For hunting, I am a HUGE fan of full copper rounds.
For many reasons.
1. Look at X-Rays of animals shot with plain lead bullets. You are slowly poisoning your family.
2. Copper bullets weigh less per size. Hence they are made longer. Hence more contact with barrel = higher precision
in barrels that might not be of greatest quality.
3. They open up in petals (Like many fan blades) and do great work on cutting through vitals. (As opposed to mushroom)
4. When you recover lead bullets in the animal, you recover between 60-80% of the original bullet weight. Copper is over 95%.
5. Cheap savage 110 rifle was shooting 12 moa (6" in any direction from bullseye) at 100 yards. This was using rem 150 and 180 grain bullets... Hornady 165 was a bit better at 9 MOA. Tried Copper Barnes vor-tx TTSX rounds. Hitting 1.5 MOA. 168 gr.
As for practice, I haven't shot Federal Lake city, but I hear that is THE BEST brass and practice ammo you can buy for practice.
I personally have NOrinco copper washed, and Hirtenberger... Copper washed sometimes splits casing, and accuracy is meh.
They have 3mm of play in total bullet length from one to another (same batch) Hirtenberg is MUCH better than NORC in my rifles. The bolt doesn't need to be slammed shut in the savage 110, it feels more like a 308. Some Hirt is reloadable. (depends on year of manufacturing.)
Bolt gun is hitting 8 moa with HIRT. Which, is better than with Remington corelokts. This gun is a cheaper, 30 year old gun.
Not the most precise firearm out there, unless I am using Barnes Vor-tx TTSX 168 grain.
Just be careful, there is TSX rounds, and Tipped TSX (TTSX). I prefer the tipped.
Maximum range with these copper rounds is about 400 yards though for a good kill. Bullet doesn't open up properly under 1,900 fps, which is roughly 400 yards.
