Here are my results with the 240gn XTP using IMR4198. The first 4 are 42gn. The next 16 are 42.3-46.8gn in 0.3gn increments.
Top target was my 4 shot group to make sure I was sighted in. Then the bottom row of targets are the 16 shots. One sheet at a time. Left to right.
The last 4 shots showed a tiny bit of primer cratering. But no issues extracting. And velocity was just a tad higher than listed using a 240gn Sierra jacketed bullet. 42gn-2112fps(shots 1-4), 45.6gn-2276fps(shot 16).
