Does anybody know where I can get factory loaded Barnes TSX bullets in .223? I was thinking of going with the 62 gr. or should I just load my own because I don't plan shooting that many of them. And what twist rate would be best with it sense it is an all copper bullet so it is probably longer than an all bullet of the same weight, because twist rate based on length and not weight, am I right on this? |
Corbon loads the 53 gr in DPX. http://www.safariarms.com/ will do custom loads and they mention the TSX. Chad |
| I think Black Hills made some factory Barnes X loads. Just for your info...i load the 45 grain in my .220 swift at around 4000 fps, and love it. I went to this bullet after having one too many V-Maxs blow up on a coyotes ribs. I also hunt with 7mm X Bullets, and hope to try the MRX's soon (They have the delrin tip and the tungsten base for long range). I have been every impressed by their performance, even on elk here in this state. If I were you, I would have a handloader load up some of them for you as a reduction in overall costs, and to try them before you commit to the copper club. |

As the OP correctly observes, all-copper bullets are significantly longer than copper jacket bullets of the same weight. The rifling rate nevessary for stabilization is dependent on bullet length, not weight. Weight is used as a common indicator of length, as they are directly proportional and twist rate rules of thumb are based on the assumption that the weight to length ratio is that of a jacketed lead core bullet. Well, that rule of thumb goes out the window with monolithic bullets, particularly those made of metals lighter than lead. I would strongly suspect that nothing short of a 1/8 will stabilize a 62 grain, all copper bullet, which is even longer than a 62 grain SS 109 lead/steel core bullet. |
