Olympia slugs from Predator?

Had a credit on Amazon so I ordered a tin, supposed to be here Wednesday, weather for Thursday is sunny and calm so I can head to the range with the chrono for some testing with my Armada, Cayden and Flash, if they don't fit the mags it's going to be a pain, only have a sing shot tray for the Flash

weight was consistent, 2 slugs at random always equaled 50gr, sizing was .2145, .215 and .216 with the majority .215, .216 was running maybe 1 out of 10, they fit the Flash mags with no issues, fed smoothly and chambered easily.

Originally cranked the speed to around 850fps, and backed it down to just under 800 where it settled into a decent group for the gun.

Time for a range day tomorrow
