35 ft/lb .22 Airwolf trajectory

Postby Nexus180 » 12 Mar 2015, 13:39

Hi all - I use Baracuda 5.51 at 35ft/lb in my .22 Airwolf. At the moment I only use it at night with a Yukon Photon NV scope, which limits my reliable range - I try to get to 30m or less. I zero at 25m and roughly speaking between about 12m-30m it is not worth trying to hold over/under as the POI only shifts by less than 1cm. Then for some reason by 35m the POI has dropped by about 3cm. I have to say I'm surprised by this - although I'm sure someone more knowledgeable than me will be able to explain why?

I shoot my FAC Huntsman set at 30ftlb with 21gn Bisley magnums but I moved to 16&18gn JSB`s in 5.52 and find them great on quarry and alot flatter shooting than the 21gn magnums. I also zero at 40 yards.
