[QUOTE="chav0_12, post: 2357671, member: 29765"] That was something Steve had told me one day. He was saying Litz (or whoever at AB did the testing) for some reason listed his BCs extremely low. I know there was a while back where there was something wrong with some of the bullets that Hammer had produced causing them to exhibit lower BCs, it’s my understanding that has been addressed. The guys at Hammer aren’t just making stuff up when they post a BC, they’re testing with a LabRadar and verifying at distance. Saying all of this to say, the BCs listed on the website are likely more reliable than whatever AB has listed. I was using StrelokPro a couple weeks ago, not with Hammers but with a Nosler ABLR. I had a velocity already established using a shoot through chrono (so I’m not sure how accurate it was), but the program had me dial something like 10.2 MOA at 576. I shot and was pretty high, I shot again because I though maybe I threw it but the next one had the same impact point, so I adjusted the scope to POI and it was at 8 MOA. This rifle is still pretty new, so maybe it’s speeding up, I don’t know for sure. I adjusted my FPS in StrelokPro and it ended up being at 3270 compared to my measured velocity of 2950, which is a lot closer to what I expected the load to shoot. So maybe my measured FPS was wrong, maybe the BC was wrong, I’m not sure, I have to do further testing but I’m not too worried about it until I get something else loaded up for it. [/QUOTE]
