RE: Beginning thoughts
A few thoughts, I hope this helps you.
2114's are9.9 grains per inch. At 28" that's 278 grains + 125 grain broadhead = 403 grians +25 grains for feathers, insert and nock = 428 grains.I don't know if42#s will cast a 428 grain arrow 150 yards. Maybe. You would have to test it.
If you went to50#'s with a 450 grain arrow. Thearrows should still work witha 125 grain broadhead at 28" back of point.
