Daisy, hammers just pulling your chain. There are alot of ways to go with the 6.5, if you plan to stay with the 120gr then a 1/9 will work fine. If you might want to try a 140gr down the road then as stated above the 1/8 will give you the ability to do both.

I have two .260's at the moment, a 22" and a 24" both in 1/8 and both shoot good with light weight or heavier weight bullets. I will either cut down the 22" to 18" or 20" for my brush gun or perhaps get a .260 lwh, i simply will wait until i see some reviews of the lwh before deciding. Either way the .260 will do fine for you. blue
