New To High FOC

High FOC Arrow Builds - Helpful or Hype?

Increasing the FOC of your arrow and broadhead build is one of the easiest ways to see an instant improvement in your arrow's efficiencies of both flight and penetration. What? You don't believe it? Good! 

Don't believe everything you hear or everything you read for that matter.  

Do your research. Test things out for yourself. Don't fall for marketing hype, prove to yourself what works and what doesn't.

Here at GrizzlyStik, we built an entire arrow and broadhead system based on the amazing eye-opening test results and reports published by Dr. Ed Ashby many years ago. 

First, we created an arrow and broadhead system that followed all 12 of the penetration enhancement factors identified by Dr. Ashby. Then we tested our arrow and broadhead system in actual bowhunting situations in the field because, after all, arrow lethality is what we were after. 

What did we find? It worked! All the bowhunters, all of them, were amazed. Professional hunters in Africa had never seen arrows do this kind of damage before. Guides and outfitters in North America were shocked to see bowhunters getting through moose and elk shoulder blades. Serious bowhunters all over the world were amazed at the penetration and performance they were seeing! GrizzlyStik was on to something - something big.

A killer arrow and broadhead system is what bowhunters all over the world needed. Bowhunters were wounding and losing way too many animals. Even on whitetails, bowhunters weren't even able to get arrows through the shoulder blades of these fairly small animals. 

The end result we called the GrizzlyStik System. The GrizzlyStik arrow and broadhead system provided the arrow lethality and performance that put big game animals down for good - even when things went wrong.

Now bowhunters didn't have to fear the bone. They could focus on the path the arrow needed to travel to reach the vitals and take the shot.

Now complete pass-throughs became the norm. Bowhunters expected pass-throughs and they got them. They expected to get through heavy bone, and they did. They expected to kill the animals they shot rather than wound them, and they did.

How? Seriously! What the heck was going on? Heavier arrows, higher FOC percentages, single bevel fixed blade broadheads. How could these arrow and broadhead builds be so much more lethal than what most of the bowhunters were shooting?

Heavy arrows with FOC percentages aren't exactly new, in fact, they can be documented all the way back to the beginning of man. Lucky for all bowhunters today, Dr. Ashby of the Ashby Bowhunting Foundation spent over 30 years researching and documenting arrow lethality and penetration. What secrets did the good doctor find?

 Dr. Ashby's top 12 arrow penetration enhancement factors

1. Structural integrity

2. Perfect arrow flight

3. Arrow FOC (forward-of-center)

4. Broadhead mechanical advantage

5. Shaft diameter

6. Arrow mass

7. Blade edge finish

8. Shaft profile

9. Broadhead/shaft silhouette

10. Type of edge bevel

11. Tip design

12. Arrow mass (650+ grains) above the heavy bone threshold

Over the past decade, GrizzlyStik has designed a killer arrow and broadhead system that has proven itself in the field on literally tens of thousands of big game animals. We accomplished this by closely following, addressing, refining, and then building each of Dr. Ashby's 12 penetration enhancement factors into our deadly arrow and broadhead system.

Still think it's just high FOC hype? Fair enough, but we encourage you to test it for yourself. Prove it to yourself. You don't have to take our word for it, as a matter of fact, we don't want you to. We want you to see for yourself. We want you to start getting reliable pass-throughs on your broadside shots even if you center punch big ribs. We want you to watch your arrow blow through that elk's shoulder blade and put that bull of a lifetime down for good. We want you to make the most of every bowhunting opportunity you get on your hunts. You've worked hard. You've got a lot invested in every hunt you go on. It's time to shoot an arrow and broadhead system that puts the odds in your favor. It's time for you to incorporate all 12 of the Ashby penetration enhancement factors into your arrow and broadhead builds.

Hype can't drive an arrow and broadhead through a Cape buffalo scapula and blow out the other side.

Follow the Ashby rules – and you will enjoy much more bowhunting success.

Get out there and prove it to yourself.




If you're new to GrizzlyStik, this is where you should start.

 

We know you have lots of questions..... we always do our best to address the normal why-how-testing questions we get every day. There's a mountain of information here at GrizzlyStik but if you're new, there are some things you should know about us before you dig in.

We've been a family-owned business since 1994.

As arrowsmiths, we feel a heartfelt duty to the animals we hunt. We believe it's our responsibility to build equipment that increases the odds of all bowhunters killing their big game animals as quickly and cleanly as possible.

For over the past decade, we have been continuously refining our arrow & broadhead system following Dr. Ashby's top 12 arrow penetration factors.

We're all customer direct - if you have questions you can talk directly to the manufacturer.

We strive to give world-class customer service - we would like you to think of us as your personal arrow concierge.

Bowhunting is an imperfect sport. All of our equipment is built with the thought to help you be more successful.

This site has various documented post-mortem reviews and pictures. We've done this to educate and inform bowhunts want is actually happening in the field.

We don't want to just sell you something, we want to give you as much information.

He have found a direct correlation between high FOC arrows at or above the heavy bone threshold and VERY happy customers.

We like to recommend you shoot the heaviest arrow possible, with the highest FOC - but it has to do two things

  • Fly perfectly from your bow
  • Fly at a trajectory you can live with out to your maximum lethal distance

 We're not always right but we're seldom wrong.

 

 

 




Performance all bowhunters should expect......everytime. A GrizzlyStik Momentum arrow built to 650 grains total (24% FOC) tipped with a Silver Flame 200 XXL broadhead powered by a 70# bow. Full broadhead penetration after hitting the near-side scapula and then breaking the off-side humerus bone.
