I have the screwiest problem with the ammo named above, coming out of my Endeavor 300 Mk 4. I have not scoped the bore yet, so this could still resolve down to something stuck in the rifling, or some rifling screwed up.
At the range recently, I was sighting in at 100 yards. It had become "obvious" that I had not sighted in properly before. (I put it in quotes because clearly what was obvious to me was not apparently the problem at atll.) Fine. It happens. At 100 yards, I saw an occasional identifiable strike, but always keyholes, not pencil tip holes. Other than that, I saw nothing. I simply could not see that I was hitting the 6' x 4' target. At 100 yards! With a 5-25 Viper Vortex FFP scope! Makes no sense, right?
After 40 rounds I gave up and waited for the call to go cold. As I was bringing the targets back, I saw the few holes I mentioned, keyholes, and hundreds of tiny pinprick holes all over the targets. The obvious joke was made immediately when I got back to the firing line about no one realizing that 6mm ARC was a shotgun round. It did truly look like shotgun hits, but tiny little holes all over the place, just about literally pin pricks.
The next step was obvious: try the 25 yard line. At 25, perfect. POI married to POA in 3 shots, plus 2 for confirmation.
The next next step: try the 50 yard line. Again. Perfect. Set with confidence at 5 rounds. Then I shot a few more just for the pleasure of seeing the damned things hit where they were supposed to go.
So, somewhere between 50 yards and 100 yards, something weird happens that certainly looks like bullets disintegrating and spraying the targets.
Have any of you heard anything from anyone remotely similar to this report?
My borescope will arrive Friday and I will take a slow and careful tour of that barrel. With just a flashlight at one end and looking through it, I don't see anything obvious, but, the scope will get the final say on that.
Thank you for anything, anything that you think of to say on this topic, period.
I've reached out to Hornady and supplied the Lot # for the boxes involved. If they add anything to the discussion, I will bring it here.
