Just use Autoloader until fix. It fixes all current bugged issues with concord cannons, and besides, all other experimantal for cannons nowhere as good, as Autoloader does increase from 3x3 shots to 4x3 per reload, by time 3th burst is fired. That does increased DPS quite a bit, and if stacked by factor 5 or 6, thats one of most insane pure kinetic dps around.
As for it being semi-auto (rather automatic), it does not diminish its devastation potential any bit.
Its semi-auto for me. If I press trigger and hold, it fires only once (3 shot burst, thats it). I didnt tried anything else than stock or OC, but both was semi-auto for me.
5% more dmg on SRB vs OC, is not worth cutting range by 50%, not with this weapon, IMO. Lemme explain why;
Its quite accurate and it works nearly to its max range, as there is no dmg falloff at all in that weapon, becasue even if not gonna hit modules reliably past 2km, its still gonna hit enemy ship regardless (all medium to large sized ships), in mid range to its maximum range. But there is catch to it:
Well, I could destroy modules of big ship cmdrs (thanks to oversized modules hitboxes), with no problems even at its max range of 3,5 km, but the mentioned catch is that, I used 6 of them at same time (on p2), so some shots always hit its mark, even at max distance (most of them, actually);
This setup is like long range "high caliber shotgun" that does shoot 1300 m/s high breach chance projectiles, as with atleast 6 of OC Concord cannons, each trigger pull, causes fire 18 cannon shells. 21 dmg x 18 = 378 dmg per trigger pull - autoloader allows to shoot 4 times per reload at max fire rate (4sec reload duration) so dmg per mag is about 1512(!) dmg of pure kinetic maddness... thats it, if all 72 projectiles hits its mark, but in close to mid range, this is not a problem at all, given that chaff is so rarely used these days by tons of cmdrs
I'd say stacked OC concord's kind are superior to pacif frags even, far as pure kinetic dps goes, due of higher velocity and range, higher AP, and better breach chance and of course by ease of use, being gimballed.... but with atleast 6 of them.
Of course such dmg can be hindered by kinetic resistances by a lot and hull hardness as well (even then still does quite dmg), but for an any "unprepared" bulid that skiped hull day or does not had decent kinetic resists, its gonna be bad news indeed, and some cmdrs already found it hard way
Thats why I meant if use autoloader, it gets more crazy if more cannons are used at same time, and this weapon takes it to another level.
