A rifle 22LR ammo test

He doesn't even appear to have posted the speeds, so having found that Tenex goes through it really well, he can't go and buy more Tenex of that speed.
I have this sneaking suspicion that he's going to start putting ammo of different speeds through his other rifles, which means what little comparability he might have had will be gone. Different rifles, different ammo - you can only change one thing at a time! Basic scientific method!

My understanding from others with more practical experience of batch testing than me is that speed is a red herring. Both in that 2 batches of ammo of the same speed doesn't mean that they will shoot as well as each other, but that also the eley quoted speed is not actually correct.Hemmers wrote:He doesn't even appear to have posted the speeds, so having found that Tenex goes through it really well, he can't go and buy more Tenex of that speed.
Rob.
I'd agree with Rob here. We could take a batch Eley claims at 1054 and run it through Rob's rifle and mine, and we could get an average of 1040 in Rob's and 1070 in mine. Different barrels shoot differently. Eley only uses two rifles for quality control as far as I know and I sincerely doubt each batch gets tested in both, and even if they did, it's not an accurate reflection of how it would shoot in your gun. I don't really have any time for the idea that rifles prefer faster or slower ammo. Ultimately they like whatever ammo they like and the speed is essentially irrelevant (And the debate of slow ammo versus fast ammo in wind has just wasted an awful lot of time better spent with fingers on triggers learning to shoot what people had).
He is also slightly short on sample size (25 shots) to be able to make valid statistical predictions (need sample size of at least thirty).
Assuming he used the same hold for every group shot, the composite size of the total group would be more significant than average group size, as some of the groups with the same ammo brand appeared to be offset in some direction from the other groups.
