i have been shooting 10mm in a ruger blackhawk convertible 10mm/38wcf for quite a while.
With that long tube on the blackhawk it gets velocities right smart up there.
i would have to check my notes but i am semi remember clocking either 1800 xtp's or 200 grainers in the 1400fps range.
pleasant to shoot too.
That is similar to what I have been seeing. I was looking for the most accurate load from the 10mm revolver with a 200 grain bullet and it settled in with a SD of about 9 fps and grouping just over 2" at 50 yards. The velocity was 1421 fps.No signs of any pressure and very easy case ejection.
