Never used the 300 gr version but the 240gr XTP accounted for 9 harvests of my own(8 deer and 1 black bear). All were one shot kills at varying distance from 25 yards to 147 yards and complete pass thru's with very little tracking required. In my current ML 100-110 gr of Pryo select produced excellent groups as did 2 x50 grain pellets of either T7 or Pyrodex.

I would say 7 bucks for 20 is a little better than average, seeing they sell for about 10-12 in canada. I bought a number before in bulk(as suggested) they cost me .30/piece vs .55/piece for the pre packaged 20's, as such I still have a number and use them for practice. I currently load 250 gr SST for hunting which cost me about .70/piece.
