Your arrows arent going to be light with the factory inserts! It SUCKS b/c i know you were looking at getting some good speed out of em' and now your probably realizing that they arent much lighter than other arrows[:@] I did the same thing with the last bunch of xringers that i bought. Instead of just buying the glue in inserts i thought id be cheap and just use inserts with 100gr. heads

My arrow weight went from 320(giveor take 1or2)to 353[

] I was pissed to say the least b/c my Maxima 250's weigh 355gr. So now, after fixing the last ones up, ill be getting glue in pts. again.
BTW, take your time when glueing in the points on the victory shaft. Ive lost many a points in targets, and they aint cheap at all. Try and burr out the inside then swab it clean with a qtip and acetone, then water...
