I am already down that that Rabbit hole, I am just unpacking the process of getting there with an eye towards filling out the bottom end of the Small arms table to my satisfaction.
The deal is that the tables in striker are based on what came before but the route and thought to get there isn't clear.
Yes there is boat-loads of detail available. My goal is the most amount of detail in the simplest terms.
Well my monster thread on the topic delved into that a bit, I guess now that I've been T5 in context I was looking for StrikerMaker.
Problem is I don't think they came up with the numbers off a universal design sequence, there are traces of it to be found but obviously abandoned and alterations to get game effects, and for the near-modern and modern small arms they just translated their interpretation of RW weapons performance.
So, probably more profitable if Striker is your destination to just look at what is there and extrapolate what you want.
For small arms, Striker is more designed for open range mini warfare, merc ops, and the small stuff is not very nuanced thanks to the very short 0-3 penetration range your average low end gun is going to have.
Most of the existing hardware sits on top of most reasonable stat ranges, perhaps a quibble with pen values and range here and there.
Melee weapons have more room for differentiation.
CT itself is more attuned to nuances for small arms.
Now I'm assuming you are talking pistol/revolver SMG and carbine. If you are talking say archaic arms, there was a JTAS article covering those for Striker. Particularly archery and gunpowder/musket era weapons.
