Shot my Lott yesterday for the first time.
The loads were
300gn Taipan (light load)70gns AR2207 2400fps avg
300gn Barnes 82gns AR2207 2650 fps ,86gns AR2207 2800 fps
400 Woodleigh 82gns 2206H 2200fps (Fairly mild load)
500gn Woodleigh 82gns 2208 2250 Fps
405gn cast bullets 66gns 2206H 1900 fps. (shocking accuraccy)
None of the loads showed any presure signs at all in my gun. I will be going up to 85-86gns 2206H with the 400 woodleighs and maybe 84gns 2208 with the 500s .
All the jacketed loads were very accurate in my gun.(A lot more accurate than I care to hold it on the bench for many shots.)

cr500,
I'm at 83gr AR2208 behind a 500gr Woodleigh, MAST case, WLR primer and zero pressure signs, with long case life. I have a sneaking suspicion that "full load" will be somewhere in the 86gr range for my CZ550..... but then I could be wrong too . My velocities are in the same range as your with the 500gr Woodleigh and AR2208.
Cheers...

Thanks guys, looks like I'll be in for some more punishing bench sessions.
