I am new to the sport (just over two weeks). I got a 1000 hull comp x with my gun. Is this a good cartridge? I understand it's their entry level product but at this stage will I benefit from a better product? The guy in the shop said the lyvale power blue (that my friend shoots). Is £30 more a thousand. I know that's not much diluted over a 1000 but he said you'd be better spending that £30 on a 100 extra clays at the moment. Thoughts please
