Re: Shooting max load bad for the rifle?
[ QUOTE ]
I was wondering, is shooting MAX loads for the bullet weight worse for the rifle as compared to shooting MIN loads for the bullet weight?

YES - In that "max" loads produce more heat and pressure which invariably shortens throat life. It also greatly shortens cartridge case life as compared to "min" listed loads. Loads above "max" are detrimental to the firearm itself.
Since very few shooters have any reliable way of determining when they are actually using a "max" load, you can bet that many shooters are unwittingly using loads that are quite a bit beyond the maximum SAAMI pressure limits eastablished for their particular cartridge.
How many times have you read (on the net) about someone who is getting velocities well above what the loading manuals indicate. In all likelyhood, they are exceeding established maximum pressure limits. You know the saying there's no free lunch.
I'd suggest using a good chronograph along with your reloading manual when working up loads.
