First as a new reloader, be cautious.
Do not trust any single source of reloading information!
Even though some feel that the power manufacturer is the best source, I do not. The reason is that I have the print out for Alliant 2400 powder and a certain 357 Mag 158 grain bullet load from the Alliant website. I put together a set of work up rounds differing in 0.2 gain increments and went to the range. As I got into the middle of my work up, I started to become concerned over the signs of overpressure I was seeing in my Ruger Blackhawk 357 Mag. I kept going as I was well below the "powder manufacturer's max and the Blackhawk is one strong revolver." I finally on a very hard extraction decided I was going to chicken out. I felt like a wimp.
I got home and pulled the powder for a bunch of cases that I hadn't shot because there were over pressure signs. I started to check around and within a couple weeks Alliant had changed their website very quitely and lowered the max powder load below where I stopped.
Again, on a new caliber/bullet combination, I try to check at least three sources for beginning load work-ups. I also look for signs of overpress and STOP at the first sign (now, I trust what I see more than what I read).
As to load work-ups on rifles like you 30-30 may I suggest a couple of thoughts. First only load one or at most two rounds if your 30-30 has a tube magazine as the number of rounds in the tube will change the point of impact for the bullets. (JUST RE-READ YOU POST ABOUT IT BEING A 30-30 CONTENDER---enjoy your handgun and disregard the lever fire comments.)
A second suggestion is to try doing a Ladder work up for the most accurate round.
http://kingfisher.0catch.com/guns/laddertest.explanation.htmlI have a Marlin 336 in 30-30 with a scope and with a load I worked up can hit 10-ring at 100 yards off of a rest. I know some guys at the gun range I belong to who use a rolling block with 30-30 in bench rest competition. The 30-30 can be one heck of an accurate round.
Good luck, have fun, but be careful and ALWAYS LOOK FOR SIGNS OF OVER-PRESSURE.
