Yes, Id is the same I can use all my spare nocks and inserts in either shaft. If you want fast, new ones weigh 7.3 gr per inch, nock is 20 gr, alum. insert is 30. If I add them up, I get 196 gr for a 20 inch. My excal needs 350 min with tip. So I must add some weight somewhere.
Hope this helps, Almost all Cb's have a min. weight for the bolts, So please check.
Lotsa Luck, Stan
Stan: 7.3 gr X 20 = 146 plus 22 gr alum nock = 168 gr + 27 gr for 4" vanes = 195 gr + 110 gr brass inserts = 305 gr + 100 gr points = 405 gr w/ about 19% foc, fly like darts. W/ 8.6 gr shafts add 26 gr for 431 gr [Millers killers] still fly like darts. Much better performance than 350 gr minimum, quieter, easier on bow and they only cost you 14 fps if you use FFF string.
