Was at the range yesterday and one of the guys out there showed me a target he just shot where the bullet tumbled, creating an oblong almost side view looking hole in the target, low and left of where he ws aiming by a good 3 -4 inches.
The rest of his shots were all inside of half an inch. He is a very good shot.
He was shooting a 6.5 CM with 147 ELDMs over H4350. As we were talking about things he mentioned that it usually happens somewhere between shots 20 -30 somewhere around 25 or so.
His velocities were pretty good right around 2700 or a touch below.
The barrel had been cleaned about 50 rounds ago.
He has even gone so far to length check and weigh the bullets. All were within a grain or grain and a half or so. The tips weren't deformed lengths were all very close.
Any thoughts on what could be causing this?
The only think I can come up with that he hasn't checked in bullet diameter and I am just guessing could this happen from the bullets be undersized?
