I bought these because they were the cheapest in the shelf. 12ga 300gr 2000 fops muzzle velocity. They made a weird whistling noise when I sighted in my gun last Friday, but that might have been the echo from the nearby hill or something. They definitely fired differently than the remmington golds I used to shoot. SSTs also seemed to shoot higher and to the right. Jury for me is still out but at $12 a box and the fact that I did get my doe yesterday makes me think they'll be ok
Love em. Never heard the whistle. Killed a couple deer with them. 2 inches high at 100 makes you 6 inches low at 200. I did have a gun once that could not get groups with them. Otherwise my current slug gun loves them.
I tried hornady SST's last year and They didn't leave much for a blood trail so i switched to remington copper solids. My brother shot a doe with the SST's and the bullet entered behind the front shoulder and lodged in the hip. That bullet never opened at all and the stupid red plastic tip was even still in it. Junk. but they do shoot good.
Life is like a coin, you can spend it anywhere you like, but you can only spend it once.
