I would think artillery are the worst gun for mjd sniping because you're still fighting in falloff.

Solution: Don't fit a MJD, just don't fit like a ****** and die to world's collide...

the only ammo you need if phased plasma, emp, and fusion. Don't bother with that sabot nonsense.

What he said.

What is the better choice when Eve-Survival recommends Kin damage? The projectile chart shows Sabot has the best Kin damage (2 exp, 6 kin) with 1.2x tracking bonus and 0 range bonus.

Use a maelstrom, but you should not passive tank it like the fit earlier, and you should not rig it with defense screens, you'll just be using two mission-specific hardeners. This is the fit I currently fly with..

Maelstrom is a brawler. If you are going to use it in a mission, you mine as well fit it with 800 ACs and active tank it as some of the above Maestrom fits, but add a Heavy Cap booster as it is insane to get a Maelstrom cap stable. The MJD really isn't needed, but an AB would be nice. If you like the Tempest and want to upgrade in the future, I would recommend a similar setup on a Macherial.

Yes, very true.
Also, OP asked for Sniper Fits.

I never group artillery, the overkill potential is so huge, and the rof so slow. Also I always fit a Large Projectile Burst Aerator to arty fits, makes the cycle time ~5% shorter, and any RoF bonus is just nice with them sloooow arty.

and some one else mentioned it but for sure a Machariel is a huge upgrade.

FYI, I've done Worlds Collide in a buffer-fit, MWD-fit, sniper fit Tornado. It performs beautifully if you know what you are doing, and you don't go up against missile users.

In my opinion, a MJD is awkward to use (tends to waste time), and best used with short-range weapons. With long range artillery, you don't need a MJD; an AB or MWD is fine.
