[QUOTE="QuietTexan, post: 2453664, member: 116181"] In theory yes, but "similar" in this case means things in addition to weight like bearing surface length and the ogive radius. Same weight but drastically different other specs will make them engrave and shoot differently enough to the point where as a practical matter IMO it's best to treat each new bullet as a new project and not try to carry over information from one bullet to another. If the charge weight is several percentage points below max you can start at above a starting charge to test with, but if you've never worked with the bullet before best to start from a more conservative place, and run the full ladder so you don't miss anything. I don't necessarily use slow nodes, but it's nice to know they're there if you can't find a fast node. You can always check the slow node and confirm a bullet does shoot well somewhere, just not where you want. Back before Nosler redid their website there was a disclaimer on the ABLR page to use book COL as a starting point because so many guys were having trouble with them shooting poorly sat out long. My 300 RUM shot the 210 ABLR best at the book COL spec of 3.600", which was 0.072" off the lands in my rifle. Even though that sat the base of the bullet past the neck shoulder/junction, which is another bit of conventional wisdom that didn't work in that case. [/QUOTE]
