So I've been gearing up to start reloading now for about two years, but have been to chicken to actually pull the lever. I've acquired many manuals, watched extensive youtube how to videos and I've been diligent in my research, and I take load data starting points very seriously. With that out of the way, I have a few questions. I've recently discovered a local shop that seems to have EVERYTHING in stock for reloading except for a few diameter bullets and primers (go figure) and I scored 2 pounds of Vihtavuori N310. I plan on weighing every charge, because my goal with this is absolute accuracy. Can someone give me a quick rundown on N310 pros and cons (besides its expensive, cost isnt an issue when the end goal is perfection) I know that guns are individual entities and it may not like n310 or specific bullets, I've learned this from extensive .22lr precision shooting. Also, this is a load for a custom 1911 that is basically irreplaceable cost wise. Would it be stupid to buy a cheap colt 1911 to use as a "piece of mind test mule"? I also have a 223 contender I'm 100% geared up to load for, but havnt yet. Should I cut my teeth on that first to get comfortable first, or grab a 1911 in 45 to put me at ease? Or both, haha. Sorry about the rambling.
