>If I zero 7.62x51 with a 20 in barrel at two-hundred metres, should the bullet still be rising at three-hundred?
>I have another armalite with a Huldra MkIV upper in 5.45x39 and a 16 in barrle. Where should I zero it?
This would be beyond my area of expertise. Generally a 200m zero is good for most intermediate calibers, but I do not know the common practice.
>Is hitting a bit wider than the black torso of the standard sillhoutte with irons bad?
Yes, generally it should fall within a 12" circle at 300m. Luckily, this just means you need more trigger time. Unless your weapon is defective or out-of-spec, this is something you should be able to hit even with irons.
>What red dot might you recommend for less than 200 dollars to be used up to 150m?
Sig makes some good stuff. Just bought a Romeo 7. It resembles the comp M4 from aimpoint, which are my preferred optics when it comes to red dots. I'll let you know in a few months, since I do beat up my stuff a bit.
>I read on a thread about PSA's rifles that their barrels were the loosest this user had ever seen. Maybe they meant the barrel nut? I'm a new owner.
That's odd. PSA generallly isn't too bad, but again, I've never owned one myself. It doesn't hurt to have a torque wrench and tools to double check the torque specs, but if it isn't giving you any trouble, then this might not be a priority. Other than my own builds, I've never had to tighten a barrel nut on a pre-built rifle.
>The rifle had less than a half-inch horizontal spread but one outlier at less than two inches away horizontally at three hundred meters.
This looks pretty good.
>It was probably with a foot of vertical spread.
This looks like you might need to work on your fundamentals. The rifle sounds fine so far. Focus on gaining a steady position and breathing. Relax and shoot at your normal breathing pause. It's easier if you take the shot on the exhale pause. Do not hold your breath, this makes it worse.
>I hope it's okay to ask so much even when I can find the answers elsewhere. I just can't find the answers each time that I search, don't want a dead thread, and don't want other people missing out on some good answers
We're all here to help each other, comrade. Relax.
I would recommend you look into magnified optics for your rifle, though, and save up a bit. A 7.62NATO rifle can provide excellent support at intermediate ranges up to 600m. Get good at what you do and you'll be hitting there in no time. I would also advice you take stress shoots to learn your breathing better once you get proficient. Go take a run, or do 50 push-up, burpees, etc. This is good for testing your fundamentals as well as building on them. If you can shoot like this, you can shoot in almost any circumstance.
