Chris;
I am not certain, but since William Ford is a particular Birmingham maker that I have been interested in for years, we may have.

Typical Raschsche square engraving usually has a prominent dot in the middle of each square. Here, I can't make out the dots. Mike

Well then, atypical „Raschsche Karreegravierung” or „Rasch’s squares engraving”. I will find out.

It doesn't make much difference, only that it wasn't likely Rasche that did it. Mike.

Rasch didn't apply adornment, but it was some contractor that has been masked by the sands of time.
But what the atypical „Raschsche Karreegravierung” or „Rasch’s squares engraving” does do is point towards the hand of Wilhelm Schilling circa 1910.
Hochachtungsvoll,

Quick update - had the rifle back out to the range today. Same 200gr bullets and same powder and charge, but this time added kapok fiber as a filler. Velocity increased 120fps to 2085fps and std dev decreased from 121 to 18fps for a 10 shot group. So much more consistent. Results on paper were a little bit confusing. Not awful but not really better than load w/o filler. Need to digest what I was getting. Will post pics later.

Chris;
Do you have one of the "Virtual Ballistics" software programs such as QuickLoad that allows you to enter the loading data and predict the velocities, energy and chamber pressures (and barrel pressures) of the loads you are shooting? If not and you would like to have this data send me a PM (with your email address) and I can run the data and send you a print out of the data and curves. Data required from you will be propellant, projectile diameter and weight, case length, primers, barrel length and bore diameter and so forth. I can send you the print out via your email address. The QuickLoad software that I have is produced in Germany and I just looked at the basis in it for 9.3x72R cartridges and there are two different 9.3x72R cartridges (1) 9.3x72R (.360) which has a case length of 2.835 inches or 72.01mm and (2) 9.3x72R Sauer which has a case length of 2.830 inches or 71.88mm.
Kind Regards; Stephen Howell

Check the crown on the muzzle especially the RH bbl. Perhaps it has some damage or has been repaired from damage,isn't quite square, etc. Also check the rifling at the muzzle in the RH bbl.See if it's been worn on one side.
Set the bbls up on a sturdy rest, with the sights right on a target dot at say 100yds. Thensight thru the bores of each bbl. Just to see if perhaps the RH bbl is way off the mark.
I realize the bore allaignment won't be on the target mark, but it would seem if the RH bbl was set way off somewhere it might be the problem and not the load.
