The exact amount will depend on your gun patch and ball combination and distance you are shooting, Each gun has it's "sweet spot" that is a powder charge and ball combination that gives consistent results, so you will have to experiment to find it. In my The best way I have found is to start out with as many grains as the caliber (45 gr 2F in your case) and work from there placing targets at the distances you expect to be shooting. Fire 3 to 5 shots and record your results, increasing the powder charge by 5 grains each set. Keep in mind not to exceed the maximum recommended charge for your gun, and that the key to muzzle loading accuracy in consistency, load the exact same way each time, paying attention to the direction of the weave of your patch and how firmly you pack the load. With some time and patience you will have a tack driver.
How much is a old black powder only 45 cal long barrel pistol worth?
Follow the recommendations in the owner's manual.
need a fair price of what it might be worth for an old richland arms 45 cal. black powder rifle with serial no. 2142
You need to contact the maker or get a book on Blackpowder shooting that has loads in it. Different types of weapons and projectiles and powders will determine what is a safe load.
In my short barrels I use 15 grains of 3F black powder. You can fiddle a bit with the amount +/- to do what you need, but I found it to be a good load for up to a 4" barrel.
First, find a copy of the owner's manual for YOUR pistol. Second, use ONLY black powder, or a modern black powder substitute, such as Pyrodex. The ROUGH rule of thumb is one half the bore diameter in grains of powder. A .32 cal would use ABOUT 12-16 grains of powder.
