Have you found that similar type rifles (No8's for example) have different ammo requirements? This is the case with my two; I assume its down to the wear after thousands of rounds. Although one has the barrel floated all the way and the other has the correct up pressure; both are equally accurate with their preferred ammo.

The Eley Match load is about 30% more expensive than the Eley Team; but it is basically the same ammo. The Team ammo is the batch that falls outside the Match velocity spec. Luckily they print the speed on the box, so when it's a good batch, just a few feet per second outside the Match spec; it's good value.
