Yes!  The data in the Hard Air database is just one gun at one velocity with one barrel at one altitude and one temperature. 

.049 sounds perfectly fine. I get .050 to .053 with that pellet in my .22 EDgun R3 Long at 925 FPS.  Just FYI, this is very equivalent to the BC I get in the .25 Cricket shooting JSB Heavy Mk1 at 915 FPS. And, both are better than the BC I get from the .30 JSB Exact 44.75 grain pellets in my Bobcat with ST barrel.
