MK103 currently has 2 actually useful for Air-to-Air belts:
- HVAP due to best ballistics (the damage is… well, sometimes it works, sometimes it doesn’t).
- Air due to having shells that can kinda rival Shvak 20mm FI-T with 6g of TNT equivalent hitting power.
Problem?
While air belt outranges Shvak a bit, while rivaling its damage capability, it is 3xM-geschoss, 1xSAPHEIT.
The latter shell deals basically as much damage as 7.62mm AP bullet, unless it hits something thick, then it explodes with an energy of a firecracker, and spall acts like confetti. Best case scenario, you get similar damage to 13mm MG HE bullet with 1,5g of TNT.
Worst case scenario - no damage at all.
While in the past MK103 indeed was “the gun” that was just out-damaging everyone, nowadays it’s no longer true.
Shvak deals way more damage per second due to higher ROF. MK103 due to low ROF oftentimes lands 1 shell on target, and if it strikes f.e. Yak-3 wingtip even with M-geschoss, it could have as well missed entirely, as Yak-3 flies without wingtip better than Fw 190 intact.
US AN/M2 can do exactly what Mk103 does with way better ROF. Range is basically the same (the difference as can be seen below is largely inconsequential below 1200m, GL hitting people from further away) but US cannon has better belt composition.
So, with MK103 having no real advantage over 20mm, outside a bit shorter flight time on longer-range shots, maybe we should reconsider making the Air Belt 100% HEI-T (M-geschoss with tracer)?
Right now it’s ridiculously annoying. I fire at P-47 in a head on - hit. I fire at him again, trying to help my teammate “hit”. I’m fairly certain it was SAPHEI-T? But maybe I just got gaijined (happens WAY more often than you guys think with high caliber low ROF guns)? No idea, no way to tell!
With full HEI-T belt MK103 at least will be more reliable. Or easier to bug report. Right now there’s plausible deniability - sorry, you hit him with potato shell, try again!
Easy to say where EVERY plane with Mk103 flies like a goddamn brick. Which further exarcerbates the problem.
What do you guys think?
