Bullet holes

I normally take a wire of the appr. thickness, heat it and push it through the plastic thus creating a hole.
Touch of NMF around the edges and you should be ok.

It helps if you thin the plastic a bit to make the thickness more to scale.

If you have dremel tool (& if you don't highly recommend getting one they are invauable in modelling), take a grinder and CAREFULLY thin the plastic behind where u want the bullet hole,, then use either an awl or dental pick to poke a hole thru it.. I have also used an exacto #11 blade to poke and then twist the hole creating ragged edges which look great for thin skinned vehicles or metal bodied aircraft ..for glancing blows on armor try using a dremel grinfing bit on low speed and be careful..
Good Luck

Dremals are also good for dents in sheet metal such as gas cans just grind off how big you want it then smooth it out with steel wool.

i use my modeling blade to also poke and twist creating the effect of bullet holes.

What kind of material are these billet holes going into?
what I mean is is it metal? wood? glass?

For metal and wood I usualy get my cordless drill and put it on full torque, this will make it do hot it slightly melts the plastic around the hole.

With wood (only in planks, not trees and such) I snap the piece in half and re-glue it, this is the most effective way of making convincing splinters.

And glass, if its 'bullet proof' but hasn't lived up to its title, treat it as metal, and if it never was bullet proof use the same as wood, but dont snap it, just scour it with a VERY sharp moddeling blade.

I used an old Dremel moto-tool years ago on a wingy-thingy. A very small bit, and since it was black some silver paint. If there is more than one hole be sure to do a good layout or pattern for the round strikes. The higher the rate of fire, the more holes you drill.
