I recently started trying out Eley ammunition. They have many cost categories in the .22LR cartridges (I don't know if ELey makes anything else.) What I've been able to get locally is Benchrest Precision, $15.00/50, Match, $20.00/50 and Tenex $25.00/50.
I haven't shot the Match or Tenex yet.
I figured the more expensive is "better". Definitely the Benchrest Precision has been better than anything else so far in my CZ-455. We'll see how groups develop with the more expensive Match and Tenex.
But my question is, what do they do to make the difference in price between them? Is it better quality components, such as powder, priming compound, bullets and cases? Or just basically the same components with much tighter tolerances of the amount of all these components?
I noticed the bullets for both the Match and Tenex seem to be the same, but different from those on the Benchrest Presicion.
Also, tolerances for rim thickness were tighter for the Tenex than for the other two. Out of 50 Tenex measured ALL measured were the exact .042" rim thickness, where the Match had 3 or 4 (out of 50) with slight variances up or down of .0005" or so. The Benchrest Precision had slightly bigger variances, to the tune of .001" (.041" , .042", .043") again for 50 measured.
Cheap ammo, Aguila, Federal Auto-Match, had more rim thickness variance (.041" thru .044" ) but sorting by rim thickness had no measurable differences.
The cheap stuff gives me .700"-.750" four, consecutive, five-shot 50 yard groups. Eley Benchrest Precision has given me .365" in the past, but lately I've been getting more like .440" or so. Tenex and Match still to be shot. Maybe I've reached the limit of what is possible of myself and/or my equipment. We'll see once I get to shoot the Match and the Tenex.
I'm shooting a CZ-455 off a Harris bipod and a rear bag. Leupold 6-18X, and a Yo-Dave trigger kit. Very solid bench. No wind flags, but mostly no wind.
Opinions?
