I baught some for my 270 and 30-30. The 270 shoots an inch eassliy and I haven't tried the 30-30 yet. The real test will be on game though and with 2 1/2 boxes in reserve I will find the answer tot hat question this season. I read on another forum about a guy using the 30-30 vestion them on on hogs and axis with devistating DRT results and good exits.
