Damn it! I've just got my 7m08 shooting 0.5MOA 3 round groups with the Winchester Dear Season XP (copper core) and its dropping everything it hits beautifully. Now I've gotta find a copper replacement!
This video I found super interesting when considering the merits of each type of bullet: https://www.youtube.com/watch?v=C_oYH_dXGDM takeaways:
- Copper bullets seem to expand better up to 300 yards (or whatever their required velocity is for expansion), beyond that lead was better.
- All bullets perform very similar
- American's didn't seem to realise that hitting the shoulder would cause more shock, expansion and therefore takedown... isn't that obvious?
- There's a point in the video where they don't like the mid gel (body) expansion of the lead core bullets or the fact that they start tumbling. I'd disagree with that point. I know from my Army days we were told 223/5.56mm was intentionally fatal due to the shock of expansion and the mass damage caused by a tumbling bullet.
