So I'm trying to do a challenge that requires me to do 5 Screw Top Glory Kills on Possessed. Sounds easy, right? Well I can't seem to manage to figure out how to position myself correctly. It says to attack the lower right leg or the head from behind. I tried those to the best of my ability but no dice.
Any tips?

Those are quite annoying. I've never managed it from attacking the leg, so I can't comment on that, but try to melee them when their head is more upright and you have a clear shot. Aim so that the point of impact will hit the back of it's head.
Even then it's really a hit and miss... most of those glory kill challenges are like that.

This is the first Glory Kill challenge that has been an actual CHALLENGE for me. :P All of the other ones have been quite easy.

Your cross-hairs actually have to be on the specific body part (e.g., back of head) in addition to the positioning (e.g., from behind). I figured this out trying to get the "sweep the leg" achievement in the first Hell mission. This one is tricky because the undead will kind of haunch over when they're staggered, so you won't hit their head but their backs, which gives a different animation.

The rune "Dazed and Confused" helps a lot with these achievements because gives you longer to line up your glory kill.

The hell razer leg sweep one gave me a lot of issues as well. Could never reliably perform that glory kill and usually run out of hell razers before I can pull it off.

That one was easy once I figured out what leg to shoot. Also: The Heavy Assault Rifle is so good in helping you get glory kills. ^_^

If you run out of [insert monster here] to perform the glory kill on, simply reset to a checkpoint and try again. You can do this as often as you like until you reach the number of required actions to get the achievement.

This also works for weapon mastery. For example, to get the precision gauss gun mastery, you have to headshot 5 Hell knights. There's a part in the last mission where a Hell knight is on a bridge off in the distance, but won't attack you (or even move around) until you drop down into the area, so I just shot him in the face from a safe distance, and then reloaded from the checkpoint and did that 4 more times.

Another example is the rocket launcher's lock-on mod, which requires 5 summoner kills. Find a fight that has a summoner (e.g., the Argent Facility, or just before you get into the based of the Argent Tower), kill it, reload from the checkpoint, and repeat.

Yeah, I noticed that. But I decided to enjoy the game my first run rather than farming out upgrades. Besides most of the mission challenges are pretty easy to do without much effort anyway.
Though I do find it a bit silly that the more you die, the more likely you are to complete the mission and mastery challenges.

try aiming above the back of thier heads when they stand upright and use a single shotty against them weak enough to damge them enough but not kill them

The Heavy Assault Rifle is better in my experience.

[Underqualified Gunman]

upgraded pistol works as well but maybe due to me keeping about 5 feet at all times from anything that moves

[Ostarolon]

The most consistent target I've found is the right calf - the Doom marine stomps down on the calf, causing the Possessed to kneel, and then twists the head.

Targeting the head only works if they happen to stagger upright (or something). It's much harder to time/target.

[Feasting]

When staggered, stand behind them and target the floor somewhere near the right foot.

[icon_of_sin]

I have found that targeting the right leg is easier than the head because it is always visible from behind, moves less and the correct attack is more likely to be triggered.

I always stunned the enemy first (a singe melee from the front will do)
Im not sure if a stun before the actual attempt is needed or not

the only 2 challenges that were kinda dumb, was the Kill-a-Lost-Soul-using-another-Lost-Soul one (even that was somewhat easy using a BFG round), and there's another towards the end of the game where you have to perform a Death-from-Above fatality on a Baron-of-Hell
