I'm not familiar with that arrow, but yes they sound deadly for whitetails.

If you can weight them you'll know if they are too light for your bow.
But I'm thinking most 28" 45/60 arrows with a 100 grain point should land you between ~365& 390 grains which is above the normal minimum of 5 grains per pound. 5gpp would put you at 320, 5.5= 352, 6gpp= 384.

If it is shooting great and over 320 grains total it time to sharpen them heads and do some scouting.
