OMG! Ok! Thanks for the comment!Both my R7 and HW30 can shoot the newer JSB 8.44 well but the fit is so loose you risk ejecting the pellet right out of the breech as you lock up. The AA 8.4 fits well. Has to be something with the dies.

If you're talking about the 177 10.5 gr pellets, just be aware those are on the heavy side for that power plant. You'll likely lose a good deal of velocity and energy. Spring life will likely suffer a bit. Typically Hw30s are best suited to lighter 7 to 8 grain pellets. A little over that is OK. A chronograph will show you if they're good for the gun or not. The lower the energy the harder the pellet is on the gun.My HW30 shoots the new Benjamin match grades really well!
