Now, the clamp sits evenly around the reservoir without touching and I don't have any shift.

I did originally try with no clamp, but found that as I wanted to keep the original muzzle brake, the barrel would 'bounce' giving me odd random fliers.
Once the clamp went back on with the just the O ring gripping the barrel, the fliers stopped, so result.
mine was bolted both sides and i still experienced random zero shift. im no expert in this matter but i believe that if the POI is different between your standard FTP and your floated FTP (mine shot significantly higher when released to float) then something is affecting the barrel and that will cause trouble. As for barrel bounce or harmonics when you have bare barrel and original muzzle brake im not finding that at the moment.
When I was 5 I wanted to be like George Best
At 10 I wanted to be Nigel Mansell
At 40 I wanted to be like Tiger Woods
At 50 I want to be like Gilly
