Im late to this party in one way but have a fair bit of experience with light monometal bullets shooting 200 - 250 UK deer over the last 15 years. I have grown to trust the 308 Win firing the 130g TTSX at 3000fps and the 7mm Rem mag firing the 120g TTSX at between 3250 and 3450fps. Both of these combinations put small Roe deer and large Red deer on the deck with authority at ranges out to 300metres. If you swap the bullet for a 180g core lock soft point in the 308 even the small roe deer will run a surprising distance, red deer even further. I havent used many partitions (only one deer shot with a 150g NPT). My son has shot a few Roe deer with a 130gTTSX from his 300 WSM at 3650fps. The results were dramatic but I think the 150g TTSX is looking like a better bet in that calibre as the 130 did damage a lot of meat on the small deer
in my humble opinion it depends on the animal. i hunt alaska frequently and my favorite caribou load is the hornady gmx premium bullet in 185 grain 338 win mag. it is light for caliber but caribou tend to “flop over” when hit decently. i had a complete pass-through with this load from 470 yards. now, I do NOT go light for caliber for dangerous game no matter the bullet construction for anything that can bite you back (grizzly).
