I tried the xtreme bullets because at one time that was all i could find in stock for a while.
I tried them in 380 auto flat nose, now I almost exclusively use em in .380, 9mm., their 230gn. rn for the .45,
and their 150gn. for the 30-30, and 300 blackout. (mixed results with the blackout, but for plinking, the occasional FTF was and is expected.)
for the price, I find em hard to beat.
I have had very good luck with everything Ive tried them in, and shoot A lot of their bullets now, I recommend them highly.
Just don't try to push them to ludicrous speeds and they work excellent, nice grouping, and repeatable results and accuracy.
their finish, seems to me anyway, smoother, and more "even" that the Berry's.. hard to explain, but when you compare them side by side, the finish on the Berry's looks kinda wavy to me, where the xtreme seems smoother, or more "finished".
