Hey Guys, first of all happy memorial day to all especilly you vets out there    I'm trying to add some weight to my arrows by inserting weedeater string and my problem is that when I shoot the nock pops out from the impact. I'm shooting Gold Tips. Any suggestions?? Thanks  

i use wal mart bags stretched over the end and push my nock in makes it alot tighter

Make sure that you didn't damage the nock or the back of the shaft.  If the back of the shaft gets a small crack they will pop out.

Get nock inserts and use glue-on nocks. You'll never lose another nock again unless you shoot it with another arrow

Thats the only bad thing about weight tubes or weedeater line,on a hard hit it will pop your nock out.When I use weight tubes on some GT's I switched nocks to some of the old GT lock nocks,and they would hold in pretty good.

Thanks Guys, I went out and tried the wal-mart bag trick and after several shots... no pop outs      

ya the gentleman that owns easton showed me that trick at the ibo triple crown 3years ago

If you use weight tubes you can pinch them in several spots with a needle nose pliers this will help keep it in place.

like in the middle or where

oh ya if they do start too come out after awhile just put another piece of bag and do it again,,,cheap fix
