Title: Carbon Express 250 "Actual" Spine
Post by: tzolk on October 01, 2012, 09:14:00 AM
Does anyone here have an actual spine tester that has tested a CE Heritage 250 to see what it actually, numerically, spines at compared to its specs, which I think is. 372ish?  Just looking for the data.

About 80# on my spine tester, 26 inches between the posts, 2# weight. That would be an actual .325 deflection.

Interesting! I have been trying to tune some to my set up and maybe I am reading the tears wrong. Your data would suggest a stiffer arrow than advertised. Makes me re evaluate what I'm doing. I was thinking maybe they were weaker.

When I had some, they spined about #84 same as a 2216.

Eric, funny I was just on the 3 rivers spine calc and a 2216 cut to 31 with the 145 point weight was just what I was eyeballin before you posted here.

I have carbon Express "200's" that I have had for quite some time and they indicate on the shaft that they are spined for 45 to 60lbs. Hope this helps you.
