I looked in the front of my Lyman 50th for an answer but it's possible I could have missed it. Anyway, here goes:
I have recently loaded some .45 Colt with 8.0 grains of unique. I am using a .452 LRNFP 250 grain cast bullet from SNS casting, starline brass and Winchester large pistol primers. The SNS cast bullets are pretty much all I have available locally without ordering from the internet
Lyman does not specifically call out the bullet I am using, but I matched mine similar to the picture. I noticed there is another 250 RNFP but it appears to have 2 lube grooves instead of one and has different powder loads for it. Does the elimination of a cannelure and 2 lube grooves make that big of a difference? I ask because they state with unique that 8.2 is a Max load and I am at 8.0. Being that close to Max and seeing the different data for same weights and general profiles is making me a little nervous. I don't want to assume anything and then pull the trigger on a hand grenade.
Basically I am asking am I ok to assume that my bullet, although not made in a Lyman mold, is safe to use with their data because it is similar? I didn't think lube grooves would affect powder charges.
These will be used in a .45 Colt Ruger new Vaquero.
Sorry if this is a stupid question or has been beaten to death, I tried searching the forum and didn't find much.
I know safety is my own responsibility and I, and only I, am responsible for my actions, but I would like to hear from more experienced reloaders than myself. I have had bad experiences in the past when I have made assumptions, and reloading is not the time for assuming.
