My Bow

Recently, one of my Tumbler followers asked me to share the details of my competition bow since they were moving towards competitive archery and wanted to know about my bow. First, I will explain the story of how I got to my current bow.

I have been searching for the perfect bow for me since the day I started shooting. Finding the perfect bow takes experimentation, trial and error. Your bow is a personal preference, so much so that in ancient times, it was a person’s most treasured possession and many kings were entombed with their bows. Finding the perfect bow may take years… and it may change as you grow, change and develop.

When I was just starting out at 9 years old, I needed a light mass weight bow. Something that would not damage my bow arm long term however would allow me to practice a lot. I was a good shot however VERY small for my age. I was able to come across the Fiberbow riser with a mass weight of only 599 grams, less than half the weight of other bows and it allowed me to practice a lot with less fatigue. This was a great bow until a couple of years ago, when I became stronger than the bow.

So before training for the Canada Games, I switched to the Cartel Midas 25” riser. I love that bow, it helped me win a Silver at the Canada Games and it took me to the World Indoor Championships in Las Vegas . This was an awesome bow for me as a cadet, however, with the change of divisions and greater distances as a junior I need to generate more power for outdoor shooting. Therefore I switched to a 23” Midas Riser and increased my limbs to 36 pounds. On initial tests I was able to top 196 feet per second and had to add additional weights to consistently settle on 194.5 fps. This is high for a recurve archer with only a 25” draw length.

My new bow is as follows…

• 23” Cartel Midas Riser
• 36# MK Archery Medium 1440 limbs
• Cartel Spectra Sight
• Cartel XD Stabilizer system with Midas V-bar
• AAE Extended Clicker
• Cartel Rest
• Cartel Cushion Plunger
• Custom String

Wow, this bow is amazing; I hardly feel the shot. The limbs are the smoothest I have ever shot. The limbs use carbon foam-core technology and are extremely smooth and straight. I love my new bow and it is the perfect bow for me right now. Although bow selection takes time and experimentation I hope you too can find the perfect bow for you.

Archery Ballistics

Recently, I invited you, my readers, to ask me any questions you have about archery and you responded. Over the next couple of blogs, I will try answer all of these questions to the best of my ability. I decided to answer the one I know the least about first. Although I am not into hunting, I am not against the practice if you are going to use the entire animal. Also, in my opinion, an animal deserves a quick humane kill and not left just wounded walking around in pain. David Roberts asked…

I’d be interested in seeing your take on ballistic; specifically focusing on achieving maximum momentum (e.g. A lightning fast arrow with the weight of a feather vs. a slow moving heavy clunker). Are there any equations for calculating the “perfect” arrow for inflicting the most damage on its target? It would have to involve the power of the bow, the weight of the arrow and the relation between the two. Is a 400 grain arrow traveling at 300 fps more damaging than a 700 grain arrow at 235 fps? Less?

For target shooting faster shots means less drop & better accuracy, but for us archery hunting folks a “perfect” arrow is one that is has the exact weight that will provide the most possible momentum of that arrow. You go into a sporting goods store and you see all the arrows advertising super light weight and giving performance metrics in the amount of energy that they transfer when they strike. That metric is the wrong one to use when looking for a damaging arrow. A damaging arrow doesn’t want to put x amount of kinetic energy into a target over the course of 2 inches, it wants to put x amount of kinetic energy into a target over 3 feet. Momentum calculations would pr

ovide that. I understand that you’re not really into the hunting with archery (I think?) and that this topic isn’t really beneficial to competition shooting at all, but for real world applications of archery it’s one of the most important topics around.

My understanding is hunting is about the kill and understanding arrow flight will help you make the most of the opportunities that are presented while in the bush.  There are two planes of accuracy that you need to be aware of; Horizontal (left – right) axis and Vertical (up – down) axis.

The horizontal arrow flight is managed through good proper form and the understanding about the effects of nature elements such as weather conditions. Check out my earlier blogs about the various effects.

The vertical arrow flight is tougher since all arrows fly on a parabolic course. Frequently misses are high and low since it is hard to judge the arc of your arrow flight for unmarked distances.

Parabola in mathematics, a parabola is a conic section, created from the intersection of a right circular conical surface and a plane parallel to a generating straight line of that surface. Another way to generate a parabola is to examine a point (the focus) and a line (the directrix). The locus of points in that plane that are equidistant from both the line and point is a parabola. – Wikipedia

Example. If you kick a soccer ball (or shoot an arrow, fire a missile or throw a stone) it will arc up into the air and come down again …… following the path of a parabola! (Except for how the air affects it.) – Math is Fun

Some bow hunters choose to use a 3-pin sight so they can guess better. By pre-sighting distances of 20, 40 and 60 yards as examples, it allows them to better judge the best impact for the kill zone between these sight marks.

Ballistics is the science of mechanics that deals with the flight, behavior, and effects of projectiles – Wikipedia.

Since the question is specifically about ballistics, understanding all components of a hunting arrow will help you select your “perfect” arrow configuration. There are a lot of variables to consider, here is a list of things to consider, I found on the following website…

• Shaft size (diameter and wall thickness)
• Shaft length (+/- 3⁄4 to one-inch can significantly change shaft stiffness)
• Weight of the broadhead to be shot (+/- 25 grains can significantly change shaft stiffness)
• Draw weight of the bow (+/- 2.5 to five pounds can significantly change shaft stiffness)
• Archer’s draw length (certain shafts become significantly weaker when cut past 28 inches)
• String material (Dacron strings are slower and require a slightly softer arrow, for example)
• Type of bow (recurve or compound with a wheel, soft-cam or speed-cam)
• Finger or mechanical release (finger shooters require a slightly stiffer arrow)
• Bow length (bows less than 40 inches in length require a slightly stiffer shaft)
• Overdraw length, if used (three-inch-plus overdraws require a slightly stiffer arrow)

You can review my Arrows – The Series for details about most of these.

“Faster shots means less drop & better accuracy” is true for all archers. Since, for example, at 150 fps, there is an 8” drop in trajectory at just 10 yards versus only 5 inch drop at 200 fps, there are benefits to maintaining a higher velocity. This allows you to shoot from farther away and better judge the curve; giving you more opportunities.

To continue, assuming all things are perfect, longer draw length or heavier draw weight should produce higher kinetic energy, momentum, and velocity that will result in deeper penetration. It also offers more choices in selecting your broadhead. My understanding is for small game, where penetration is not the issue you can use field tips. However for larger game and for a quick kill you need the proper broadhead choice as well as the proper arrow selection. Since, the weight of broadhead is the ballast of the arrow, and when we are talking about hunting you may need to start here.

A broadhead weight can range from 85 grain and can be more than 140 grains and the number of blades is important since more blades increase the wind resistance causing greater dive. I am not an expert about broadheads however I know you can select from various types including fixed blades and mechanical blades. You can also check out this video I found about types of broadheads and this website for the pros and cons of each. I also ran across these two websites about penetration of various different broadheads. (Wibowhunters and Bowonlyoutdoors). Once you have selected your style of broadhead, you can properly select the arrow to match your bow to maximize your velocity and penetration.

If you really want to understand the technical details of an arrow ballistics, arrow parabolic course and the calculations; check out this website. However I am not a math major and If you are like me that is far too technical. So for specific arrows and bow configurations including total momentum, there are several options available including online ballistics calculators such as Outdoorsden OR Peteward. You can also purchase highly rated archery applications such as The Archery Program Pro by Tony Virnoche and OnTarget!2 Software for Archers by Pinwheel Software that provide more than just ballistics information. Lastly if you are mobile user there is a phone/android application called Archery Ballistics that you can carry around with you to the sporting goods store to help you make your selections.

Remember every setup is different and changing even one thing can effect everything else. You will need to spend time with the calculators and trying various combinations until you find the right one for you and your bow.

Although, I am not into hunting I hope that I have been able to answer your question and provide some high-level direction.

Drying Feathers

Now that we are in the outdoor season there is an opportunity to shoot in all kinds of weather. Weather itself effects the way we shoot, and you can read my earlier blog about different weather conditions and their effects on shooting. As competitive archers, we love our equipment. We have invested time, money, and countless hours in finding the perfect setup for us. So,once the tournament is complete we need to care for our equipment. We need to have our equipment in perfect condition for the next tournament.

Perfect shooting conditions rarely require additional maintenance, however not all tournaments are shot in ideal conditions and rain has the potential to do the most damage if not dealt with immediately since metal rusts, wood warps and fletching matte.

Once out of the weather, take the time to properly and thoroughly dry all your equipment. Using a clean dry cloth, wipe down your limbs, riser and stabilizer. Carefully dry your sight making sure not to lose your sight marks or damage your scope. If you use a spotting scope or binoculars make sure no water has damaged or fogged up the lens.

Finally, carefully dry your arrows by wiping the shafts dry. Plastic Vanes can be dried using a clean dry cloth however feather fletchings will need to be air dried so that are not squished. If your fletchings, plastic or feather, are matted, you need to open them up again and allow them to air dry by following the following guide:

How to dry your feathers

You will need: your arrows, a pot, water, and an oven/stove

• Fill a pot with water and bring to a boil
• Hold each arrow’s fletching over the steam
• Patiently wait for the fletching to start to open up. Remember the fletchings will open the rest of the way as they dry.
• Place the arrow in a clean dry spot with the points facing down until dry.
• Repeat for all your arrows and turn off the stove.

Taking the time after a rainy tournament to attend to your equipment, can save you money and grief.
