Just had a look at the brocock & bsa ultra on YouTube, both look handy little rifles. I like the cocking action on the BSA looks like a good mechanism, think its between ultra & s200 as don't see many brococks for sale. I already have Simmons wtc scope & hatsan pump so just looking for something for shooting woodies & vermin, what are these like for services, seals etc anyone had any problems with them?
