I think I may have a problem. I just can't stop trying new bullets and probably will burn a barrel out before testing is complete. The wise and experienced person would probably focus on tried and true bullets and leave well enough alone. I do know that sometimes a particular rifle/barrel has preferences that shoot well and others that just don't. I shoot more .284 bullets than any other in my rifles. I got lucky in my .308's and found a bullet that met expectations early in load development. So how many do you test in a new rifle.
Here is the current line up for my 280AI.
