Anyone have any suggestions on loading.
I bought some Hornady #4500 .458 300 grain projectiles. Just can’t really find any load data. I’m using h4198. I also got some Hornady 350 grain #4503 projectiles. Also oal if anyone knows. Any advice would be appreciated.

Just seat to cannelure if powder will allow you can alway play with oal to fine tune later if needed.
Cci 350 work best for me
No crimp or little with lee fcd
I havent played with #4503

Visit the 458 socom forums website....bunches of data and load testing.
