how do the bullet tip arrows work are they supposed to blow up on impact cuse theres no spark or hammer to ignite the bullet to fire

 John,
they are used like just any ordinary point - as jacket for the front end of the shaft - no explosives included here ...
On cheap arrows you may sometimes find alum jackets crimped on. Think of a full metal jacket instead - thats all.

No those are just hallow bullet jackets no lead no powder.They were crimped onto the shaft and used as field tips.bd

here's a pic of the inside.bd

hey one of you zwickey pro's help me out with these.I forgot I had these left over from the old broadhead collect days.Would one of you be so kind as to help me out.How come one does not have the hole for gas venting for cementing ? not a zwickey ? thanks dude's you rock bowdoc

whoops I forgot to move the pic...bd

Doc,
telling the Zwickey's appart will need close inspection and some measurements from a caliper. But to give at least a little opinion, all pictured are Zwickey's. The easiest to determin this way are the two with pin holes.  Most likely they are 5/16 Eskimos from about 1942 (#1401).
All the rest probably made after 1947, due to the shoulder (trailing edge) being about .40" from the ferrule ends. On the pin hole models this same distance is noticably smaller, right?
The Delta looks like the 1959 model (#1426) to me.
An other thing to look for are the different positions of the ferrule tips in regard to the back end of the tripple laminate - and the width of the later. Difficult to determine ...

I have absolutely no idea about the field point  

Thanks Falk good info to know.Yes the field tip is stamped zwickey 11/32 it was with the others hidden away the last several years.Not sure of its age.bd

here's another broadhead I really liked.This is one of the few broadheads I shot a critter with that was not a bear razorhead.A 1953 Glenn StCharles Mickey Finn.I killed a black bear up in Que'bec in 2004 with it.I had it mounted on a Bill Sweetland forgewood arrow weight in at around 650 grain.pretty cool broadhead.bowdoc  

this is a cool old Ben Pearson self knocked arrow I have.

and then.bd

I really like the Mickey Finn. If I ever get the chance, it is one of not to many heads which I would take from my collection and shoot a critter with.

But here is something different and special for you
 

I wish all of you history & collecting nuts a nice and relaxed winter solstice time!

Falk

With the amount of broadheads as I have looked at my little brain could have never come up with that.
A winter wonderland I can relate to ! A very merry and happy holiday season to all.
                           Thanx, Shep

The pic is now my holiday computer background

Here's a really unique field tip.During WW-2 there was no steel for tips it was all used for war machines.Some field tips were made of a real hard white plastic made to look some what like bone or ivory.Kind of neat..bowdoc

Falk very cool and a Happy Yule to you as well.

Bowdoc I have lots of walrus ivory if you'd like one made from the real mccoy.

Rick man I would love to have just enough to make one tip for a cane arrow a friend made for me.
I scored a couple plyflex solid fiberglass hunting arrows last week.These are 1/4" weighting in at a whopping 580 grains with punched(no glue)field tips and are super straight pretty cool..bowdoc
