went to the range today with a friend who was wanting to sight in a new CORE15 rifle with a burris AR-332 sight on it. he is a Marine and knows his way around the M4 platform. it took 3 shots to get it close at 50 yds. over the next 10 shots it printed a 6" group. mostly it was around the POA but with odd fliers in all directions. I shot it and had the same issue. two shots where I was aiming, then two shots 4" right, then a shot 3" low. this was off a bipod with a rearbag support in an AR15. this type of accuracy was just not acceptable.
so we checked the gun, all seemed normal
then we checked the ammo, it was independence 5.56 nato 55g fmj (https://www.midwayusa.com/product/3...ato-55-grain-m193-full-metal-jacket-boat-tail)
the seating depth was a little all over the place. one round the cannelure was not visible, the next was a middle cannelure seating depth with a visible crimp, a third was not seated up to the cannelure.
we decided to figure out if it was the ammo or the gun, so he shot some of my factory ammo, i think it was some Winchester Law Enforcement 55g soft point that I had laying around. this printed about 1" out of 5 shots at 50 yds.
my reloads performed similarly in his gun and I KNOW with 100% confidence what sort of QC is in place at MY ammo factory.
all in all we had a good day at the range, did some shooting, sighted in a new gun, and reaffirmed why I am glad I reload.
