Congrats on your kill Gill-T. Sounds like you hit right where you needed to. I know lots of people love those Slick tricks and they really fly great for the guys with speed bows. As far as Ashby's recommendations for "bonebreaking penetration" they don't match his model. They aren't a "Cut on contact tip", The mechanical advantage of the incline slope of the blades are really steep, "Some of the steepest" and 4 blades are way harder to get through bone than 2. These 3 characteristics could have had some influence of not making it through the other shoulder. Just food for thought. Glad you put meat on the table.

Think of it more aggressively and it will make sense. If you screwed a brick on the end of that arrow and still tried to shoot/accelerate it fast out of the bow, that heavy weight would resist movement , the arrow would probably flex so badly that it would break. With this in mind, this is why when you put a large amount of wt. up front, you may have to stiffen the spine of the arrow. On a sadder note most of the arrow charts only go up to 125gr choices on their spine charts. I do "comparison shopping" of their charts in regards to how their charts bump you from one spine to another as broadhead wts. change and make a guestiment of what spine will be needed when going from a 125gr to a 225gr. With quite a few people seeing the light in regards to the benefit of heavier arrows and ultra FOC arrows, it wouldn't hurt the arrow companys to make their charts to cover broadheads up to 325gr.

I use the AMO method #1 from this calculator! http://archerycalculator.com/arrow-front-of-center-foc-calculator/ And here is some great info on the benefits of a heavy FOC for flinging fixxedblades in hunting and windy conditions. Lots of good reason to load up the front. Always keep in mind when you put all the wt. on the front you will most likely have to move up to a stiffer spine. http://archeryreport.com/2010/09/arrow-foc-basics-calculate/

Sounds like a good set up justtracytrollin! I am all bumbed out. My lower back went out Wed. Morn and I missed last 3 days of work. Getting better now. My try the bow again tomorrow. Good luck fellas and shoot straight!

These are what I've chose for this year! Here's the pics of the steelforce traditionals. Total arrow pkg. wt. 535gr. Broadhead 225gr. AMO FOC 20.5%. These fly like a dream out of my Mathews Monster M6 with M7 modules on it and my Mathews Switchback XT! You can only get these heads at 3 rivers archery!

After testing this weekend my final choice is a 225gr. steelforce traditional 2 blade attached to 300spine Gold tip hunters. I think it ended up at 530gr. total. These 3 to 1 slope heads are single bevel rh twist and compliment my vanes in flight. I seem to have no left/right flyers even when punching the release. It's everything Ashby asks, to include cut on contact, tanto bone busting tip. The only thing it doesn't have that Ashby requires is being made one piece. The FOC is Ultra, The heads twist through the animal/target for longer wound path.I can feel this when pulling arrows from target. In the wind at 50yrds they shine through. They even hold a flatter trajectory than an arrow of same weight distributed throughout the arrow and I have no explaination for it. And it's a lot. Like 2.5 inches less drop at 30yds. I'll post a pic or two tonight. The trajectory is acceptable in both the Monster and Switchback.

Wow Kevin! You kick butt in everything! Very skilled sportsman right here fellas!

It never hurts to understand the wiring of the switch and carry an alligator jumper or 2 on the boat with you so you can jumper a ball back to the surface. Power trim and many other items can be jumpered out as well so long as you have them with you.

I shoot Magnus 150gr out of a Mathews switchback and Mathews Monster. Monster required 300 spine where the Switchback was fine with 340 spline. The Paper tune has to be right though with the Monster. They both shot 100gr Magnus Stingers as well.

If you are very frugal and it needs a switch, I bought my switches for 1/2 price at a local electrical/ electronics store called Unicorn electronics. They are referred to as a motor reversing switch if I remember correctly!

Nice going!

I just shot 2 combinations last night. One was 462gr at 70lb out of a Switchback XT and the trajectory is totally fine out to 30 yrds. Same pin in other words. The other combo was 612gr out of a Monster at 68lbs. This too was good out to 28 yrds. Talk about sinking an arrow. both of these is with a quite heavy FOC which when you read Ashby's data is where you want the weight. He builds Ultra FOC arrows way out of scope of what is suggested in all the charts you'll read. If you think about it, the wt at the forward end will create more penetration than distributed through out the arrow. Example being hitting a short punch/chisel verses a long one. Though Kinetic energy and momentum play an important role in gauging things, the fact that resistance to penetration goes up exponentially as velocity increases should lead us to gain the kinetic energy and momentum more with mass than velocity. One cool comparison is by shooting a 700gr arrow in to a gallon jug of sand at lets say 190ft. /sec. It will go all the way through . Now shoot a 357 mag in to it at 300 gr and 1100 ft. per sec. The 357 has way more KE and Mom. which is derived more from speed than mass. It doesn't make it through.

Nice job.

If you read all of Ashby's data, it leads you to a 550 gr. arrow package min. This will get you through Shoulder/ Scapula "WEBS and ball",and the Humerus and sternums!! The scapula/shoulder is easy to penetrate as long as you don't hit the Ball web which is right there, and it's easy to accidentally hit it in your kill zone. Even worse on 3.5 yr olds and older. The bows love the heavy arrows as well. They are much quieter and a little bit more power is extracted from the bow as well. It's very hard to sell this approach to people as it is not main stream and the mechanicals do massive damage when they get inside. On misplaced gut shots I favor mechancals because they cut such a large swath, the deer hemorrhage out. Like I said earlier this data is to get you in to the vitals and out the other side for easier recovery when things go "WRONG" not when things go right. To those who have been shooting deer for 20 plus years, a 550gr arrow out of your modern bow will still be quick compared to your old setup from 20plus years ago. I am just passing this info on, as a lot of people have not even heard of Ashby. Many will dismiss it after a few minutes of reading because they will say it's for African game. Use what you want and are comfortable with.

I am surprised that no one thinks they are just running late. With the cold winter they may stage in massive numbers in 2 more weeks and the hords of fishermen won't be out there to show it because they will have put their boats away. I don't know if this is the case but maybe it could be part of it. What do ya think?

Dr. Ashby has the most valid approach. Why make your set up for when things go right, build your set up for when things go wrong. Going right = nice shot placement, minimal quartering. Going wrong = poor shot placement, hitting shoulder web, aggressive quartering causing arrow glance. Fixxed blade, heavy arrow is key. Very few people are utilizing the great technology in power that the modern bows have to send a bone crushing heavy fixed blade at their quarry, instead they all go for speed, flat trajectory, poor penetration, and poor performing mech. broadheads. Poor performing on heavy bone and glancing shots. If you don't know who Dr. Ashby is and you bow hunt, I suggest you read some of his data! BTW I have shot 14plus deer with Mini blaster 3s mech. in the past, 2 got away because of glancing on a heavy quartering shots. 2 was enough for me. Bulk up and shoot a quality cut on contact fixed blade
