Was that old ammo? How was it stored. I have fired a lot of win. I remember when I could buy a box of 50 for $1.50.
Brand new. I've posted this saga several times now.
Years ago, I was on the way to the farm and realized I had brought the wrong range bag. I didn't have the right ammo. Stopped at Wal-Mart and bought a box of the cheapest bulk they had, Winchester 333. When I got to the farm and opened the box half the bullets had fallen out of the cases, and most of the rest wiggled.
I pulled out a handful that looked okay.
POOOOW, piff, fizzle. Some were too hot, most were too weak.
When I got home I called Winchester. You can hear those details in one of the other times I've posted this. Long story short, they sent me a coupon for a replacement box of 333.
Went to Academy and picked up a totally different lot number. I should have opened the box in the store, but I didn't.
Got them home. Same story.
Called Winchester, got called a liar. Sent photos. Customer service manager calls me to apologize. I got a coupon in the mail good for one box of ANYTHING from Winchester and used it to buy a box of .45 Colt Cowboy.
The stuff functioned fine, but was the filthiest non-black powder ammo I've ever fired in .45. The stuff varied wildly in my chrony, too.
I swore off Winchester ammo for years until a similar situation popped up, and the only 12 ga. that town's Wal-Mart had was Winchester Super X. The third round I shot blew my intercepter latch, spring, and retainer out of the gun, and bruised my shoulder to the bone. This was dove loads.
Since having the store I have only bought Winchester when nothing else was available. I have had customer complaints about three brands of ammo in 13 years. One was Winchester 223.
