Shot SW4350 2 days ago and did a direct comparison on charge weights to H4350. I run 40.6gr of H4350 for my match gun behind a 140ELDM, with CCI BR2 primers in Peterson brass. Build is a TL3, 26" RCB from PVA. Labradar, sitting at 6k' above sea level, and in 50-degree weather @ 100yds.

The only reason why I did this test is because of the dry up of H4350. I'm looking at alternatives. No pressure signs are seen on any of these loads in my gun, and bullets were seated +/- .0005 off the lands. Accuracy with SW4350 wasn't "great" ie, all loads around an MOA which I consider pretty bad. My H4350 load shoots in 3's usually at 100yds with the 40.6-41gr of H4350. Now, Staball has caught my attention, and I like it because it flows through my dillon. I did not load these 2 series on the dillon, but I am going to pursue it further.
On the other hand, SW Match in my 24" 1x7 223wylde AR is a match made in heaven. I also have SW Precision and my 6br so far is not a fan.
