Waiting to try them out, does not look promising
As other comments have noted, these are not vacuum sealed as advertised. Inspected the first round I picked up and the copper open-tip is not cast perfectly, with a burr on the open-tip, which will ultimately lead to an unbalanced spinning projectile. I'll see if I can update after a session at the range (if I can edit my comment), but I'm not 100% sold these are match quality. Quick shipping, okay price for the quality of rounds delivered.
