Thor slugs - locally pressed / precision swaged. They work wonderfully and do shoot very accurate. We recommend these specific ones for your SUMATRA 2500 model PCP rifle.

We've had success with these in applications such as the HATSAN BLITZ (indicated)

These do work really well, though again, as is the case w/ H&N slugs - please check and test to see what diameter and weight your rifle prefers.

These are flat based slugs, meaning, at the base, there is no indent, only a circumference lip.

Expect a spread of weight between 32.0 ~ 32.6 gr
