As aboce use a magic short bow if you do not have that much money. If you have mills to spend use red chins (only use these when you get 92 range, cost mills but the xp per hour is great)
I personally suggest using throwing knives, they are great a little hard to get these days but are the half way between chisn and Magic short bow (MGS)
(I have over 20 mil xp in range atm, any more Q. just pm)
