These are my opinions take them for what they are worth.
The ONLY reloads I've ever trusted were Black Hills, they have established an excellent track record, so much so, you pay a premium for their consistance and accuracy.
I never bought the Centurion that was/is available not that long ago, but enough Arfcommers reported it was decent stuff.
Beyond that, I will always avoid someone else's reloads like the plague. That doesn't mean it's crap...it just means I'm not willing to roll the dice.
You are taking a chance on an unknown.... it's your rifle, it's your body and it's your money. You are the only one who can make the decison. You've got plenty to loose, and only a few cents to gain.
Personally, I'd spend a few cents more and buy IMI. I'd even buy bulk LC over unknown reloads. You are only talking a few cents per round difference.
Better safe than sorry
