I received a Sig M400E for Christmas and would like some recomendations on some decent low cost ammo for plinking.I am on the fence about purchasing some WPA,most sites has it available for a little over $100 per 500,but it has lots of mixed reviews.I understand you get what you pay for,but I would like to hear from you guys with some real world experience with it.Also feel free to recomend any other brands that would fit the bill for plinking.By the way I am new to the forum and first time poster so sorry if this is a question asked frequently,mods delete if my question is posted in the wrong sub catagory.Thanks Roger
