Excessive headspace?

I’ve noticed both my SMLE and No4 leave a shiny ring above the casehead. Is this normal? Could this be excessive headspace? Neither rifle will fully close no my ‘no-go’ disc gauge. Ammo is PPU 174gr.

EDIT; I tried the ‘hooked wire’ test for casehead separation but insides of the cases feel smooth…

Is it normal for site staff to ‘test’ eye protection by shooting at it?

Brought my own eye protection (mine was Bolle X1000 vented) to my second airsoft session and was informed that ‘non-rental’ eye protection had to be ‘tested’.

This consisted of the glasses being placed on the ground and shot from a couple of metres away with some powerful sniping rifle (don’t know make/model).

Staff member took one look and said something to the effect of ‘made in Taiwan; better test it’. This seems strange as even a noob like me knows that Taiwan produces loads of good quality airsoft gear.

The ‘test’ left a dent directly in front of my right eye when worn. Not only has this degraded the quality of vision through my new £70 glasses but also, according to the manufacturer information, requires the lenses to be replaced.

Anyone else experienced this?

Edit: They were perfectly happy for me to use the glasses after they ‘proofed’ them by damaging them…
