Home Forums Hunting & Shooting Ask The Gunwriters Hercules Unique in .222 Rem?

I have never seen any published data for Unique and jacketed bullets.
Lyman shows 6.0gr start load and 8.0gr max load for 55gr cast bullets velocity in the 1800 to 2200 range. They also show 36000 cup with the max load so these are not wimpy pressure loads. I don't believe those loads would be safe with jacketed bullets or at least not worth taking a chance.
