I shoot a Rytera Bullet X with a 27 inch draw. (I know Im a little guy) :chuckle: but I had my bow at 55 pounds since I got it and I am going to turn it up to 65 pounds. My question is, what grain of arrows should I be looking at? I would like to move up to a 125 grain broadhead as well. I know I can take my bow in but I was just wondering what some of you thought as well. :tup:

google an FOC calculator and play with that a little and that should help you need all your weight arrow knock insert tip all that stuff to make it work it will also explane foc i think carbon university has one

With a shorter draw and moving to 65# you should be looking at some heavier arrows like the Easton FMJ. Don't play with light arrows and try and make them work by adding more weight in different places (just adds to tuning issues). Just check the arrow charts and find what will work for your setup. Adding the 125 grn BH's will help also.

Actually this is backwards. Arrows are rated for spine at full length. If you cut them shorter, the spine will be stiffer than the rating. So, need to know how long you cut your arrows. I have 31.5" inch draw and cut my arrows to 29.5" (i.e., BHs inside shelf, rather than in front of riser.
Oonce you determine how long your arrows are cut, look at specific manufacturers spine recommendations (i.e., they have tables based on arrow length, BH weight, type of cams or round wheel bow, and poundage.
But, I'd guess you should be shooting a 340 spine arrow.

My draw is 26" and I cut my arrow to 25.5". I'm shooting 60#. My arrow spec is not exactly what the chart stated. I shoot 340/400 FMJ as well as 55/75 Goldtip and CE Maxima. My FOC is within 10-15% though. For hunting I've moved away from the Goldtip and CE to get more momentum because of my short draw.

You will need to be 390 grains to be legal in Washington. So if you are also shooting a 27" arrow you are going to want a shaft that's about 8.4 to 8.5 GPI with Blazers and 125 grain point to meet minimum weight.
Beyond that get whatever weight you want. The elk and deer aren't going to care. And neither will the bow.

Thanks RadSav, that's what I was trying to say, just not so technically ;)
