First off, great site! What a wealth of information and informed shooters. I've been loading for about 3 years for 22-250, .204 ruger, .270 win, 25-05, and 30-06. To this point I've always followed the manuals to the letter, and used a new factory cartridge to set the die for seating bullets. I know there's a lot more to it than this, but I'm unsure about where to find good how-to's on things such as case trimming, sizing, etc. I'd like to know how seating depth should be determined by each load, rifle, etc. Before I can take the next step in LRH, I'd really like to know that I can build cartriges capable of getting the maximum performance out of my rifles. I've taken whitetail out to 360 yds using my handloads, and it's time to take the next step. I'm working with a gunsmith with the .204 (Savage, accutrigger, sporter barrel) at this time to bring my groups down as tight as possible. At this time I'm shooting around 1.75 moa (unacceptable /ubbthreads/images/graemlins/confused.gif). Thanks in advance for responses, and I'm sure each answer will lead to follow up questions.
