Re: 243 wssm
I wouldn't be too concerned with it burning out your throat anymore than a regular .243 win. They have pretty close to the same case capacity and neck length. It just sounds like a barrel burner with that "mag" naming, but it really isn't a true magnum. Now the .223 WSSM on the other hand, watch out! There is a reason they come from the factory with a chrome lined barrel and it ain't for the looks man!
If it's not far, it's boring.
