Short draw hunting setup question

[Autumn Sunrise]

Hi all. I am not the most seasoned traditional bowhunter.  I've been doing this for 3 years now and have a hog and a whitetail buck to my credit.  I'm hoping the more experienced here can help me out.
Right now I shoot a 60lb Kodiak Magnum-at my 25" drawlength I'm guessing that's 50-52lbs.
I made up some high weight, high foc arrows- 630grains, 27.5% FOC.  They fly great, couldn't ask for better flight. Then I shot a 3d course and got served a slice of humble pie.  Talk about arc-goodness!
My question is this- do I, as primarily a deer hunter, need this kind of arrow?  Range estimation is super critical with these feather rocks.  I do have another arrow setup, 530 grains, that also works well.  I'm starting to think that extra 100 grains ain't worth the hassle.

530gr is plenty to kill a whitetail. Hit well and you'll collect your deer. That is still a heavier set up than more than one of use is using. I'm drawing 45# with a 487gr arrow. There is a thread on here about deer taken with 40-45# bows; it went many pages.

I shoot a 47lb Palmer recurve at my 26" draw and hunt with arrows ranging from 480 grains thru 530 grains and have never had a problem with penetration on deer and hogs. I use big broad heads too like the Palmer Extreme Cut, snuffers and 4 blade Muzzy phantoms.

What has worked for me is to use a big broad head and not to crowd the shoulder.

450-460 grains will get you into the 9 grains per pound range and out of the 12.5 gpp range that you are currently in. You will notice quite an improvement in trajectory and plenty of arrow for hunting.

I used a 500 grn arrow out of my 50# longbow which I'm only pulling to about 26.5" so about 46-46# with a 175 grn vpa 3 blade last year. I shot a buck and had complete pass through with no problem. I'm sure the heavier weight will help with some other animals like hogs but don't think it's needed for whitetails

[David McLendon]

I'd hang on to the heavier arrows for hogs, where depending upon the size of the hog a heavy FOC arrow would be an asset. Deer being thin skinned and lightly boned are mostly made up of water and a well balanced arrow in the 9-10 gpp range is more than adequate, in addition to having a flatter trajectory.

I agree with Dave.
