Me and a buddy are at a stand still regarding the folowing: i have 125 grain fieldpoints (screw in for aluminums) to go on my arrows which have been flying like garbage. We found that if we replace these with 145 grain heads they fly lije darts. Anyways. I cant find 145 heads anywhere save fir the internet. I did see while online browsing tho that there are weights you can slide onto the back of the head and then screw in. So: i desided to slide lock washers on in the same fashion. It picked the grains from 125-139 grains. Now me and my buddy can not decide weather its a great redneck fix or a disaster of aluminum shrapnel in the face waiting to happen. Thoughts?
