I don't know about Swaro's ballistic programs but I see a lot that don't take into account spin drift, which is significant at really long ranges. The Sig Kilo 2400 takes into account spin drift as well as aerodynamic jump.

Provided they got their math right! The physics are the same.

As pointed out, some programs might allow you to enter more estoric variables.

But the limiting factor of any ballistics program will be the accuracy of the data you enter.

Besides altitude and temperature, factors such as humidity and barometric pressure can also impact projectile flight.

Fortunately, few humans can shoot accurately enough to make these variations felt at practical shooting distances.

Ballistics software is differentiated, other than the User Interface (UI) and features, by the core algorithm, which is usually called the "ballistics engine"

While about 95% of the programs out there rely on the same engine, called POINT MASS, there are still some differences in the way the software developer coded the algorithm, take into account that only a handful are really backed by real ballisticians...most are just programmers (good or bad) that simply downloaded a copy and tried their best, but not really understanding what they are doing.

On the other hand, companies such as Swaroski, Leica, etc. offer a basic stripped-down software, not really good and nobody serious about LR/ELR hunting or shooting use them, they are not really accurate.

On accuracy the key factor here is the sonic region the projectile is traversing thru...inside the supersonic zone (provided input data is right) most will yield a good prediction, it's the transonic zone where you can tell apart the quality and robustness of the engine.

It's a very long and technical subjet to delve into all the details, but don't get fooled by appearances alone, it's what lies under the hood what separate the men from the boys
