The charges are more consistent.ĭoes trickling every charge improve results? Drops from the Harrell's are typically within a tenth of a grain. I bought a Harrell's pistol powder measure and now I use that. I formerly used a case-activated drum powder measure but I was bothered by its inconsistency and I suspected it as contributing to rolling the edge of the case mouths. I use the third solution, but I have not compared the results. I know of three solutions: a tapered steel die, Redding's Dual Ring Carbide die, or using two dies each with a different size carbide ring. Theoretically, this could result in poor or slow case sealing against the chamber wall. The cartridge will have a narrower "waist" between the case head and the base of the bullet. Because the bullet is not inserted below the seating depth, this portion of the case body is not expanded by the insertion of the bullet. If the same ring is used to size the body of the case, it will size it down to a small diameter. My Lee press is flimsy, but I can't see how using a single-stage or any other higher-precision press for these steps would produce a better result for a straight-walled cartridge.Ī single non-tapered carbide ring will size the part of the case that hold the bullet (the neck) small enough for good neck tension so there is no bullet set-back or crimp jump under recoil. I decap, resize and expand case mouths on a progressive press. Also, I do shoot at 50, 75 and 100 yards, but test primarily at 25. While I appreciate that there is a great deal more to small groups than just the cartridge, the cartridges are all this topic is about. If I could get 50-shot groups that size, I wouldn't have any further questions.
I get 5-shot groups at 25 yards that can be as small as 0.5" x 0.5". I've attempted to test a few things myself, many of which have advantages that have been statistically hard to pin down.
When we begin to pursue accuracy, we can pursue it with a variety of practices that can leave us wondering if we're just wasting time. It has been my observation that when handloaders are focused on producing a bulk quantity of ammunition, we can be efficient and productive. A desire for better understanding is what prompted me to join this forum. My goals for handgun cartridge loading recently shifted to accuracy.
