Merchants weapons

There's also a point where you have to have some common sense. Yes, the rules let you extend the range on sandcasters, but it's basically meaningless. Sandcasters function by putting a cloud of magic dust in the space between the enemy and they function like missiles that deploy chaff at a designated point. At least, that's how they worked back when they weren't time travelling into the past to block light speed weaponry that you were firing in reaction to.

You can also immediately detonate the canister to make it basically a shotgun to shred nearby personnel, whether in space or atmosphere. Even if you could design a weapon to fire improvised canister at extended range, this isn't a thing that would actually be built. You would build something actually designed to deal with boarding parties, not make your half arsed desperation action into a 3/4 arse desperation action for the very rare times it would come up.

Because for that to actually matter, first you need personnel trying to board by spacewalking while you still have a facing turret weapon manned and functioning. Which is the dictionary definition of seeing a pink unicorn.

It all depends on what exactly a caster is.

It could be a trebuchet, but I tend to think it's a mass driver.

Existing ammunition performance does indicate it could damage a spacecraft hull, if you assume double dees from a plasma or fusion man portable gun can damage a hull, or any other groundscale weapon system with double dees.

Or, potentially, any damage caused by a groundscale weapon system that manages at least ten points of damage.

Logic might discount a twenty two long rifle with maximized damage achieving that.

But, a light howitzer should manage that.

This is designed as a basic offensive round for a sandcaster. When targeting boarders, pebble canisters cause 1DD damage (Ground scale).

Limited to canonical ammunition types available, a double dee should be sufficient to punch a hole through a low armoured spacecraft hull.

My guess is, it's rather similar to a rocket propelled bunch of ball bearinged warhead, bearing down on a target.

Switch that for a missile warhead, sans guidance and propulsion, that's anywhere between a fragmentation to a bombardment effect.

For anti-barding actions where sand casters might be used, I would have thought that the leveraging the Smaller Weapons rule (HG2022 p40) would be more efficient and flexible. Depending on the weapon(s) chosen it could eliminate small craft at close range and deal very effectively with personnel. There is a small cargo overhead, but by using lighter weapons you are free of the limitation of hardpoints and firmpoints and can keep the sandcaster ready for any incoming laser fire.
