PTFE ammunition

I've not seen PTFE balls mentioned as practice ammo so here goes.

When choosing indoor ammo I think the most important consideration is finding something closely matching your outdoor ammo. This means technique developed indoors (like a good pouch release) should be transferable outdoors.

PTFE balls are available in a range of diameters - all the sizes of steel we shoot - meaning you can match your indoors and outdoors ammo exactly. PTFE is a particularly dense plastic (2.2 g/cm3). This means for a given size it has greater weight, not too light, unlike some other plastic practice ammo.

Downsides? Cost. About $2 each. Now, matching bands to PTFE ammo. An example:

A 9.5mm (3/8) PTFE ball weighs 0.99g
A 1/4" steel ball weighs 1.05g

Therefore band suggestions for shooting 1/4" steel apply the same.

To calculate the weight of a PTFE ball you can use these tools:

Gobstoppers are small jawbreakers and guys have used them for all kinds of practice... pick them up at your candy store.

I know the I have used the 3/4" jawbreakers that I bought at Winco for hunting, and on occasion sprayed them with clear paint so they would not get sticky in damp weather.

By the way, these 3/4" jawbreakers weigh between 83-95 grains and at close range hit like a ton of breaks, you just need a good size pouch !! Used them in my F-16's using a Tex pouch ... works great.. looped 1842's, looped 1745's are great for this ammo ---- Single Green Dub Dub sends them out like a rocket !! ... Starling and Pigeons better watch out !!!
