Any brilliant ideas on how to make them last longer? I had 3mm conflute that was more plastic and would heal-up to a pinhole. Now Corflute is too brittle and punctures a hole like cardboard.

What centres are you putting on? Paper or vinyl stickers? The vinyl one las a lot longer

I didn't know about the vinly one. Where can one obtain these.

You could try rubber. What is used to repair ets.

Never seen that rubber. Can you buy it from Bunnings?

Some ET manufacturers supply their own rubber. We use the off cuts after repairing the faces. Alternatively you could try Clark Rubber or maybe Bunnings.

We stick used rubber to the back of the corflute centres, using contact cement, so we can stick/sprayglue new paper faces over the top.

I read somewhere one club sets the zero a minute or so high and this preserves the centre

We've had et's for many years now and tried different ways for the centres
Mainly circle cut centres, about 350mm in diam, and stencil on 5, 6 and super rings.As we have, on most Saturday's, 16 to 20+ shooters, the centres did not last a session, the corflute held but the stenciled rings would disappear
How we do it now,
Cut 350mm circle out of aiming Mark.
Attach a larger piece of felt, light grey stuff from some Bunnings stores and is "fluffy" on one side to the back with high strength Velcro
Cut 350mm corflute circles, black from Bunnings, fit vinyl centres over the top
Attach Velcro to the back so that it will attach to the felt
This is easily removed and replaced with a new one during high use sessions. The centre now last ussually 3 sessions as opposed to 1 or less sessions.
Tried the membrane rubber but is heavy and hard to get anything to adhere to it.
I hope there is a better way, someone may have ideas on how to improve on the way we do it.

On a another issue but related to target centres where is everyone sourcing their target centres that have the scoring rings that are within spec as per the SSR's. All the ones that our club has been able to obtain from the usual sources have lines that are much thinner than that specified.

Our club has put a vertical 200mm offset on our ET’s much like Tim mentioned. You end up with a large hole above the aiming mark, particularly at the shorter ranges but the X and 6 rings are still visible.

To give you an idea of what that means at the various distances a shot scored as an X passes through the target above the centre by the following amounts.

Distance(m) MOA MILS
300 2.25 0.7
400 1.75 0.5
500 1.50 0.4
600 1.25 0.4
700 1.00 0.3
800 0.75 0.2
