Given how the Goa'uld use plasma against each other, I'd imagine the shielding would be reasonably effective against it. The only established thing so far with regard to Goa'uld shielding is how concentrated the weapon's energy is. The more concentrated, the more effective.

So, it seems like their shielding is designed to counter energy weapons, what about hypervelocity kinetics, like railguns, while the darts my frigates use would be rather small (125mm diameter, probably a few inches long) they would be going very fast and so the kinetic energy would be very concentrated into a tiny area. Correct me if im wrong but it sounds like my railguns would punch through the shields with some ease, though might not do a ton of damage to the ship itself due to its size.

Blasters on the other hand im not sure, ill find an in game description and let you decide.

"Particle blasters operate on a similar principle as the railgun except they fire a magnetically contained ball of subatomic particles. No other turret class can match the sheer destructive power of particle blasters, but due to the rapid dispersion of the containment field, it also has the worst range of all turrets."
