Boy I shot some arrows this weekend :shock:
In the past week or so I have stripped my Trykon back to clean the dirt and dust of a years hunting out of it , I coincided the activity with the trial of a variety of vane types and a Carolina deluxe whisker biscuit , once it was re assembled.
I love tinkering with my compound to squeeze the most out of it , A long time ago I settled on my arrow shaft brand and model I shoot Beman ICS-400 Camo shafts after bare shafting them and have normally shot 3 x 5 " duravanes on a Blitzenburger hard Right wing helical.
As I had been testing Vane types I had six set up with 3x5" Duravanes , six set up wit 3x 2.5" Blazer vanes , six with 3 x 4" standard Duravanes
a further six with 4" low profile Duravanes. I used the same Blitzenburger helical clamp on each of the Vane types.
I was most interested to test the claims made on which had the most control capacity over an arrow.
After fundamental tuning that had all vane types grouping tightly (nock splitting vane ripping) together with 125g field points , I started the testing with broad heads.
Of course its normal to expect that modifications are to be made to the arrow rest and potentially the nock point once broad heads are in place and any difference in the point of impact is observed (Can I just add this is the point where many move their sights to the point of impact of broad heads and consider their bow tuned) Its not !
After attaching two bladed broad heads (Magnus Stingers) I shot the first group of three arrows at a double row of 4 20mm dots from 20 metres.
The first group was with 5" standard Duravanes they were at perfect height 3 inches to the left.
The second group was with 4" standard Duravanes they were at perfect height and grouped 4 inches to the left.
The third group was with 2.5 inch Blazer vanes and grouped as the 5'' Duravanes did at the same height and 3 inches to the left.
The fourth was with the low profile Duravane again they were the perfect height but these landed together 4.5 / 5 inches to the left.
After the groups were fired I placed a sheet of butchers paper a metre in front of the target on posts and shot one of each through to the target , I had perfect point to Fletch patterns (or at least nothing detectable in paper tuning signs)
I rested for an hour or so while I had lunch and a drink then shot the second row of dots from the same distance with identical results.
Obviously this showed that the arrow rest had to be moved to the right in order to bring the shots to centre and that 2.5 inch Blazers and 5 inch standard Duravanes have the same controlling influence (still shocks me , but good on them).
Now what interested me was that had I not had the other vane types to compare I would have moved the rest to the right a couple of mm until the 5" standard Duravanes hit centre and called it tuned and it would have been close (but hey !! a job done well is a job well done) it took a further adjustment to the right of almost the same amount to bring the low profile vanes to centre and once done all Vane types landed one after the other on top of each other.
At this point field points and two bladed heads landed into the same groups and expensively sometimes the same spot.
I ended up testing eight 125g broad head types after the tune was complete.
Magnus Stingers
Outback Supremes
Outback Hunters
Tusker Spirits
Bone breakers
Muzzy 3 blade
NAP Thunderheads (three bladed)
First Cut
Each flew and landed in great groups together regardless of vane types.
I took all the arrows out to where I could shoot at 50m and the results were all the same , with one slight difference the low profile and Blazer vanes were consistently a little higher on the target 2-3 inches (less drag)
By being able to view the same arrow and broad head combination shot with varying levels of vane correction I was able to better detect the necessity for optimal tune and make the changes.
And additionally prove to myself that when a bow is tuned down to the wire as you can do these days you can shoot a wide range at front and back.
Beyond that you may wonder "why worry about such small increments of value"
It matters most when you are drawn down on that animal , regardless of breed or trophy potential , your in a right to left cross breeze your on one knee your heart is pounding your not at 20m your at 37m and your waiting for that perfect shot angle to release the perfect arrow.
What did I learn that I didn't know prior ?
The Key point.
By being able to view the same arrow and broad head combination shot with varying levels of vane correction I was able to better detect the necessity for optimal tune and make the changes.
You cant really (safely) bare shaft an arrow with a broad head ,but by shooting one with marginal , or at least less than normal steering capacity in terms of its fletching will act as a tell tale , with great value. I now consider a half dozen arrows fletched with low profile vanes a great tuning asset.
Paper tuning will not show you this slight a correction but it is still there to be made.
A Carolina Whisker Biscuit arrow rest will without problem shoot the Vanes mentioned above without negative effect on the vane and with breathtaking accuracy shot after shot.
The Bow has to my mind never been more precisely tuned , its performance from 10 to 50 is a joy to watch.
Tune with confidence = Hunt with confidence
Some may be interested.
:D
