Any of the crew ever have a 30-40 Krag Improved? If so tell us about it. Barlow

I will assume you are referring to the Springfield military rifle. The 30/40 Krag rifle is suspect. There were other rifles chambered for the 30/40 round, the 30/40 chamber is one of the chambers that benefited the most by the Improved design.

I had a Ruger No. 3 carbine in 30-40 Krag and dreamed of rechambering to the 30-40 improved. Then when I used it the first time during deer season in very cold weather carrying the cartridges between my frozen fingers the dream faded. I decided my fingers would be warmer if I carried my 03-A3 30-06 and wear warm gloves, I sold the single shot carbine.

I would not conceder rechambering an original military because it would destroy its value. The No. 3 Ruger carbine was a strong action but not suited for fast action woods shooting in cold weather.

I have a 14" contender chambered in 30-40 Imp. Haven't had a chance to use it much but this might be of interest...

30-40 Ackley Improved - Developed with the object of attaining approximately 308 Win/30-06 level velocities in small actions like the Model 97D rifle and TC Contender. The narrower body diameter and Ackley Improved shape produce minimal bolt thrust. These loads were worked up in our Model 97D falling block rifle using Dry Remington Brass and a Dry Chamber to take advantage of the Ackley shape in reducing bolt thrust. Primers were CCI Large Rifle. Three pressure indicators were watched for: Primer Flattening, Chamber sticking, and Block Dragging. After firing the maximum load (below) the Model 97D action always opened easily (without dragging) and the cartridges ejected freely (without sticking). Primers were not excessively flattened. Different guns (even different Model 97Ds) could behave differently. Always start low and work upwards gradually (.5 grain increments). Watch for pressure signs in primer flattening, chamber sticking, and/or block dragging and STOP INCREASING.

Then buy a 30-06 rifle and pretend to be Sgt York and tell the bench rest shooters here you can shoot the head off a turkey at 500 yards.
