[QUOTE="Bullet bumper, post: 921971, member: 17844"] The thing is that if you work up a load with a crimp and then don't crimp , it is going to change things. If you work that load back up without a crimp it may shoot better than the original crimped load . Just swapping back and forth between a crimp and no crimp is not the best way to compare the two because the load has been tuned for only one . The only good way is to work up two separate loads , one crimped and one not and get them shooting the best you can and then see which one shoots best . You could still end up with no clear winner though as far as accuracy goes . However if the use of the ammo does not require a crimp and the accuracy is equal or better in the non crimped round then I would prefer the non crimped ammo for reasons other than accuracy. Avoid a crimp if you can . I don't think it's got anything to do with the type of action or the chamber . I think it is related to changes in neck tension , pressure curve changes and seating concentricity changes . I have a Mauser that shoots well with uncrimped ammo but then again I have never tried crimping in this gun either . [/QUOTE]
