Here I would like to share a recent experience with an ammo customer and the details of his success story with our help. This gentleman shooter has a fondness for antique arms and enjoys shooting them but only shoots black powder in them.
We have been loading BP ammo for him for about a year now. He is the type of customer every business likes, dependable and steady. For the most part he has been quite satisfied with the accuracy of our BP ammo in his rifles. Recently though he let me know of his disappointment with accuracy of ammo we supplied in 40-65 wcf for I believe a Ballard rifle.
He admitted that the condition of the bore in this rifle was rather poor with lots of pitting and dark grooves. We had loaded his ammo using an original Winchester mold marked 40-82 to make the bullets. This is the same bullet design Winchester used for the 40-65 a 265gn flat nose plain base and some molds were marked 40-65 for the same design.
He asked if anything could be done to improve accuracy and I suggested since we have a nearly identical design but with gas check base that he try a gas checked bullet. He seemed confused by the suggestion and felt that a gas checked bullet may compound the situation as it may resist obturation of the bullet base. I explained that for this type of situation I anneal the gas checks first before installing them on the bullet base so they do readily expand with the bullet base to make the gas seal but also add shear strength to the bullet base to better hold the rifling and not slip.
I likened the bullet to a stuck bolt and the rifling to a well worn socket wrench. The soft stuck bolt (bullet) might be stripping in the worn socket but crimping on a harder surface to the bolt may allow a better grip and not slip. With a gas check on a bullet base once both have entered the rifling the lands cause a mechanical attachment of the check to the bullet creating in reverse the rifling pattern on the inside of the gas check cup to grip the bullet base. This mechanical grip increases the shear strength of the soft alloy and allows the bullet to tolerate the required torque to keep the bullet in sync with the rifling.
He seemed to accept this explanation and was willing to try some ammo so loaded. He contacted me the day he got the ammo as he was anxious to try it to see if there was any improvement in accuracy. He was very please to report excellent accuracy with the ammo using the annealed gas checked bullet even though the fuel was black powder.
This is another example of finding success by moving beyond the confines of conventional wisdom. I am so glad this worked a treat for him with this less than stellar condition rifle that seemed perhaps might be relegated to wall hanger status. I also have to admit to maybe being a little puffed up about being right because as Tina will gladly share that is not always the case.
