Thread: 6mm ARC

Yeah stay within the limits of the bullet at the speed it's going. Which for a 108 out of a 6mm ARC might still be about 500m.

I see what you’re saying. Wiki tells me 108gr MV from 24” is 2750. Take off 8”, it will be 2550. G7 will be 0.261
Strelok says velocity at 500m will be 1730 f/s and will that bullet expand much ?
KE is 715 ft.lb
A (big) wallaby chest is about 5cm ie 0.1 mRad at 500m. Full value windage for 5m/s cross is 1.4, so only 0.3 mRad for 1m/s …
So, work within the limitations of the cartridge…
