Got about 400 rounds of 300 Whisper loaded up with Berger 215gn Hybrids and Unique for my bolt gun. Accuracy in testing was pretty good with the Winchester brass. Until now all my bolt gun ammo was Lapua brass and mostly 230gn Bergers.

A huge perk of a bolt gun is you can use a lot more powders because you dont have to worry about getting the rifle to cycle.
