a little help
 

relatively new to bow hunting only 2 yrs any way im using a hoyt mt with cam and 1/2set at29 inch draw weight is 72.
my question is last year i was using 34 inch easton game getter arrows with a 125 grn broadhead for a total arrow weight of 580 grns.
this year after listening to my freind giving me a hard time about using baseball bats as arrows i got some carbon 340 arrow cut to 27 inches and using 100 grn broadheads total arrow weight around 340 grns. yes it does shot alot faster and flatter and i was impressed. but i am worried if it is to light i mean how light can you go before you are essentualy drie firing your bow let me now what you think and thanks in advanced.

For your draw weight you are too light now you are under the min 5gr/lb

If you want to stick to min weight your arrow should be 360gr for your current draw weight.

Personally I would have stuck with the heavier arrow as they will pack more punch when they hit.;)

RE: a little help
 

Most of the modern bows coming out are warrantied down to 5 grains of arrow weight per pound of draw weight (360 grain arrow @ 72# draw). To me that sounds ludicrously light (and you wonder why you hear so much about limb issues?) Used to be that the benchmark minimum was 6 grains per pound. You could put a 125 grain head on those .340 shafts and probably still be fine with the spine and you'd gain some FOC, you'd also be above 5 gpp (although just barely).

That MT Sport has a magnesium riser and I believe, but not with 100% certainty, that minimum arrow weight was 6 grains per pound. I owned one about 3 years ago and recall something to that effect.
