Maybe in the wrong section of the forum but I think I am close. Geelong Rifle Club is about to put in an order for Corflute sheets about 6'x6' or 6'x8' for our targets. The minimum order is 250 sheets at about $6 or $7 each. We can handle the order but it will mean that we will have stock sitting in the shed for a long time. Is any club interested in piggy-backing on our order so that you can take some off our hands?
Otherwise, has anybody out there found a more convenient and cheaper source of Corflute sheets?

Source is Dandenong and sheets will be delivered to Geelong at GRC's expense.

Cheers

What gsm and thickness? White with UV? Price for 8' or 6' widths? (you can mix order). Do you have a firm quotation? James

James,
No answers yet , just searching out the interest. We will buy another 250 sheets as per Kongsberg specs. as we did last time but I am still chasing the details as personnel have changed.
You have registered an interest. Saves me contacting you direct.
Cheers
Peter

What thickness is the sheet
This price sounds very cheap to me
Sure its not a sq metre price?
If that is the price per sheet thats very cheap
Cheers

My thoughts too

Well, I should never rely on other people's memory.

2380X1800 5.0mm, 90gsm, UVstable, white @ $30 per sheet (GST inc)

Sorry for the confusion.

Would think you require 2400 x 1800 as per NRAA target size? And either 5mm x 1000gsm or 6mm x 1200gsm for this size panel. JC

James the dimensions are fine for Kongsberg targets given the manner in which they are constructed. You still get a 6'X8' target and scoring area. If there was interest from others we could go to 6'X8' sheets and then we would trim them.

We have worked with these corflute sheets from this supplier over a few years and sheets of that size have never caused a problem. They are backed by the rubber and are supported on all 4 sides so they are more than adequate even in our winds.

Perhaps unnecessary cost?

You may get a 6 x 8 target but do you get a 6 x 8 scoring area? NRAA SSR's say the latter, JC

I think you misunderstand me James.

The target has rubber front and back to provide the acoustic chamber. The Corflute is just the front and backing piece that provides the waterproof covering and a surface to stick the aiming mark on. We also use cardboard as a replacement for Corflute. Because the Corflute does not bend or flex in the wind, due to the rubber at its back, we can get by with a lighter sheet of Corflute or cardboard.


I haven't measured the internal dimensions of the acoustic chamber but I have no reason to believe it isn't 6'X 8'. It does extend past the sides of the Corflute a little bit. This is of course hidden under the plastic external wind shields on the side which extend over the edge of the Corflute. I can verify that shots which go through the wind shield but just miss the Corflute do register with their position.

Why not use the Corflute as the acoustic chamber, much cheaper, JC

Not possible.

The shots blow holes in Corflute and so you lose the integrity of the chamber. The rubber allows a bullet to pass through and then the hole closes over so your integrity is retained.

Maybe we need a system like the Haring target where the acoustic chamber is done away with entirely. More development is needed here.

Have you actually tried it?

Not as such, but we know from bitter experience that if we let our targets go beyond about 3000 rounds without replacing the rubber they will malfunction. Any temperature variations across the chamber are the death of the targets and wind blowing through holes will cause temperature variations. When that rubber starts to get holes bigger than pinhead size then we are in trouble.

Corflute also splinters and there is a possibility of shards falling across the sensors and again affecting operation.
