      Ok, Arrows and I have a love/hate relationship.

      I love playing with new set ups, and materials.

      But it drives me crazy at times.

      I know I’m not alone!

      So, my question is, how much does weight affect trajectory?

      For instance, say my hunting arrows are set up at 600g. with a 190 gr head, and I want to stump shoot with the same bow and arrows but want to use judo heads and they weight in around 525g. Does this much weight difference affect the trajectory enough for the brain to mess up?

      Or, am I over thinking all this!?

      I think 75 grs make a diference after 15 meters

      On another hand lights arrows lose speed faster than hevier

      Everytime you moove weight you have to train a few days

      Brain is a nice machine but you have to be patient to get a new goal

      Please don’t take this the wrong way, but it depends on how well you shoot. To a new archer who struggles to hold paper plate groups at 10 yards, 75 grains of spread in arrow weight is probably a moot point. The difference in impact is well within the archer’s margin for error anyway. Now take a top 3D or paper shooter and 75 grains would be immediately noticeable because their nice tight round groups would open up vertically. To me, it’s just as easy to make arrows that are well matched as ones that aren’t.

      If you’re using screw-in points, try switching adding a heavier adapter to your Judos to get the weight up. If you’re shooting glue-on points, you may want to consider a 200-grain Hex Head. They don’t make them in 190-grain weight, but 10 grains is going to be a nonissue for stumping anyway.

      I agree.

      I was just wondering.

      I shoot wood. And Judo’s come in 135g (11/32)

      I might just try and use hex like you sugested, or screw in adapters(50G)with 125 screw in Judo’s

      wojo14 If you are concerned about the 75 grain weight difference you can add a 75 grain woody weight between judo and arrow. I don’t like extra connections but on practice arrow for stumping it is not as critical as if on a hunting arrow.:D

      I was able to match my judo arrows to my tuffhead arrows by using lighter, 75 gr., steel adapters and a 50 grain insert with the tuffheads and a 125 grain steel adapter and 100 grain insert for the stumpers. Better to make them match if you can. As most of you do, I try to make my stumping shots as accurate as my target shots, since they’re all target shots. Have fun with the crazy! dwc
