Hi guys I've picked up my new bsa ultra se today in .22 calibre and I'm looking to get out tomorrow and have a play with it, I haven't used one for years so there's a few things I'd like to ask about zeroing the scopes and filling it up. I'm looking to zero it at 25-30 yards, it says on the gun the max fill pressure is 232 bar but I've read that I'd get the best out of it filling it to about 200 bar, at what pressure would be best for me to zero my scopes at? Thanks
