Yup, I've used them out of my 26" Remy at 1000yds. I was achieving the same results (c. 0.75 - 0.8 moa) with the 175 TOTMs set at AICS magazine length with a massive jump as I was with with 185 Juggs that were optimised for single feed. The cost, and mainly availability or rather lack of, meant I stuck with the Juggs though.
As an aside, I recently tested Nosler 175 RDFs set to AICS mag length at 100yds with the same sort of groups as the 175 TOTMs using N140 although the load was caning the primer pocket so they MAY have the same potential at 1000 yds but until I get a chance to try them on the range I can't confirm that potential (I ran N150 through QuickLoadbut the velocity at 1000 wasn't predicted to be fast enough to record on the ShotMarker system). I went back and pressure tested using RS52 which I think will be a better powder option but until the ranges open again next year I won't know for certain if I can find a load that works when the cartridge is built to mag length. What drew me to the RDFs was actually the price because at what I picked them up for I would have been happy to use them for plinking, McQueens or 1000 yd competitions (if I got them working!). However, and it's a massive however, the price has spiked alarmingly since I got my 1st box back in September with £69/100 quoted on 1 suppliers website recently although I did manage to get a box at £53. The RFD told me they were likely to be £59/100 the next time IF he could actually source any.
