[QUOTE="TRexF16, post: 2354975, member: 108912"] Has anyone (Mr. Litz, perhaps?) tested the BC of this bullet? Sierra's published best case G1 of .560 in a 1:8 twist just looks a little conservative for such an extremely long bullet. And they didn't list a G7, which I would figure is the more accurate BC to use if available. I shot these for the first time today in my 1:8, 24" .270 WSM and it looks promising, but if the BC is really that much worse than the 165 ABLR I don't know how deep into the load work I'll go. 2850+ looks like it's going to be very comfortably achievable, so that's the speed range I'm interested in. Any help? Thanks, Rex [/QUOTE]
