Truth be told probably 99% of shooters can only tell a cartridge is of mid or top range because the seller and it's marketing and price tag tell us it's top range. You could take a black gold and put it in a velocity case and the majority of shooters would have no clue of the difference. How do you tell, recoil and breaks?
Yesterday we shot Grimsthorpe, the pool shoot had some good distance standard and midi birds. 3 of us shot it, one with black golds and 5/8ths, one with eley vip and 5/8ths and me with velocity plus and 1/4. My breaks were equally as good if not better at distance than the other two, recoil the same if again not a little less. So where was the difference, brass, marketing and price tag.
The point of my post is, we take the manufacturers word of how good a cartridge is from the big boys, so you have to give George the same benefit. But his come out at £30 a thou cheaper. I will stick with my budget cartidges as I could shoot anything and still miss. But I think George deserves a bot more respect than he appears to be getting in this thread at times.
