RE: Hornady 140 gr. BTSP .270
I have boxes of the 140 gr bullets and loads and I can tell you that they retain more down range energy than the 130 gr bullets and are deadly on whitetails.
One of my rifles is sighted in for 140 gr bullets only and it shoots bullseyes all day long at 200 yards.
Speed isn't always the best thing for a deer rifle.
The 130 gr bullets fly faster, but they are not any better than the 140 gr bullets.
