Since we are talking about LR bullets.....A while ago I posted that I could not get the Barnes 168 LR to stabilize in my 7MAG.

Was questioned as to the twist was really not 1x9, gunsmith switched barrels, didn't know what I was doing, etc. I called Barnes and they emphatically stated the bullet was designed for 1X9 twist.
Gave up and went to the 175 gr AB.

Thought I would give the Barnes another try...Guess what the box now says 1X8 twist or faster.....

Makes sense as they are quite a bit longer than the 175 ABLR
