i just got a .223 wssm and havent shot it yet. i havent even bought shels for it yet. i would like some advice from everyone that has shot them on which ammo, bullet weights and that sort of thing. i need the advice.

Any bullet that shoots good in your gun would be suitable for Varmits. If you use it for deer I would use the Barnes X bullet, Nosler 60 grain Partition, Speer trophy bonded or the Hornady and WW 60 and 64 grain bullets. I don't know what is available for factory ammo but check Midwau USA or another good ammo supplier. Many use FMJ's to limit pelt damage if you save the pelts.
