Arrow length

Happy new year, I am sure it's possible too shoot 20 inch arrows out of an excalibur bulldog 330 that shoots 18 inch arrow, any difference?

Happy New Year to you.

For every 10 grains over what the manufacture supposedly used to obtain their advertised speed, a well tuned crossbow will lose approximately 3 feet per second.
Adding length to the shaft only will increase the weight per inch. Some bare carbon arrow shafts weigh more than others. Different vanes, even the same length can result in weight difference. Nocks and insert weights can vary.

All the best.

I shoot a 16 inch Spinal Tapp arrow out of my Matrix 330, it’s not to short and really shoots accurately. Total arrow weight is 425 grains with a 125 grain broad head.

Obvious weight difference aside, stability in flight would be better with a longer arrow, would it not? For the purpose of discussion of arrow length alone, eliminate variables such as FOC, different weights by comparison, etc.

Absolutely it is.
I shoot 21” arrows out of all my bows for both tournaments and hunting.

Thanks everyone

A longer arrow will need less weight up front to get a good foc percentage. I shoot 18.5" arrows out of my Matrix 350 with great results.
