Minsterley is ok have used it for some load developement,
Only able to shoot at 100m max but if you go in the week
you can end up there on your own.
Cost £25 per day last time I went plus you need to have or buy a backing board plus take a staple gun with you if you have one.
As for Diggle excellent range but you need to be a member or have ranges
on your FAC then you can shoot in the competitions. Not what you want to do,plus it is a 3 month probation period minimum.
Need to build a load for some 140grain bullets,if I go to Minsterley in the next few weeks you can catch alift. I would probably go midweek though,live Stockport side of Manchester.
