I got the .30 caliber 700mm M3 on its way right now. should be a couple more days maybe Monday. I'm sure with the quick tuning and the superior liner plus the carbon sleeves, I think switching back and forth for hybrids or slugs and pellets will be fairly easy. Luckily for me, I have a lower caliber Impact MkII at home now so I can just easily switch the barrel and probe over. (Which in all honesty is never bad to get if you are stuck between what caliber should I get haha)
