The 056 was the original, the Super had a piston that was 2mm larger in diameter and an slight carburetor change. The Magnum had the same piston as the Super, but had a carburetor and ignition change, The one you did not ask about was the Magnum II (of which only 70 some were made) had a major carb change, a muffler change and an ignition change. It could be further modified in the muffler.
With Stihl most Super models have a piston diameter that is 2 mm larger than the other version of the same model. The Super is still an AV otherwise as that stands for anti-vibration, which means that it usually has four shock mount buffers between the engine and handle

I have written in my Stihl 051 AV electronic Owner\'s manual that its horsepower is 5.8 hp at 7,000 rpm. I don\'t know if that is true for a Stihl 051 super. I have never heard of a Stihl 051 super.
The difference is in the motor size.The 034AV is 56.5cc (cubic centimeters) and the 034 Super is 61.5 cc (cubic centimeters). The 034 Super has a slightly larger motor, and therefore it presumably also has greater speed and power.
51.4cc

There is no .338 Lapua Super Magnum. There is a .338 Lapua Magnum which is considered a member of "Super Magnum family". .338 LM uses several different bullet types and drop will depend on bullet type and weight.
