Arrow build advice

[thump]

Only got around 6+ inches of penatration with a 455grn arrow that was bare shafted, with a sharp magnus from my 46lb  toelke whip. The shot looked really good it was 22 yards away Arrow stuck fast possibly a little high behind the shoulder, I did find some bone on the Broadhead which I recovered 450 yards away.Very sparse blood so now I'm second guessing this build. This is my first year with carbons I love the way they fly but I need a little bit more assurance.

I have four dozen Easton axis 500s to work with these l can cut  down between 29-28" which leaves me two more builds. One with 225 up front for a total of 477 arrow weight. And the other is 250 up front for a total 495grn Arrow.

Shot thru a nice buck last year with a 40 lb. bow   Easton Axis 500  29 1/2"  580 gr.  100 gr. brass insert 200 gr. Grizzly 160 fps. 24.5 foc. 31.7 f-lbs. 60 yard recovery. I think you might a hit a bone.

It's not arrow weight that 's the problem, it's arrow placement.  Bone on the broadhead means you did hit bone. Given the high hit, likely the off side shoulder.  That will stop most arrows, particularly from a fairly light bow.  30-40 grains more arrow weight wouldn't have made any difference.

Orion is correct. 20 grains isn't going to make much difference on a bone hit with an arrow that light, especially out of a bow at 46#. Another 150 - 200 grains (if you can shoot well with the new trajectory) on a well tuned arrow out of 46# would make a difference when coming in contact with bone. Arrow placement can't always be controlled when animals start moving while the arrow is on the way. I've shattered the humerus bone on impact at 17 yards and busted through the scapula on the far side of a whitetail using 42# and 47# bows. Both animals went down quickly.

Thanks guy's, I think I'll start to limit my shots to under 15yards now that I'm Shooting lighter weight bows also. And adding 50 more grains up front can't hurt either.

That is never a good feeling but it happens brother. I have to agree that you high hit the offside shoulder bone and that more weight would not have increased lethality. A single bevel hair popping sharp may have given you an exit wound that would have allowed more blood and further tracking maybe not but if so, likely to the same end.

Like others have said it's all about shot placement but I can tell you this in the past my heavy 670ish grain arrow has saved my hide on animals that I've made shoulder hits on.
 I wish I had the photo of the hog I hit in the shield. The arrow was buried 6" from the fletching on a 127# hog. I'm not sure a lighter  faster arrow would have had the same outcome.
