Sounds like a 50 yard zero on the 250 setting and then check dope on steel out to 300 is the answer.
Ill play around with it a bit

250m is a good range for a battlesight zero. With 7.62X51, you should be able to aim directly at the vital zone of a target, or hold over or under a bit, and hit it up to that range and somewhat beyond, and most engagements with man or beast will be within 300m or so.
Not sure about the 150m setting. Probably more convenient for zeroing, though, if you're using a barrel/load combination that has a trajectory corresponding to that for which the sights were designed (NATO ball/21" barrel). Sight in at 150; while verification is always preferred, under those circumstances it should be good, or at least close enough, at the 250m setting/range. Keep it on 250 for actual use.

I would zero for 250m.
At 21-22 yards, POI should be almost the same as POA compared to 250m (making it a good range to get a preliminary zero/get in the ballpark). At 50 yards, POI should be about 2" above POA for a 250m zero. A 250m-zeroed rifle at 300 yards should hit a bit more than 2.5" below POA. Holdover should remain reasonable out to perhaps 330 yards or a bit more (which is a bit over 300m). Drop will be over 9" at 350 yards. Drop rate increases rapidly past that range. Highest POI relative to POA would be at 145-160 yards or so; about 5.2".
A 50-yard zero would hit 14.5" low at 300 yards. At 200 it would more reasonable, being close to 3.5". POI will be the same as POA at 127-128 yards. Less than 1/2" high at 100.
Data is based on DAG-manufactured NATO ball (M80-style bullet) out of a 16.25" barrel.
You'll get the most out of your rifle, I think, by actually zeroing at 250m, or something close to that, and then seeing where POI is relative to POA at 150m on that setting (just so you know), although the 250m setting will be useful for pretty much the whole of your usable range.
300-yard zero should still have reasonable hold-overs out to 350-360 yards or so, if you wanted to stick to yards. About 6 1/4" low at 350. Highest point would be a POI about 6.6" above POA in the 155-175 yard range or so. I wouldn't try zeroing at a longer range than that with that sight.
Also, take note that the sight adjustments for zeroing are based on meters. The windage screws move the sight over 1cm at 100m per click. I believe the 16-click-per-rotation front sights are the same in this regard. 12-click ones exist as well, IIRC, which I suppose would do 12.5mm at 100m. Front sight posts also come in five different heights. If you can't get zeroed with a particular post, or you are at or near one extreme or the other, switch to the next highest or lowest sight as appropriate. Repeat as necessary.
