.303-22 Falcon Cartridge Drawing

Q: I have just purchased a .303-22 Falcon. Keith Bridgeman at Sprinter arms made me a new barrel, but I have not been able to find any loading data. Can you advise me on loads using AR2208, AR2206H with Hornady 40, 50 and 55gn V-Max projectiles? Trim-To and maximum cartridge length? Barry Chambers

A: Why anyone would want to be bothered with a .303-22 Falcon in this day and age has me baffled. I published data for that old wildcat in my first reloading manual in 1980 and since then have left it out. You didn't say what action your rifle is built on - Lee Enfield or M-17 or P-14 Enfield?

My old data was for powders that are no longer available. I have not worked with this wildcat since the 1980s, so cannot offer firm data for current ADI powders. You could start with 30gn of AR2208 behind the 50gn bullet with the likely maximum being 34 grains. I can suggest some starting loads for W-748 and W-760 which I listed back in 1980. It is up to you to work up your own data from this.

With the 55gn bullet start with 34gn of W-748 or 36gn of W-760. Maximum case length is 56.45mm and trim-to length is 56.20mm. There are a lot of .303-25's still in use, but the .303-22, .303-243 and .303-270 have all been long forgotten. Basically, in a Lee Enfield rifle you'll get about .223 Remington velocities.
