Thor slugs - locally pressed / precision swaged. They work wonderfully and do shoot very accurate. These should perform modestly in P35 / P15 rifles w/ their plenums locally upgraded - you'd be looking at a ball park figure of 800 FPS then, plenty for monkeys.

These slugs do perform exceptional and the accuracy with them certainly is there.

Expect a spread of weight between 22.6, 23.4 grain
