RE: ontarget anyone?
I was asking in regards to spine.
I wanted to know how long the shaft would need to be to give me the ideal spine for the given parameters.
I got the program to work now so it's all good.
As for chronoing, I didn't chrono, @ 65#, DL 30", 375 grn. arrow, I was shooting 280 (with only a peep and d loop on the string) with a new winners choice string on) and the IBO is 310.DIdn't sound right at first, but after thinking about it doesn't sound like it's close to where it should be.
