So many Bullets, so little bag space

[Mega Ultra Chicken]

I'm in a bit of a pickle for choosing PAs for my lowbie Newman gunner. He is both a Guntecher and Fortegunner (I may potentially go Gunmaster on him too,) meaning he would probably need more than 36 PAs. However, because I don't have premium (nor am I in any position to get it,) his space for PAs is limited. Which PAs should I go with for a gunner with two classes and little bag space to spare? ...Or would it be better to stick with one class?

What I have so far: (Putting me at 36/36)

-All elements for Rifles, Shotguns, Laser Cannons, Longbows, and Crossbows
-Boma Duranga for Grenades
-Resta
-Samegid and Sabarta
-Rabarta

[Proto07]

Rifle PAs and Shotgun PAs for sure. All six elements.

Problem is, the recommended palettes for GT and FG seem to share almost zero common PAs. Bows>Rifles in GT and (supposedly) Corssbows replace Shotguns in GT. Only Laser PAs are recommended for both.

I'm not sure exactly what playstyles you have, but here are my suggestions if you want a lot of flexibility while still keeping important bullets in your arsenal.

CROSSBOW(2):
You could probably do just fine using only Fire/Dark for crossbow (I would say the same for rifles, but I know many would disagree. They may not deal the greatest damage on all foes, but they have burn/infect which are excellent and attach on most enemies easily. Over time, you'll do equal or more damage with the burn/infect afflictions as using bullets opposite of the enemy.)

I would also use cards (all 6 elements, but that's just my preference.)

RIFLE(2):
Same as crossbow. Choose fire/dark.

SHOTGUNS(6)
Definitely keep all 6 elements, especially if you plan on using Fortegunner/Gunmaster as well.

GRENADE(1):
I personally have all elements, but if you're tight on space, using Duranga exclusively is a good choice.

LASER CANNONS(6):
All elements

BOW(6):
Not sure how often you plan on using Guntecher, but I would use remaining spots for all bow elements.

That's a total of 21 spots for bullets alone, giving you plenty of flexibility in choosing melee/spell PAs you may want.
