Welcome aboard Barry
If you've got some spare time on Sunday, why not pop along to Redferns to watch the Winter League shoot. Should give you a good idea about what's involved and plenty of people there to give advice.
Just about every possible gun and scope combination you can think of too, so might be a good opportunity to check out some scopes to go on your dommie
There'll be people there from about 7am until about 4pm I should imagine.. first session kicks off at 9am and the 2nd session kicks off about 12.. there'll be a snap van there too...
