Rather careless email in respects the group sizing and more importantly referring to the rear sight needing to be HIGHER to bring the POI down. Hopefully both are typos, the latter statement would have me questioning the credentials of the gunsmith. Shooting off hand to check regulation is also surprising in that results are very dependent on the ability of the shooter. Like John I would be expecting the forehand to be supported. How many of us would check the grouping ability of any rifle or gun by shooting unsupported offhand at 100m????

Surprising also is the rather nonchalant response to the gun shooting high. I would have thought some correspondence from the gunsmith to ascertain if you wanted some work done to the sights to remedy this or alternatively look at the cartridge loading to achieve a lower POI. Obviously changing the load could affect the regulation. Was the gun shooting high before it went to the gunsmith? If so then tweaking the load to lower the POI should have been done before sending for regulation?

I wouldn't be overly enthused about the work although I guess with short range cast bullet use it may suffice.
