Just have to try different stuff and see. Generally speaking the 165-168 gr bullets give better accuracy than some other bullet weights. But there are no hard fast rules, every gun is different. The Matchkings do not have an exposed lead tip to aid bullet expansion where the Gamekings do. Shooting at paper targets do not require expansion to kill stuff.
If you want to use one bullet for both hunting and target shooting I'd start with bullets designed for hunting. I've never tried it, but lots of guys report good results on game with some target bullets. The 155 gr Scenars have a loyal following who swear they are deadly on game, although not really designed for it. Some hunt with the Matchkings as well.
