I've got a sfp 6-24x50 PST on a custom M700 in 223 AI; 26" Krieger 1:7tw sendero contour, McM A5 stock, EGW 20 MOA sloped base, TPS TSR rings. Took the little rig out to a precision rifle match just for $hits & giggles, and to get more cases fireformed. I'm running Berger 90VLDs at 2820fps; used Litz's PMS to print out come-ups to the 1400yds we shoot at this match. Made it to 1300yds OK, but ran out of elevation at 53.25 MOA while dialing up for 1400 - needed 58.88, according to the print-out. Used the 5 MOA hashmark on the EBR-1 reticle for hold-over, and got the hit. 90s went subsonic at 1260 according to Litz, but obviously stayed stable, as hits on 1300 & 1400yd plates were good, round impacts, with no indication of coning or tumbling. Whatever - ran the elevation knob back down to the zero stop before casing the rifle after the LR stage, then put 7.5 MOA back on it to shoot the mover at 443yds. Elevation was dead on. That's about all I'd ask out of a scope in this price range.
I've been shooting it on this rifle since last summer, and haven't had any sort of issue with it. After I'd shot it for awhile, I got another one of these scopes NIB out of the same batch - will have to put it on something with a little more recoil to see how it stands up. Getting ready to do a 280 AI bbl for a LA M700 in a bare-bones McM A5 stock; finished rig will probably weigh just under 13lbs. If the 2nd PST will stand up to the recoil of that rifle, I'll be sure to get back online and bang the drum a bit more for the PSTs. As it is, I'm very pleased with the 1st one - no, the glass isn't quite as good as a Sightron SIII, but then the PSTs cost me a couple hundred bucks less than a 6-24x50 SIII LRMOA, and the difference in glass is only really apparent when you're trying to resolve .22 cal splashes on steel while the targets are in shadows.
