Ok. I have quickload. My question is. If I switch from a 175 smk to a 155 berger If I match the fps up with my load should I expect the same performance? Will it group the same as my 175 smk load? I have been lucky so far doing this with powders matching the loads for fps. So I was wanting to know if I could expect the same swapping out bullets. Just for an example I use R-15 and 748 with my 175 smks. I cant remember the exact numbers. Say the r-15 was saying 2,800 fps so I matched the 748 load to 2,800 fps. So far they seem to impact and group the same. But I have only done about 20 rounds each test. Seemed to work. But what do you guys think?
