I did not think I had to mention this, but it looks like there is some confusion over what size primers to use. Large Pistol primers and large rifle primers are not the same size height wise. Same diameter, not how "tall" they are. Small pistol and small rifle primers are the same dimensionally in every respect. If you use a large rifle primer in a large pistol case, the primer will stick above the case head. In the small rifle and pistol primers, they are the same. So what does this mean? You should not use large rifle primers in a pistol case that calls for large pistol primers even if you shoot it in a rifle. I can think of no reliable reloading manual that uses large rifle primers in a 44 Magnum. There are some exceptions to this rule. Some of the more modern hand gun cases are designed with large rifle primers in mind such as the 460 S&W Magnum. In a 357 Max and 454 Casull, both have small primer pockets. The primers are dimensionally the same size. The rifle primer does have a thicker cup so it will handle higher pressures. The 357 MAX is a high pressure round as is the 454 Casull, so small rifle primers need to be used here, unless you are going to down load them. Good Shooting and Good Luck.
