125 gr heads would bring you into the green

Thank you very much!

Thanks. I thought I would have needed a little more weight up front as short as the arrows were cut down. Can you tell what the carbon length needs to be for 125 grain heads?

Can you input actual spine into the program? I have found that it can be a fair amount of variance in the true spine. Might be I need to invest in getting the program for myself.

Looks like 25.75. I don't think you can put in actual spine...

100 gr heads get you the weak side of perfect

Im not seeing an option for rampages in 200 spine. In the program or their website...

Would adding a nock bushing and switching to three 2" vanes @ 6.1 gr ea bring the spine closer to optimal? I'd really like to stay around 460-475 on weight.

The biggest gain to be had is dropping down to 100 gr heads. If you added the bushing and heavier fletching and dropped down to 100 gr youd be right there at optimal. Any weight on the back would help though.

Would that put FOC still around 15%?

The bushing really would not be required. I ran the with AAE max stealth vanes and 100 gr head. Easy changes and looks pretty deadly to me.

30.5 arrow length would of given you perfect spine. Also the program said 58 gr was standard insert weight and being that it made 501gr arrow I went with it.
