being new to archery hunting. I would like to know what arrow weight is a good weight for hunting

My draw length is 27 inches. 60-70 lbs draw weight. Bow speed is 300fps ibo. So I believe I would use a 28 to 28 1/2 inch arrow correct?. I notice that most CARBON arrow fletched nocked and have incerts weight between 7.9-9.45 gram per inch

So taking the numbers 28 inch arrow times the min weight of 7.9grams +100 grams for the broadhead would be 321 grams.

Is this correct?
The reason I ask is I dont want to be misslead when I go in to buy my set up.



Any Guesses on speed and knetic energy for arrow. I am going to have the bow I buy cronoed so I know what its doing before I leave the shop.

Would 245-250fps arrow speed be correct for 64 lbs draw weight?


Like to be informed so I know when the wools coming over my eyes
Thanks in advance
