Did a Ladder test with my 30-378 180gr Barnes TSX and 180gr Hornady IB bullets.
What do you Ladder test experts think. Starting load was 107gr Retumbo, load increment 1 grain, high on TSX was 113gr and 112 on IB.
All shots at 100 yards 1st shot on each from clean cold oiled barrel so I would throw out shot 1.
Shot 5 is between 3 and 4 and shot 2 is below shot 3.
I am thinking I will just go with 111gr Retumbo with both bullets which would be shot 5.
The TSX bullets were very impressive. A .8" group for shots 2 through 6.
Looks like this rifle loves TSX bullets
