first of all you need to determine what the load you work up, is going to used for. so you need to choose a bullet weight that will do the intended job for that load. is there a need to run that fast of a velocity to begin with? velocity does not always equal accuracy.
anytime you run really hot loads that have small bullets, you run the risk of throat erosion. it's part of the price you pay for that joy of shooting very fast and small bullets with a large case. if throat erosion is a big concern, then stepping down in velocity is what is needed.
case in point. my father has Winchester M70 in 243 he bought in the late 1960's that he has reloaded his own ammo for well over forty years and has many thousands of rounds and hasn't lost any accuracy yet. but he never looked for velocity, but accuracy over the years. most of his loads he made for the rifle were in the 80-105 gr. weight range.
now if you want to run 55-60 gr. weight bullets at around 3800-4000 fps range, then there is the possibility that increased throat erosion is going to occur. how many rounds before accuracy starts to fall off is a guess at best. but how fast it takes within that range is a guess too. if it takes say, 3000 rounds to wear out the throat that accuracy is degraded, and you shoot 150 rounds a year, that's about 20 years until you see the accuracy degrade. now if you shoot about 500 rounds in a year, that is now down to six years and if you shoot 1000 rounds a year, you are now down to three years before looking at a barrel change.
