https://www.warner-tool.com/wp-cont...rma_198g_26datasheet.pdf?13658474175506198443 I'm using these 198g warner flatline bullets in 300nm. they did the courtesy of sharing quickload calc which i've linked above I started with berger hybrid target 230g and 84g of H1000 and walked it up to 86.5, where i got pressure and stopped. that was 3045, 3043, 3048, 3028, 3035 fps. I also shot 86.0g and got 3010, 3010, 3010, 3008 fps, which is dang good imho. but again, i want to work up a load for the warner flatline. I bought a pound of R25 and R26. Based on quickload, i'm going to start with R25. quickload says max load (i assume) is 86.41g, which should give 3204 fps. I don't want to run hot loads, but i do want to find a node as close to max as I can. Almost all my experience is with cartridges in the 37-47g weight, so i'm soliciting suggestions on starting charge and what increments to go up, to find nodes. would you really start 10% down at 77.77g? maybe 78.00g and go up in half grain increments? third grain increments? whole grain increments til i find pressure and back down in third grain to find a node?
