I normally use Winchester subs in my CZ452, which I have had no complaints about. Today I picked up some Eley subs from another dealer as my usual one doesn't stock them. I spent a happy hour plinking at targets, pushing the range out. Not a great deal between the two out to 45 yards, but from then on the Eleys took over and at 100 yards they were doing fabulous groups that the Winnies couldn't compete with.
Quite good fun this experimenting to find the best round for your rifle. Some are terrible and some spectacular
