I sent my twinmaster to Brocock in December for a trigger repair and service.When I got it back I plunged into the UBC competitions and didn't shoot much at more than 10m.
I was shooting at 20m last night and quite frankly the groupings were low and very poor. I swapped guns with a much better shot than I and my grouping were normal for me and his got much worse. I chronoed the pistol today (without killing my Combro) and over 8 shots got a difference in MV of more than 30fps betwen the highest and lowest reading. ME ranged from 1.75 to 1.05 ftlb.
Back to Dr Brocock on monday.
Anyone have any info on how consistent the Rohm should be?

Looks like I'll be shooting the next round of the comp with a borrowed Rohm. (excuse 74c)
sent mine to mr hassel ,,4ftbs and very consistant your aint well
Spoke to Brocock this am, convinced them that it wasn't working properly after the last repait and they will put it right FOC... will try this first. The gunsmith there said Rohms were hard to adjust upwards above about 380 fps
Less than 24hrs after I waved my Rohm goodbye at the post office, Phil (?) from Brocock was on the phone. He'd found a flaw in the casting inside the reducer valve which had perforated causing air to leak. Yippee! Should get pistol back by thursday.
How's that for service?
Brilliant news
Three cheers for Phil @ Brocock

Phil said he'd chronoed the gun and it was doing an average of 420fps, which seems fair enough.
Just out of interest - Who's Mr Hassell and what miracles does the man perform....???
Phil Hassell, does tuning to the Rohm Twinmaster PCP pistols, including reg tweaks and more hammer spring preload to boost the power.
Contact details www.pmcb.co.uk.
I don't know if he still does them though and I hear he can be difficult to contact sometimes.

just chrono'd my twinmaster top at a consistant average of 456 ft/sec with 7.0 grain RWS CO2 targets, thats 3.23 ft/lbs.
