My M&P is a 1 in 8 twist barrel, and have only used 55grain rounds.
Now I have seen 62grain and higher, and was curious what is the highest grain I can use with a 1 in 8.
Or better yet what grain should I stay between for the gun to fire properly.
I've heard if you go too low it will not cycle properly and too high you risk damage to the barrel from the hotter round. Havent seen anything in black and white to tell me the difference and limits to use, just info I have got from ppl when I came across different grains of .223/5.56 ammo.
Any info would be a great help....
