Hey guys, I am thinking of changing my arrow selection pretty drastically this season and wanted to hear your thoughts. I am currently shooting a 385 gr arrow cut at 28 3/4 in. I am looking at heavier arrows and am leaning toward the Easton FMJs. My concern is that with my arrow length, and switching to a 125 gr broad head to maintain a decent FOC, my arrow will be close to or maybe a hair over 500 gr. I know I will be sacrificing speed, which is fine with me, but does that seem too heavy? BTW my bow has a 323 IBO, my DL is 30" and draw weight 67 lbs but will prob be 70 by the time season rolls around... Thanks in advance!
With that set-up, you will be rocking and rolling. Your arrows will blow through deer and the 500 grains with 125 up front will knock em dead.
Depending on arrow shaft length and where you want your DW to be you may need the .300 spine shafts but .340 at the least. Other than that you will have a very forgiving arrow that should exceed your expectations.
I would shoot the 125 grain setup first to make sure your bow tunes well with it. The general rule of thumb is, if your broadheads (100 grain) are flying to the left of your field tips, 125 grains will make them fly to the center. I'm not sure if this would cause your arrows to fly to the right, but if it doesn't, by all means go for it. Speed in a bow isn't everything, and since your draw length is 30 inches and draw weight will be around 70lbs, the only thing that will be dropping your IBO is the weight on the string and arrow grains, which means you have a lot of room to shoot a heavier arrow without sacrificing too much speed. That's a recipe for tons of kinetic energy, I say go for it.
I shot 28" Easton Axis 340's with a 125gr. head up front and they flew like darts and weighed in the neighborhood of 427. Probably one of my flying combinations to date. I don't know that you can ever have an arrow that is "too heavy" assuming you don't mind big pin gaps and less room error judging yardage etc. I can't think of any deer/antelope I've ever shot with those arrows that didn't pass through. That has to be in the neighborhood of 40+ animals with those arrows. I like a heavier arrow but after 450gr it's probably a little overkill (for deer). I'll the flatter trajectory after I get around the 400gr mark.
