[QUOTE="aushunter1, post: 1767531, member: 57533"] How far into the case mouth is your end seating depth, this is the question?? If you have the projectile seated towards the land so far you have minimal grip then yes it may help. But I am talking 25% or less the length of the case mouth. I have never needed to crimp, even when seating a .22-250 just a few millimetres into the case mouth. With correct neck tension even a few mm is enough but yes it would depend on the amount of recoil the rifle produces. I know from other things I have read where people are loading for say 30-30's that many people that played with crimping found it did improve accuracy. I dare say this just changed the pressure level to influence the accuracy node, but then again they have to crimp due to the tube magazine where as you don't need to. [/QUOTE]
