I agree with youstating the TSXis at its best in the magnums, but they also havebenifits in the non magnums. The Barnes bullets have better BC than most any conventional bullets and this will help maintain downrange energy in a cartridge that is marginal for the job like some non magnumscould be in certain situations. The weight retention of the X bullets especially in a non magnum is also very high which will help with penetration in a shoulder shot for example. I have always felt like the extra penetration of the Barnes was like jumping up a cartridge vs the jacketed bullets.Some say the Barnes bullets may not open at low velocities and that may be a good thing. If the bullet lacks velocity and KE I feel it may actually be better to not expand and just penetrate to ensure the vitals are damaged.
