Picked up these Victory archery HV 350 shafts they are 6.7GPI with 350 spine. after shooting them full length with a 250gr point I setteled on 29.5 inches which makes them 238grs including 4 4"feathers and nock. the snuffer broadhead is weighted to 250grs + 12gr arrow insert that ends up rihgt @ 500gr with a FOC of 24.5% and they fly like darts.
