Wildcat Sniper 30 FX slugs

I would like to try my sniper with slugs but not sure the speed would be enough.

I am running 125 b on regulator and the fastest consistent velocities I get are around 904 using JSB 44.7 grs

Best accuracy with pellets is 870 for me.

I was going to try the FX hybrids but didn't want to go to extremes on press for them.

Any one have any experience with the 30cal sniper and slugs?

Thankyou
