Hey everyone, new to reloading here and these forums have popped up countless times in my search for various info on the topic, so figured I'd say hi
I'm loading 9mm luger and just finished up my first test batch with a middle-ground load straight out of the Lyman handbook: 4.1gr of W231, Berry's 124gr HBRN TP, and 1.150" COAL. I'd like to try out some of their others like the Flat Point or Target Hollow Point variants but their bullet lengths are different. Do I get COAL data directly from the bullet mfr.? Berry's has COAL listed for their bullets right on the page for each one so I didn't know if that's determined by the people who make the bullet, or the people who come up with the load data.
I was thinking I just take the difference in bullet lengths and subtract that from the original COAL I was working with, so ie. going from the .612" I have now to the .534" flat points, making a new COAL of 1.072" (which is close to the 1.060" Berry's has on their site anyways). Did I understand this right?
