Trad Gang

Ok, so with advice from hangers here I learned I needed heavier arrows. I'm shooting GT 3555 cut to 29" (26.5 draw) out of a 55# samick sage. I've measure the bow at my draw and it's pulling 53#. I put 100gr inserts in and with an old 125gr Muzzy 4 blade trocar tip total weight was 496gr. I wanted to get to atleast 10gpp so I wanted to add 100gr. I called the only shop local that I know carries some trad stuff. They didn't have the screw in weights. So what I ended up doing was cutting a length of 14ga electrical wire with some shrink wrap that came out to 100gr. I then cut in half, twisted it and shrieked wrapped the ends. I stuffed these in behind the insert. They fit really tightly and I'm not worried about it moving. So now total weight for all 4 arrows is +-4 grains from 595 grains. They are amazingly accurate. I was easily getting 3" groups at 20yds. But they do look like there is some tail movement during flight. Not much, but a little. Is it possible the 3555 is now too weak? I could cut some off if that would help, but I'd like to keep this weight. Also I'd like to make these work rather than have to go buy new arrows. I know the sage is cut slightly past center and I only have a small piece of felt as a side plate.

I would recommend practicing at 10 yards and see how they group. If they still group well, try 30 yards. If they still group well, I would not worry too much about a little movement.

Could be right, could be wrong. One thing I can say for sure is, if you added 200gr to the front of the shaft, it is waaaaaaaaaay different than it was before. My gut tells me that you are probably too weak now, but that is only a guess. You will only know for sure by doing some form of tuning. Only personal tuning will tell you for sure what you need to do to that arrow to make it perfect.

Watch because any crosswind will cause tail movement as well, even with a perfect "everything else".
Also, tight or not, if not glued or screwed those inserts can maybe move. Plastic tubes are notorious for kicking nocks out the back end no matter what you do to make them tight.
