The constant in my reloading is Unique-I started with it, and have never varied, as far as hand guns are concerned. What has changed, as I have learned, read, and experienced, is bullet type, and weight, including bullet hardness. But I would have to say that suiting a specific bullet to a specific gun has recently been the thing that has yielded the greatest rewards. The critical element in suiting a round to a gun-or possibly 2-3 very similar revolvers, is cylinder throat size. Once that has been found, the type, weight, and hardness are next, followed by how I seat the bullet, and the crimp applied. Once I have those facts on hand, then the ammount of the charge can be ascertained. When I started loading, that process was almost reversed! The satisfaction that results from this approach makes shooting a fine handgun what it is suposed to be in my view. Recently, the thought ocured to me that it would be difficult for me to buy factory ammo, knowing what I have learned, and I'm certainly no expert. But the only constant from the beginning has been Unique, and I think that has made learning the rest of what I have found simpler. Flapjack.
