Tuning Bantam HR 177 and RD monsters

[pesty3782]

Getting ready to do some groups with this tune...Does anybody else have a good tune for the JSB RDM 13.43? Also does anybody know the twist rate on the barrel? This was shot with a starting pressure of 200 bar.

Thanks

Tony P.

Well since nobody commented...

I only tried the original 13.43gr Monsters in one of my 177s and it shot extremely well a hair better than the 10.34 JSBs. This is from an unregulated Bantam HiLite though.

Both had best accuracy results at max power level on the TP restrictor knob.
