[QUOTE="dkhunt14, post: 1045176, member: 14053"] If throat the gun so the pressure ring or boatail body junction is ahead of the neck shoulder junction you will gain more velocity with less pressure because you gain capacity just like blowing a Case out like in an Ackley. You can go out to about half the neck but you need enough bullet in the case to hold it. When we throated out a Dasher and a 300 WSM we gained about 100 feet more withe same pressure. The WSM took about 2more grains of powder and I believe we throated it about .100housandths out farther. I can't remember how much more powder we got in the Dasher but we throated it from 104 freebore to .155 freebore. If you throat it out you also don't have to worry about a donut because the pressure ring is in front of it. Matt [/QUOTE]
