Hello All,
Yesterday I went to the range. My results are below. I loaded conservative between "normal" and "near maximum" from data was published in Rifle Magazine; Issue #144 - November, 1992.
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 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 from that source. Results in other rifles may vary, so reduce your starting loads and work your way up as required.
Wt. - Bullet - Powder Mfg - Powder - Charge - Velocity 401g - Woodleigh softpoint - Hodgdon - H-4895 - 83.0g - 2,401 fps
401g - Woodleigh solid - Hodgdon - H-4895 - 83.0g - 2,410 fps

Well, I went back to the range today. The reason being that I ran out of Hodgdon 4895 powder that I tested yesterday. I searched all the shops within the State and the also the internet. Every place was sold out - even the Hodgdon web site. I had several pounds of IMR 4895 which is a tad slower burning. I could not find any loading data for this powder, so I thought I'd establish some.
Once again 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)
With this slower burning powder recoil energy was reduced to a pleasant 60 ft/lbs. (one ft/lb less)
This field test again proves velocities approaching 2400 fps are obtainable with the 11.2x72 Schuler cartridge in this rifle. Remember, results in other rifles may vary, so reduce your starting loads and work your way up as required.
Wt. - Bullet - Powder Mfg - Powder - Charge - Velocity 401g - Woodleigh softpoint - IMR - IMR-4895 - 83.0g - 2,373 fps
