Brocock/BRK Sniper XR .177 low power setting pellets

So was curious if anyone has any experience with a good pellet for the low power settings on a Brocock Sniper XR? I have had decent luck with 7grain cheap pellets but would
Like something more consistent. I'm trying to hold a close zero to my 10.34's at the highest setting. Any one have any feed back on this or do I keep buying a bunch of random pellets 😜
 
Im shooting Benjamin 10.5 at 878 fps on high and Jsb 8.44 at 801 on low. Haven’t tried the Jsb 7.33 yet.
