Used these bullets in a 6.5mm rifle for varmint hunting. The accuracy was excellent and the bullet performed well in the field. The polymer tip helped with expansion without overpenetration. Good for handloading with proper data.

Great quality for handloading. The boat tail design improved accuracy and reduced wind drift. I’ve used them in multiple shots and they performed reliably in different conditions.
