Can’t beat physics. You want more speed for a given weight of arrow. The only solutions are more draw weight or longer draw length
F=M x A. There are only two variables.

If mass stays the same you have to increase acceleration. That means higher draw weight or draw length.

Here's one tip.. don't listen to the guys telling you to jump 15lbs up to 70lbs.. if you try going from 55 to 70 you will most likely hurt yourself or shooting will suffer greatly just by jumping to that. Yes going to 70 will get you more speed but to be honest, with the ibo of your bow being 318 even at 70lbs you'd be pushing getting your goal. you have enough of everything at your current set up to kill deer. Don't chase the speed number unnecessarily, ensure the rest of the setup is correct and then get practicing.

I don't know if this is a true cry for help or just post count padding, but your big problem is thinking you can choose an arrow that has any significant impact on the KE produced by your bow. The KE that your system has is essentially independent of your arrow. Once you've decided on an arrow mass (in this case 410-gr.) your arrow speed is more or less set.

Changing your arrow mass by a few percent will have almost no impact on the KE of your setup. Changing your FOC will have essentially none. All this means that you're asking for something you can't have. You want to increase your speed with a 410 grain arrow? Shoot a heavier bow. End of story.

By the way, don't rely on archery calculators for crap. Archery calculators are some of the worst myths on the internet.
Great post^ and right on the money! You are wrapped up around insignificant factors. 25g of arrow weight…..and/or a few points of FOC doesn’t make a lick of difference.

.
As folks are telling you; drop arrow weight or increase bow weight To increase speed.

If you are worried about penetration, a very efficient BH solves that.

It depends on the calculator to be honest. Some are hit and miss or outdated but some others are fine. However just like everything else in life, common sense has to be exercised. The calculators are a guide, not a bible and far too many treat them as the latter. They can give you a great idea of a starting point but just like everything else in this sport, we are all different and no one recipe will give the same results across multiple shooters. I find the calculators do give a far more accurate starting point than the manufacturers charts

Lighter arrow = more speed
Heavier bow = more speed

you can't change the speed of a 410 gr arrow by moving the weight around. It sounds like you have never shot anything with a bow, and are overthinking it based on things you have read. There are plenty of guys on here shooting big elk without crazy heavy arrows or super fast.
Placement of the shot is going to be more important at this point. Make good shots at close range and you're set.

The dynamic archery solutions calculator is decent. Almost all the others I've used are junk. To be fair, I've not used any of the for purchase archery software, so I can't say if those work well or not. I'm really strictly speaking of online calculators like the backcountrybowhunting.com calculator, which is really terrible over extended ranges of arrow weight.

Stop chasing unicorns. Get a 400-450 grain arrow that tunes from your bow with a broadhead. Forget speed and FOC. It will be fine.

Forget about speed.
My daughter blew thru a buck last year with a 50lb draw weight and 25" dL.
Probably going all of 225fps and maybe a 350g arrow...perfect shot and went 50 yards.
Focus on making good shoots

You could go through arm lengthening surgery. Dey cut your bones in half and stretch your arms. You will look like Clyde but you at least have a longer draw

Random thought.... maybe try the Easton 6.5 arrows. They are faster than an Access because they are lightweight, and it's pretty easy to get the FOC in the range you are targeting. It will be sub 400 grains however, but if you add a heavier insert and broadhead, you might get close to 400g with a high FOC.

I've found I can pickup around 15fps using those arrows over the Access. They are better for 3D, but lighter hunting they would work, like whitetail, turkey, and similar. There's also a "hunter" version that is a little beefier, but still much lighter than the Access.

Outside of increasing draw weight, maybe give that a try

Like many others have said, keep it simple. Assuming your current arrows are properly spined and your bow is tuned, screw on a Slick Trick and see how it shoots. Then go kill a bunch of animals and adjust based on your results. Most of the world's best couldn't tell you what their FOC % is.

1 move your anchor point to the back of your neck


2 buy a PSE full throttle in 70 lb, 80 if they make it

3 shoot fast






Or 4, just shoot what you got and don't worry about it it'll be okay
