HEYM "heerenbüchse"
      #225958 - 25/02/13 10:37 PM

Local gunshop has for sale an old Heym single shot rifle. This action type is called in German language as "heerenbüchse". Rifle seems to be in good condition but it´s caliber is little difficult as it is .25-20 Single shot. IMO even those brass are difficult to find. Price is quite high 1350€.

According to Dunlap the .25-20 SS uses an 8" twist, which, I would think, would stabilize any .25 caliber bullet known to man. Such a rifle could easily be converted to .25-30 Winchester (6.5X52R), which is capable of sending a 7.6 gram projectile on its way at 650 meters per second (117 grains at 2112 feet per second). Assuming the barrel steel is of such a nature that it can stand up under increased pressures and velocity, it could be a useful little weapon.

A more potent solution would be to rechamber to .250-3000(R) or .257 Roberts(R), using 6.5X57R brass to form the cases. I have had for over 50 years a Winchester High Wall in .250 Savage (R), which has worked without a flaw for me.

Then there is the possibility of the .25 Ackley Improved Krag, which brings with the capability of performance approaching that of the .25-'06. I have had a Sharps-Borschardt rifle in that caliber almost as long as the .250-3000R.

Probably the best solution would be a rebore and rechamber the barrel to 6.5X57R or 7X57R. Either one would turn this vintage single shot into a useful hunting rifle.

The Heeren action was the invention of count Arturo Massa y Heeren, a Spanish-German gentleman, in 1880. He gave the patent to Nagel & Menz in Baden-Baden. So the early Heeren actions are all marked by Nagel & menz. But N&M never made "their" rifles. As usual they had them made by the Suhl guntrade, first by Stephan Heym jr., then by the son Max Heym. Both are not related to the still existing F.W.Heym company, now in Gleichamberg. After the patent expired the Heyms, father and son, made the rifles under their own name. Max Heym had the word "Heeren" protected as a trademark. Max Heym continued up to 1938, when he sold out to Ernst Kerner & Co. because of old age. Kerner continued to make Heeren actions and rifles until 1945.
IMHO rechambering this rifle to .25-35 Winchester is a perfectly good idea.

The Heym Heeren are made in very fine quality.
If this rifle would be for sale in germany i would not think an minute to buy it.
