Hello all, I have a Browning .308 X-Bolt, I am using 150 grain bullets. My question is: Does it matter which brand bullet I use as long as it is 150 grain bullets?? I sighted my .308 in with Winchester 150 grain bullets. Now, if i was to use Hornaday 150 grain SST bullets, will they shoot the same? Or should I use the same brand I sighted my .308 in with?
