What will my arrow speed be?

[face_reality]

I have currently purchased a Diamond Justice and I am wondering about what my arrow speed will be.
I have a 26inch draw and am pulling 70lbs.... using easton powerflight arrows carbon 400 with 100grain tips or broadheads. I have a peep and notch point. Any ideas anyone? thanks a millions I think diamond says that bow is capable up to 311

I would guess about the 260 range.

anyone have any reviews on the diamond justice? also what would a max shot be with this bow? Thinking about going with maybe one or 2 pins? So dont know the distance I would be able to shoot. Or is this a practice and see where I feel comfortable? I would love to able to use one pin but I heard you have to be near the 300ibo speed to do that.

Speed has nothing to do with how many pins you use. In fact the slower the bow the more pins one would like to have. I shoot to 60 and 70 yards. I use a five pin spott hog. I am only shooting about 250 but I also am shooting 543 grains. I use a 220 grain Muzzy Phantom broadhead, at 21 % FOC.
When I shoot 3D and lighter arrows, I work real hard to keep it under 280 FPS.
Get your self a 3 pin sight and you'll be fine. Set them at 20-30-40 yards, and you'll be fine.

Why do you try to keap it under 280 FPS???

Because some of us shoot our bows year round and shoot venues like IBO, ASA and such. Some organizations have set speed limits to give good shooters an even chance with those who just rely on speed to level the playing field.

Dealing with the single pin idea. It is very possible to hunt with a single pin, even with speeds of 260 fps or so. You don't need 300 fps. Don't get the idea that 300 fps or more gives such a flat trajectory. Within reasonable hunting distances there is very little difference between 260 and 300. Maybe 1 1/2" at 25 yards. If anybody tells you they can shoot the same pin from 0-30 yards and hit the same spot they are either lying or have no idea what they are talking about.

Assuming your bow shoots 260 fps, you can set a pin for 25 yards and then shoot it at various distances between 5 and 35 yards to see where your arrow hits. Here are some typical results you should find.

5 yards---0 (same as 25)
10 yards-- +1"
15 yards-- +1 1/2"
20 yards-- +1 3/4"
25 yards-- 0
30 yards-- -3"
32 yards-- -3 3/4"

I never shoot beyond this for hunting due to foilage. However it should show that a mid body hold on a deer between 5 and 3 yards should result in a dead animal. No trying to determine yardage or calculate holdover or under. Just aim and shoot---and keep aiming.

Now what will 300 fps add to this? A little flatter, meaning you can add about 3 yards to the final tally. For 3D it will be a lot different because the typical 3D shot is not between 5 and 30 yards.

So for hunting i would be better of with a heavier arrow which should result in better penetration and a quieter shot right? But for 3D tourney's go with a lighter arrow to get my fps up right?

That's direction most archers are going - although I still think you can effectively use a lighter 3D type arrow for lightly constucted animals like pronghorns - where distance shooting is a distinct possibility. Mostcompound shootersI know are using a "medium" weight arrow for general big game hunting on this continent. Something in themid 400 grain weight range.

Are my 354grain arrows considered light? what would be considered a heavy arrow?
