I think you should reload for your 7mm-WSM. The only reason I would tell you not to reload would be if you are strapped for cash or time? Finding a "pet load" can burn up time & money. I have only found pet loads for my 223 & 22-250 on the first day. Most rifles take me several days if not weeks of range/reloading bench time to find what I like. I get picky about my groups. I figure if I am going to take the time to reload, I want to be 100% happy with the end result.
