Single Action Data
For the first time we present a separate section for Single Action Data. Many of these loads were developed through an extensive program by the Hodgdon Powder Company Inc. of the USA, to whom we are indebted for their contribution.
Velocities for all cartridges listed are limited by the SAAMI maximum allowable pressures. Minimum loads are established by pressure. Loads with very low pressure may fail to function in very cold weather, resulting in a bullet becoming lodged in the bore (please see the Warnings section of this guide).
The average loss in velocity from the listed pressure barrel data when using a 4 5/8 inch barreled revolver is 175 fps. A 7 1/2 inch revolver will lose about 50 fps.
Carbines will generally develop velocities similar to those listed in the data. Some carbine/cartridge combinations will exceed the velocities listed.
Because of a wide variation in bullet diameter, chamber diameter, cylinder gap, case capacity and manufacturing variations in primers and powder, we suggest that you chronograph loads from your own firearms.
DO NOT LOAD BELOW MINIMUM RECOMMENDATIONS. Doing so could result in a bullet stuck in the bore.
Long Range Rifle Data
The loads listed in this guide are representative of common calibres used. As there are so many cartridges which could be used, only a few are shown. DO NOT USE ANY FILLER MATERIAL WITH THESE LOADS, as fillers can alter pressure and velocities decidedly. Velocities are limited to approximately 1,600 fps due to excessive leading at higher velocities.
Use flat point bullets in tubular magazines.
Any load suitable for trap or skeet is suitable for Single Action shooting. Shot loads of 7/8 oz., 1 oz. and 1 1/8 oz. are all that is required. Heavier loads generate more recoil and are, at best, unpleasant to shoot and, at worst, add time to your score.
You can find suitable Single Action Shotgun loads amongst the normal Shotgun data for your calibre and components of choice.
- Smooth shells come out of a double barreled shotgun better than ribbed shells.
- NO STEEL SHOT.
- NO SHOT LARGER THAN #4. Size 6, 7 1/2 and 8 are most common.
- CHECK YOUR RELOADS IN YOUR GUN FOR PROPER FUNCTION.
Note: Damascus barrels should be considered unsafe with ANY powder.
