I recently purchased a new Morrison Shawnee recurve (48lbs @ my 27" draw w/ carbon foam limbs). Well just got around to fine tuning my arrows this weekend and it seems to really like 600 spine traditional only arrows cut to 29"
with a 125 gr stinger broadhead. This setup flys better, faster, flatter than anything I have ever used but Im concerned that the arrow broadhead combo is to light for hunting at only 328 grains( 7GPI @ 29" + 125gr. bh). Would really appreciate your thoughts,opinions and experiences with such light arrows on game.

I'd be worried about the effect on the bow of shooting an arrow that's 7 grains per pound of draw weight.  Morrison's are tough bows, but that's almost like dry firing the bow.  I'm sure you could find a heavier spine, weight, point weight combination to get you in the 8-10 grains per pound of bow weight range. My guess is you could easily add another 100 or more grains to your set up and still get excellent arrow flight. I don't shoot anywhere near that light, but I've found that slower, heavier arrows are more stable than extremely light, fast arrows, and more forgiving of shooting errors to boot.

Weight tubes?

Thanks for the comments. Makes me nervous about hurting the bow also. It is still quite and smooth with the light setup but its so far from the norm that Im concerned. Trajectory is nice. I bought a trad only arrow test kit and point test kit from 3 rivers. Seems odd
but my bow liked the extremes. A 300 spine with 250 grains upfront shot good as did the 600 mentioned earlier. The middle arrows never seemed to get close to the 300 and 600 from a flight perspective. Ill play with tubes and points.

What Orion said ... Seriously,, Too Light ...

I would definitely go with 50 or even better 100 grain brass inserts.

yikes!  at around 7gpp that's too light an arrow for that weight bow, something's gonna give and it won't be a pretty sight.  you wanna up the arrow weight to at least 8gpp, which in yer case means at least a 390-400 grain total weight arra.  up to a point (pun not intended!) heavier will offer some good advantages in penetration (assuming the head is 'sharp'), smoother release, quieter.  most bowyers won't warranty a bow shot at less than 8gpp.

Its hard to add weight to a completed shaft without tubes. If you add weight up front your spine changes and now you new arrows are not correct. Tubes have downfalls; as most gadgets do, but they work without buying new shafts. Try them out for a few bucks before buying all new shafts.

Take Stu's calculator and put the arrow in that is shooting great.  Then switch shafts to a stiffer spine and adjust the point and insert until you get the same spine number.  It'll fly great.

step back to old school and how we did it before "traditional" carbons,,,,,, get a roll of weed wacker line and pull the nock off the back of the arrow and feed 1 to 4 weedwacker lines inside until it hits the insert up front and then cut them so about a 1/4" is sticking out the back and then push the string nock back in and weedwacker line doesnt not effect spine (or never did for my bareshafting)  you can put 1 to 4 or 5 until you get the weight right,,, where your worried about spine this might work for you in a pinch..  

I had 2 morrison dakotas and they where loud with 10gr an inch for me (until I got FF strings with padded loops) not sure how loud your bow is but I know it will be quiter with a heavy arrow and you won't split a limb up the middle and void your warranty.

for hunting the real thing  I'll opt for quietness over speed all day long but try to find the perfect mixture and I use heavy inserts and heavy points too.

I've had great luck with 424 grain Beman MFX Classics out of 46# bow at my 26" draw this year (28" arrows). However, I'm going to tinker around and get the arrow weight to around 500 grains after season and see what that sounds and shoots like.

To do this I'm going to try to go to Beman MFX 500s instead of my 600s. I'll reduce the 75 grain brass insert to 50, and I'll use a 150 grain broadhead instead of 100.  According to Stu's Calculator this will work very well -- a much better match, according to "Stu" than what I'm having great luck with this year.

3-4" parabolics, alum insert and nock weighs 30 grains. Bringing your weight up to 7.5 grains per pound. 368 grains. 384= 8gpp your close.
keep shootin, I know your havin fun!!      

Most bowyers recommend 8-10 grains per lb. Your about 50 grains shy of that. I would like to see you at 400 grains minimum but its all up to you.

Some bowyers won't warranty a bow if the arrow weight is too light. Personally, I'd call Morrison up and get his input, he may feel your Ok with your present setup.

Yea, I'm thinking that's too light also but not so much in concern for the bow as concern for penetration performance on a deer.  Not sure how that would perform if you hit something like a leg bone or shoulder blade.

Thank you everyone. I rigged my old reloading scale to weigh arrows and as TNStickn pointed out I was heavier with feathers and inserts than I had estimated.  I have since bumped my total weight up to 430 grains(8.9 GPP) and still shooting good so I think Ill stick with that for now. Hopefully I can test it out on a hog this coming week. Thanks again for all the ideas!

9-10 grains per # of draw wt! Both you & your bow will perform well !
