I am in the process of building a long range gun and have been wrestling with whether to go 7mm Rem Mag or 7mm-300WM.How much faster is the barrel going to burn out with the 7mm-300WM? Is it worth the difference in performance? Do you use the reloading data for 300 Win Mag or where do you get load data for this? New to reloading so I am not sure.

I think it all comes down to what you are using it for. I was looking to build a 300wm but the 7mm-300 meets the needs (extreme long range) better.

If less than a mile 7mm rem mag or 300wm with the right bullet will get you there. The 7-300wm is for xlr targets 2000m plus
I have pretty much talked myself into the 7mm-300wm. Now what do you do for reloading data. The manufactures of the bullets won't give data on wildcat rounds.
