[QUOTE="boomtube, post: 236679, member: 9215"] The book OAL is no more a "law" than the powder charges they list. It's just the OAL they used to develop the data for their guns. With handguns, it's frequently established by the crimping groove. Since we must develop our own chages, using their data as a guide, our specific OAL differences don't matter any more than our barrel lengths IF we start low and only move up if there is no reason to stop. If the OAL works through your gun without excess pressures, you are okay. It is uncommon for sporter rifles to shoot their best with the bullets touching the lands. I find a set back of .030" or more from the lands is usually better for accuracy. [/QUOTE]
