I have not tried them in my 300wsm but have used them in my 270wsm. The scirrocco's anyway not Remingtons factory loading with them. I have taken both deer and antelope with them with great success.

I will state again I have used bt's and never had a problem with them and have seen countless animals taken with them.

I pretty much switched from them when some of the newer polymer tipped boattail designed thicker jacketed bonded bullets came out. I was getting the same accuracy out of what I think is a better constructed bullet. And this is truly just my opinion.
