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

Hello,

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 was sold out. I had several pounds of IMR 4895 which is a tad slower burning. Since I could not find any loading data for this powder, 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. And again 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
