[QUOTE="VinceMule, post: 2696473, member: 122164"] We have to remember that freebore grows from the first shot fired, in some cases more than others. Say you work up a load when the barrel is new. 500 rounds later, the leade has grown over .100. With the long freebore, you can not keep seating the bullet out due to mag length. When the barrel was new, you worked up a load, you can chronograph that load. As the freebore wears, you lose velocity, then bump up the load to the same velocity as it was when the barrel was new. Often, you can gain back accuracy, but to what degree is unknown. Experienced long-range rifle smiths can offer great advice on this issue. Best to know the bullet you intend to shoot. The one twist and one throat to do it all from elephants to coyotes is a poor approach, indeed. [/QUOTE]
