Hello rm,have a look at Yorkshire Smallbore Shooting website and select comps. BR, for the league rules, NSRA rules are the same.
The rifle uses no rear support,butt in shoulder and non shooting hand providing support to the underside,no fancy gear so cheaper!!remember its Yorkshire!
The Yorkshire own design target is inward scoring except when gauging a +1 !!available as 20 yds or 25 yds.cheaper than the NSRA target,its a big league !!!
Your club can affiliate to Yorkshire for a few pounds or you as an individual,summer and winter leagues.
Don.
