[QUOTE="Gene, post: 288260, member: 7402"] All the above suggestions are very good. However, I prefer to find a bullet, primer, and powder load from the manuals and start with an OAL that will fit the magazine or is at least .030" off the lands. Start with a powder charge near middle of the load table, load three of each moving up 3 grains in each case, stopping just below the maximum listed. Choose the best group/load from those targets. Change just one item with each step. Now that you have a good load, think about the OAL. How do you know when the bullet touches the lands? There are several methods. You can buy an OAL comparater like the Hornady, I use the Davidson (sold by Sinclair) nose and base set with my caliper. The bullet tip will not touch the lands. These tools show you where the fat part of the bullet (ogive) touches. Shine a bullet up with 0000 steel wool, Seat this bullet out nearly to the manual suggested OAL in an empty case. Insert in the chamber and extract it, look at bullet with a magnifing glass. You should see several marks made by contact with the lands. If none, it means your Oal is too short and the bullet needs to be seated longer. Pull the bullet, shine it again and repeat this process increasing by .010" each time. When you can see the engraving from the lands, back off seating at least .030" load three at that length and three more .005" longer, then three more another .005" longer, etc, until you have about six three shot loads to test.
