Re: I Bought an unknown-hope its a 404 Jeffery/ its 11.2x72

Hello All, and NitroX,

Well, I'm back from the range today. My results are below, highlighted in RED. I loaded conservative between "normal" and "near maximum" as shown in the loading data that I had posted earlier. That data was from Rifle Magazine; Issue #144 - November, 1992 - The last data shown below is from Pierre van der Walt's book "African Dangerous Game Cartridges". It also shows a load with H-4895 powder for the 11.2x72 Schuler.

I loaded using new Bertram Brass with Winchester Large Rifle Magnum Primers and an overall loaded length of 3.290 inches. Powder was slightly compressed when seating the bullets. All fired brass showed NO signs of excessive pressure with easy extraction. Fired primers had normal rounded edges and were NOT flattened. (velocities were measured using a Garman Xero C1 Doopler Radar Chronograph - muzzle velocity accurate to with 0.10 fps)

Recoil energy with this 9 lb 15 oz rifle was a pleasant 61 ft/lbs.

Its important to note: this field test data is NOT a "theoretical contribution", it is "something practical" that proves velocities at or above 2400 fps are easily obtainable with the 11.2x72 Schuler cartridge - at least with this rifle. Based on my test, I would not hesitate to accept all the other published loading data as "doable" in my rifle. (maybe similar powders and components are not available outside the U.S.)
