My M38, sporterized, loves the Sellier and Bellot 131 gn soft points and shoots three to under an inch at 150 m. The ammunition is inexpensive enough and reloadable, if I think I can either get or need better performance. It is an excellent performer on whitetail.
The Hornaday Light Magnums are in the same performance range as good reloads.
The 6.5 Swede is known for being a game getter beyond most proportions. It is an incredibly effective cartridge. 120 - 140 grn bullets are very effective on whitetail; for hog, small to medium bear, moose and elk the 140 gn bullets are very good. For anything larger, including hipperonisauri and other monsters of that order, the 160 is excellent. Mikey.
