike through it using pellets and hit everything in the cone with shocking grasp?

Probably use the volley rules, where your spell only affects one target in the area.

Thank you James, I'll look those up.
