Thank you to everyone who has responded.

Like Yaddio, I believe future gun legislation will eventually ban all lead bullets. So trying to anticipate ahead

I have 1:8 twist 223rem. For deer hunting, I was thinking something like 55gr ttsx or 62 gr ttsx. Not sure if I should go with heavier bullet since mono metal bullets seem to prefer speed.

If I go with barnes 55gr ttsx as my big game bullet, then try to match up predator lead free bullet such as nosler 50 gr ballistic tip lead free to hopefully have similar poa/ poi.

Just my thought process out loud
