Faster twist and stainless... Someday you are going to want to push the bullet wight up and that faster twist will make all the difference in the world...
BTW, the .35W is a "magic" round if they exist at all. I was torn between it and a .338-06. I went with the .338 but would not have been unhappy had I finally decided on the .35W. And, mine is for the same purpose. Heavy animals at reasonable ranges... Almost the same setup except for a 24" Douglas barrel (I have had very good luck with them in hunting rifles).
