Me too. CCI Standard has been good entry-level training ammo. I shot a lot of it with my Anschutz 1913 when it was difficult at times to get Eley Club in the US. It was accurate, consistently sub MOA, clean and it was reasonably priced, but it was at a significantly higher price point (~$0.10/round) than plinking ammo (~$0.05/round).
HOWEVER, (Thank You
BeeMaa for prompting the check!) a quick Google search shows that its price has apparently dropped considerably and it is currently at almost the same price (~$0.06/round) as the Thunderbolt (~$0.05/round). Now, THAT is fascinating !!!!
I have never shot it at 150 yd but there is no reason why it should not remain around 1 MOA or so, i.e. a heck of a lot better than the Thunderbolt. At 1,070 fps its trajectory will be dropping even more than the Thunderbolt (1,255 fps) but that's OK out to 150 yd or so. The software predicts another 2 MOA of drop:
Thunderbolt - 1,255 fps: +6" @ 50 yd / +7" @ 100 yd / zero @ 150 yd.
CCI Standard - 1,070 fps: +8" @ 50 yd / + 9" @ 100 yd / zero @ 150 yd
Wind will be even more a factor too than with the Thunderbolt at 150 yd, but that is good practice too.
I am going to try it at 150 yd and if it groups around 1.5" at 150 yd (i.e. 1 MOA) for the same price the Thunderbolt sprays 4 MOA, I am going to stock 10,000 of them while the price is that good...
