I have used them in a .25-06 with great results on deer.
I have used them in a .243 Win with less than pleasing results as it appeared to not expand as much as I like on deer.
I tried to load them for my .338 WM but couldn?t get the accuracy I wanted. So, I have a box and a half of the bullets I am trying to figure out what to do with.

I am not a big fan of crimp rings on rifle bullets. So, I usually stay away from the SST.

I won?t use them anymore in the .25-06 because I have a more accurate bullet now with equal terminal performance. And I won?t use them in the .243 Win because they were too tough for me.
