I don't think you can go wrong with either. I have used the tripleshock but not the MRX. It looks almost the same but is stated to have better downrange performance. That can't be bad. Availability may be an issue with the MRX.
ok thanks for info. i personally use the 180 grain win supreme accubonds in my 300 wsm. its a browning a bolt and seems to like them very well and its one of the best bullets ballistically that i can find (if not the best)
I still use the same bullets as ten years ago man I figure if they do the job and you havent had any probs why switch I try out diff ones here and there but most dont compare to my federallies but Im sure if winchester makes em they must be good. 2 things that never let me down in my life my dog and my winchester.
First make sure your gun is safe, remove the bolt and clean your barrel from the chamber to the end of muzzle. Clean the barrel using butchers bore shine until a patch comes out white. Run a total of 5 separate patches soaked with denatured alcohol through the bore and let dry for 30 minutes. Insert a cleaning rod with a jag and a dry patch into the neck of the chamber. Make sure it will stay there through the next process. Now using another cleaning rod, install a patch that has been coated...
