[QUOTE="JungleShooter, post: 2209915, member: 110729"] It seems the Velociradar [I]basic unit[/I] only measures velocity [I]at close range[/I]. And that "feature" seems to relegate its use to measure muzzle velocity.... 😟 But I'd like to start [B]measuring velocity decay downrange[/B], in order to produce more reliable [B]BC numbers[/B] than the ammo manufacturers are sharing.... Because an airgun [I]hunting pellet[/I] really suffers massive drag due to its[B] aerody-or-fly-ashtray shape [/B](just look at the photo!). 😱 Now the expansion is amazing, but it needs to hit the quarry at a pretty good velocity for the HP expansion plot to play out. [ATTACH type="full" alt="H&N. Crow Magnum. #01. Side. [Crop. 01.png"]277376[/ATTACH] The succession of futility for hollow point pellets goes like this: Low BC ➔ Rapids velocity decay ➔ Low impact velocity ➔ No expansion of the hollow point ➔ [B]What's the point of a hollow point if it does not expand?!? [/B] So, what I'd need for my application would be the Velocidarar [I]Alpha[/I] model — and that comes in at LabRadar prices (at least going by the tease pages at the sellers). Still something to watch for. I need to check how much play money the piggy bank holds... — I'd love to buy a used LabRadar if I can get it at a good price.... 😊 [/QUOTE]
