Hi all,
This may be a stupid question but I am relatively new to all this. I developed a successful load for my Henry BBB which took a lot of time and different powders etc using once fired factory brass. I trimmed the cases to 1.285" and maintained a COAL of 1.585". Then I decided to order some new brass, the Starline is average 1.275 and the PPU even less. What do I do now? If I try to maintain my COAL the bullet will be seated further out reducing pressure or the other way I get a smaller COAL and have the opposite. Either way the load I have been using is seemingly redundant. I am curious, why is new brass so far below the Saami spec and should I now start all over ?
