The more accurate the gun, the more picky it will be. Right?
With an extremely successful groundhog hunt (650mi from home), my son killed em until running out of ammo (223 of my make).
He shoots 1/4moa to 500yds with his Cooper.
Given the rarity in having his hunting company, we stopped right there and bought out factory ammo from several stores.
With testing over 50 boxes of various ammo, we hit on one that actually shot as well as mine. I was stunned.
So we wrote down the lot# and made it a quest to find all we could for 50miles in all directions. Took a couple days, then a day of testing. This was fine. As much fun as hunting really.
But even in same lot, only 2 of every 10 boxes shot well. Enough to get through the hunt, -not good enough to replace my efforts for ammo.
When we got back from the trip, still stunned, I dissected the good shooting factory ammo. It was cheap Remington ammo.
Turned out that the powder was the same, same exact charge, same primer, similar bullet, same exact CBTO.
The only difference is my Lapua brass, and my bullets are custom FB BR.
If I could have bought 100 boxes of that ammo, at 10 for 10 shooting well, I would, and would never reload for that barrel again.
This, even at today's prices.
The ammo that didn't shoot as well as mine? None approaching 1/2moa,, most 1moa or worse.
Can't kill many groundhogs (in fields) with that.
