I have well over 1000 acres if you want to give it a go. I also have a few other places where I have permission to shoot anything any time of year, so that probably easily adds another 500 acres or so. You are welcome to use rifle, shotgun and anything else you fancy. There is woodland, open fields, grassland and all sorts.
You can shoot rabbits, pheasants, partridge, pigeons and anything you fancy eating, with the exception of hares, as I like leaving them alone.
I went out for a few nights about 3 weeks ago and knocked off about 300 rabbits with shotguns and rifles etc with a few mates I invited over. Got some lovely pigeons too.
Only problem is that although I am well within the 25 miles, I live on the Isle of Wight, but you are welcome to shoot with me. I quite often disappear for a few days up around the place and just set up a camp and "bushcraft it up", eating what I shoot etc. Am happy to do some kind of return favour if you want. The night shooting for rabbits is great and I have different terrain so you get a really good variety of hunting and it definitely hones your techniques!!
If you want anything local, find a few local shoots and sign up as a regular beater and ask the keeper if you can also ping off a few rabbits etc and maybe some pigeons through the summer. Most are fairly obliging unless they are already oversubscribed with people shooting vermin.
