Mike Davisslimjim/Xman has done heaps of testing of these and all sorts of .277 /6.8mm projectiles
some of the projectiles have a bigger cavity than others the TSX IN 110 GRN comes to mind. they now have range right down to 80 grn as the 6.8spc11 has really opened doors...in a mini 14= ymmmmm
he has tried taking plastic tip out/adding it in/deepening blah blah blah
conclusion what works works really well. he got me convinced re 110grn then goes and shoots elk at couple hundy with a 130grn GMX with great results.
if anyone wants to see this info I an go and bump it forward,not sure if I posted link in the 7mm thread earlier.
