I could not get my SAUM to shoot the 175's very well. I didn't keep after it very long because the 180 ELDM and 168 ABLR both shot great right out of the gate. I Tried h4831sc and imr7977 and hit pressure early with a lot of generally erratic behavior mixed into the short test run I did. I think I've read somewhere that the ELDX is maximally sized and fares better in looser bores, who knows. I also was limited to 3" OAL so their insane length played a role I'm sure. They're something like a tenth longer than the 180. Curious to hear how you fare.
I highly recommend the 180 ELD if you have better luck finding it than the 162. You'll be running it better than I am in that Tikka action. Both it and the accubond LR tuned in well and the ELDM especially is unfussy. I'm shooting them at 2.950" over 54.2 g of h4831sc out of ADG brass. Both bullets had several good nodes. Both had great accuracy about 1 grain short of initial pressure signs. The 180 will jump a lot compared to the 175 at the same COAL/throat but it actually handles that jump really well, I was shocked.
I had low success with the 7977/h1000 burn rate, no accuracy to speak of, but I don't like compressing and I was using fed 210 primers, hot but not magnum. I never tried 4350 because 4831 is such a clean slam dunk and I think case fill would be a problem. I bet RL 26 will light your life right up. What little data I've seen for the combo it seems like a real freak.
Anyway, just my findings. Sorry I have no MV, I just got my first used chrony and haven't shot over it yet.
