Looking to increase arrow weight with current arrows. Current setup is hoyt alphamax 35 with 27" draw length and pulling 65lbs. Arrows are gold tip hunter pro 340 8.9gpi. Arrows are 27.5" from nock grove to end of shaft. Arrows currently weigh 400. Would it be best just to add the weight to the gold tip insert? Was thinking about adding 50 grains to get too 450ish. Or will I need to get different arrows? Thanks

I don't use the programs but that would be to weak IMO. You really can't over spine but you sure can underspine. I'd go with new arrows. You'll get some answers soon good luck.

Best way to tell is just get a field tip that’s 50gr heavier than current and see what happens. Would probably be underspined especially with broadhead though.

Adding the screw on weights is the easiest way to go that’s what did. I think you be borderline on to weak but it would probably work. Just add the weight to an arrow and shoot it and you’ll know right away.

Any recommendations for correct arrow spine and set up?

Cut your arrow to 27”and add 50 grains to front and for your setup. The 340 spine are fine. Running your numbers your perfect dynamic spine is 376. So with your 340 spine cut 1/2” shorter with 50 grains added to front will be right. The ibo on that bow is between 312 and 321, and a shorter power stroke your arrow will do the job.

Once you figure out how much you want to add and the correct spine I highly recommend the ethics archery insert / collar system. Good way to add weight but also really strengthens the front end for impact

6mm Easton Axis 300 Spine with 50 grain brass insert (27.5" from nock grove to end of shaft) will weigh around 453 grains.

.300 is gonna be stiff. I would cut the .340 to 26.75” assuming you have room on your arrow shelf. Then add a 50 grain insert. You’ll net 43 grains more than your current arrows and the shorter arrow will stiffen up. You could definitely get away a 75 grain insert as well.

Being a little on the stiff side is a Good thing.
