I am thinking of trying some 140g CT BT's in my 7mag. I have been shooting regular 140g BT's. Will I notice any difference in the way that they shoot? and is there any real advantage to the lubalox coating?
No real advantage to using the Lubalox coating.
I have used the regular 7mm 140 gr BT in my 280 Rem and have had perfect results on WT Deer and Caribou. Accuracy is sub MOA.
