I knew that the heavier arrow would keep it's speed longer, but what I am interested in finding out is at what distance the lighter arrow has actually fallen more than a heavy arrow. I'll slap a 500 grain fatty together and see what happens at 50, 60 70, 80, 90, and 100 yards. If it is higher, I will be switching. Based upon my findings, I may or may not switch. As a science guy, this is kinda my thing. I just have never tried it. I will probably shoot my light arrows for 3D because it is a little more forgiving if I misjudge distance. At least on the shots less than 40 yards, which is most of them.

If a recurve can go 90, then an 82nd should be able to do a lot more than 100. I'd like to get out to 120, and if a heavier arrow will get me there, then I am all for it. I'll just need someone with OT2 to help me find one that is spined correctly. I have a mac, so I can't get it.

Science is my thing as well to say the least. Engineering here! I think the arrow weights will have to be relatively close for you to have a usable outcome b/c if you put a 500gr. arrow on vs your 360ish the effect of the heavier wouldnt come into play untila much further distance.

Biology for me.

Ok, a 400 grain arrow. I need to have some one with OT2 spine me for that. Which shaft?

Re: Why the E Clip came off.....

The reason your eclip came off is the same reason your bow is loud.... your arrow is probably too light. If your axel was sticking out an extra .5" from your limb... it may not have been in the limb at all.... which probably means that your axel is bent... bearings are shot..... cam is bent.... or all three. Infact, I'm kinda suprised it didn't break the limb or just blow up in your face all together.

Vibration will do terrible things to a bow man. It should be covered under warranty.... make sure you take the cam out and lay it on a flat surface and check it over to make sure its still straight... otherwise your bow will NEVER shoot right. Roll the axel too.

Will do.

My arrow is more than 5 gpp, so why is that too light? If I need to shoot a heavier arrow, BT should have told me that. They say 5 gpp and I shoot 5.027 - 5.062 gpp. I understand that it is close, but... dang it. I was planning to own at techno hunt this weekend. That won't be happening.

My 70 lb Black Ice is shooting in the 280s with a 419 gr arrow and is shooting really quit. The string rubber broke off and the doesn't make any more nose that it did beforewhen they were on.If your bow that nosy I would say you have some thing loose are a bow really out of tune. Heaver arrows is every ones answer and is not always the right answer.

What is your arrow weight?

Think about it like this.... 5gpp is the gold standard.... its the same pretty much for your soft shooting Parkers and Fred Bears as it is for you super hard draw wrist rockets like your 82nd. Which one do you think is storing more energy and has more vibration?????

See... my HCA Iron Mace is warrantied down to 3.5gpp..... you don't know nothing about speed black stick.........try 370s on for size..... and she is still covered under warranty.

367-369.5 grains. I always weigh all my arrows. I am considering using wraps and 5" feathers instead of 4" feathers to both give the arrow more weight and help stabilize it at longer distances.

I know that there is a lot more vibration in a super bow than smooth bow. They have a lot more KE and like you said, that energy has to go somewhere and unfortunately not all of it makes it to the arrow.[:@]

I've shot 370 out of a super-tuned x-force at IBO specs. I just thought that was way to much speed. Speed is cool to a certain point. I have to admit that those Barnsdale limbs are pretty impressive, but I still like the feel of my 82nd the best. My 82nd is right where I like it and that is why I bought it. I know speed, and I know what I like.

What I would like to see is a super-tuned HCA Speed Pro with a 3.5 gpp arrow. That would be impressive. Maybe 380???

take a picture of the backside of your cams. just a threory after looking at mine and making a few adjustments.
