I’ve built three Defiance lightweights now. I like all of them a lot.
First was an Anti (not the X) long action with a 24” proof carbon barrel in 7 Rem Mag (back when that was a prefit they chambered). I’ll rechamber it to 28 Nosler before too long, but I really like how it turned out. Ive taken two cows with it now, but the long barrel really wasn’t a great choice on the cusp of everything being suppressed. 7 Rem Mag seems an archaic choice with the PRC chamberings that have come out since, but I had a lot of ammo for it. I don’t carry it much anymore, too unwieldy with a can on.
Second was another Anti (not the X) but a short action. It got an 18” 6mm Creedmoor barrel from Rainier Arms. Super happy with it as well. This is one of my trainer rifles, particularly for long distance shooting.
Third was a Ti-X medium with a 20” PBB .750 taperless fluted barrel in a long throat 300WSM chambering. This build combined what id learned from the others, particularly the lessons learned from the 7 Rem Mag build, and was specifically built as a lightweight meat hunting rifle using high BC copper monos (192gr HBC). I think I’ll get a lot of use out of it, I just killed a cow with it this week. WAY easier to lug around than the 24” barrel long action.
As much as I like the Defiance actions, the BAT Vesper is significantly superior in the same weight class as the Anti. I had UM build me a Vesper short action in 6-284. It locks up like a bank vault, and the bolt throw is significantly smoother and with less slop than the Defiance actions. You pay more for the Vesper, but you can certainly feel what you paid for when you run the bolt.
