I posted this in ballistics too, but I know more folks are in this area and I'm looking for info...
I shoot a GAP 308 with a Bartlein with 5R rifling. Both 168 and 175 grain SMKBTHP hit at the exact same spot at 100 when zeroing. I picked up a box of 150 grain and I'm curious if you think they will also hit the same spot at 100. I will get to the range to confirm at some point, but I'm sure someone here shoots multiple grains and can tell me.
Where will I see the most gain or loss with a lighter round?
Thanks!
