Staball Match with Hornady 178 HPBT provided much better results.
Same Specs: 1-10 twist 26" proof prefit on a Big Horn TL3.
Lapua 2nd fire large primer brass with Federal 210M all 5 shot groups with a Lab Radar

Ok tried a workup with 168 ELDs Gotta say it's about the worse bullet I've ever tried to load for in any caliber. This barrel hammers one hole groups with 175 SMKs and 178 Hornady HPBT but with the 168 ELDs with both varget and staball match its a .8 MOA best group and goes out to 4 MOA...
What's you sweet spot for Varget, Lapua brass, and 168 ELD ? Searching hasn't turned up too much guessing it's going to be around 44.0 GN? It will be out of a 1-10 twist 26".
