Re: Do ladder test results tend to xfer to different bullets of same weight?
I have always had to do ladder tests for the same weight of bullet of a different brand or even style. One example is the 200 SMK versus the 200 SGK. Charge for charge, the velocity was the same. Accuracy was a different story. I have no idea why as the look identical except one has a hollw point and the other has a soft lead nose.
On the flip side, when I was switching from the 225 ACCUBOND to the 225 SST. Same charge weight, same accuracy however, the SST's are about 52 FPS slower than the ACCUBONDS. Because the accuracy is the same (very good at .4 MOA), I didnt bother trying to match the velocities by changing charge weights.
Different ogives (land contact), bearing surface, metal alloys, jacket thicknesses, specifec gravities, stability factors etc.......are most likely the cause of these changes.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
