[QUOTE="Rich Coyle, post: 1338485, member: 70559"] I would load up about ten with a chosen powder and maximum length for your magazine. Start with the slowest one you would accept and load each [B]one[/B] with 1/2 grain more until the bolt is the slightest bit sticky, the primers are no longer rounded on the edges, or there is a scrape of brass at the ejector hole. Once there back off a full grain. Now you can check for over all length with no more than three shot groups of each length. If it won't fire three close together it won't fire more. In fact if two are not even close I wouldn't fire anymore of that length. One time I had one come in .180" from the lands with a custom barrel. Another came in at .120" from the lands. Next I would load up three of each primer I have and duplicate the above effort. Once you establish the over all length with that bullet it usually stays consistent for that bullet even with different powders. [/QUOTE]
