The maxima hunter 250 is 8 gpi...NOT 7.3 The regular ole, non camo maxima is 7.3....

26" arrow at 8 is 208
100 grain tip

308 + 11 grain insert = 319 = 4 grain collar = 323 + 9 grain nock = 331 + (depending on what fletching you will be using) 20 grains = 351.....

Yes, you are going to be very close. You have a few options though. You can turn the bow down to 68 or 9 pounds, you can add a wrap, U can go w/ a 125 grain tip.....

I'm not sure how close you're wanting this to be...But I think, if it were me.......I would cut them 27" long and go w/ the 350....You'll be around 365 grains @ 27".....just off the top of my head, rough estimate...
