His target weight was 575 gr total with a 150 gr head used.
We can look forward to some field reports and photos of holey hogs killed in Spain soon.
To achieve a 425 grain arrow (without point) I selected the following components and went to work.
- 18" Zombie shaft .001
- 110 grain brass insert - Knurled.
- 60 grain add a weight.
- .296 inner carbon tube.
- 10 grain BE nock with a 18 Grain add a weight to duplicate the a 28 gr Lumenok.
- VaneTec 3.15" Swift fletching used. ,
NOTE: all white fletch was chosen . A black ink mark notes the channel or down fletch position.
The Inner carbon tube adds significant front end strength and reduces/shortens arrow flex when released from the string ( straightens out sooner due to reduced flex).
Additionally , each shaft was spine indexed and weight matched uniformity fell with .5 gr +/- , not too bad the way I see.
Shaft ends were squared and the final brass insert was squared to run true.
Actual finished weight was 428 grain without point giving a 578 grain total weight with a 150 grain point.
Who remembers the 2004 Comedy " Meet The Fockers" with Robert De Niro , Ben Stiller, and Dustin Hoffman? We watched it again this past weekend which gave my thread idea today.
