I have a css encore set at 52 lbs and its only shooting at 203-207fps. I am probably going to move it up to 57 lbs for hunting.

What grain arrow would you think i would need?

What type of arrow would you suggest?

some states require a minimum arrow weight, might want to look into that before you decide!! Just somthing to think about.

I think for hunting they recommend 6 gr. per lb minimum -which means at 57 lb.you want 342 gr total. This includes arrow,fletching,and broadhead.
