Okay, there' s another problem. I don' t know how he got a 300 grain aluminum and a 600 grain aluminum, both 22XX series and both spined correctly for a 50 pound draw. The lightest 22XX series is the 2212 X7. Maybe with a lightweight nibb point and 1" feathers? A 2219 XX75, even a full length 2216, will make 600 grains easy with a 125 gn field point and 5" vanes. But there is a HUGE problem with spine issues, different aluminum alloys and there cannot be any similarity at all in fletching style or point.

Thinking out loud here. If I do cut and paste a letter to the editor, it' s going to be a wooly booger! I' ll hit Wally World after tonight' s football game and see if they' ve got a copy. This is starting to really sound like an interesting farce.
