One of the guys in the picture at the 2,000 yd. range was shooting his 338 which is a real kicker. They quit shooting their rifles and shot mine. It was easier to hit the gongs from 200 yds. all the way out to 1,200 and back to 200 yds. just by turning the custom turret to the yardage.
It sounds like you want to find out how it will stand up to the big kickers which I do not know because I shoot a 6mm Norma BR with 105 gr. Berger VLDs out of a 14+ pound rifle. The guy that hit my car from behind totaled his car and the impact did not affect the PSE at all.
Maybe when they are back delivering the PSTs with the tighter turrets and better QC of the vertical on the reticle someone will put one on a 50 BMG and we will find out.
Personally I have not used a NF or other expensive scopes.
As for shooting a group at a distance and turning the turret in between shots and then back to see if it will track perfectly I think it would have to to be able to go from 200 to 1,200 and back to 200 yds. in 100 yd. changes. Example: shot at 200 then 300 then 400 and so forth up to 1,200 and then back down to 200 yds.

PS: I am very happy with this scope. Oh I have had to adjust the windage turret at long distances to move the impact to the right and left and the clicks seem to be perfect.
