Looks like you are shooting in a rented village hall. Our club did that for about ten years on and off until we built our own 'indoor' range.

What distance do you have? If you can get 20 yards then you could include lightweight sport rifle as well as bench rest in your list of disciplines. The Hammerli rifles look like they are 7.5 joule versions for 10m match shooting.

Regarding funding, have you met your local councillor? You may be too late for this round of grants..https://www.llandudno.gov.uk/en/grants

Maybe Conwy Borough Council has something similar? Councillors often have discretionary funds they can award to deserving causes in their 'parish', so to speak.
