It was warm enough to go shooting today temp 55 degrees, Wind 10-15 MPH and more wind than I like but hea it beats not shooting. Relative humidity 81% Pressure 26.96. I only got 3 loads shot for the 308MX. I figured I would try the Hornady 150 gr GMX #30370. this bullet would only be able to be loaded with one in the chamber and one in the mag, but I figured it would be fun to work up anyway. I shot Leverevolution powder, the targets were shot at 100 yards with the wind at my back with a right to left quartering angle across the range. 42.0 gr = 1.5 inch, 42.5 gr = .25 inch..yes 1/4 inch, and 43.0 gr 1.75 inch. Hornady brasss and Win LR primer

The 338 MX didn't go so well. I tried the Barnes 185 gr TSX HP bullet with Hornady Brass, CCI 200 Primer and Leverevolution powder 45.5 gr = 2.75 inch, 46.0 gr = 2.25 inch, 46.5 gr = 2.75 inch, 47.0 gr = 4.0 inch, and 47.5 gr = 4.0 inch,
Also shot the 200 FTX bullet with same brass and primers
45.5 gr = 3.0 inch, 46.0 gr = 3.5 inch, 46.5 gr = 3.25 inch, 47.0 gr = 3.5 inch, 47.1 gr =3.0 inch
Not real impressed with the 338 results.
I did not check any velocities it was too windy to try and set up the chrono and I usually don't bother to check velocities until I have an accurate load. It takes concentration away from shooting a group to try and have the chrono lined up so I don't put a bullet through it.
Back to the loading bench.
