Been out shooting my MP 10 in 6.5 creedmoor. Today at 200 yards enjoyed a three shot group 3/4" across. Sub moa with an over the counter semiautomatic action. Not bad!
Question: I have a Colt "Sporter" (AR-15/.223). It too shoots impressive groups (5 rounds at 100 Yards into 3/8")------when fired S L O W L Y---from a cool barrel.
Fired rapidly (enough to warm up the barrel some), those impressive groups (Also fired S L O W L Y---but from a warm barrel) become a thing of the past.
I'm assuming the same exists with these rifles----yes?
