My neighbor who passed away a few years ago killed countless elk with his .25 Bob. All he shot were 100 grain Hornady flat base spire points. If your daughter is good with the bob, let her keep shooting it until she gets a little bigger. Flinch
That's a good suggestion right there and it gets rid of all the horsechit talk about sectional density, bc's, OGW comparisons, etc. I wouldn't see any difference between the 257 and 260 either that some of these guys are suggesting.
