    Default Crimped Loads

    Will going from crimped bullets to non crimped bullets effect accuracy. The bullets are being shot out of a bolt action rifle so a crimp is not needed. I have worked up a good load and sighted my rifle in today. When I went to load some more ammo tonight I noticed they were getting crimped and before thinking I adjusted my die and reloaded a box of ammo. So now I'm wondering if my accuracy will change. Thanks for the help.

    Normally a bullet seating die will place a roll crimp. A roll crimp is designed to use a cannelure on the bullet to maintain proper tolerances in the neck. This means that the ammo you have loaded may or may not chamber, depending upon a host of factors.

    As for the specific question, I'd say that too is dependent upon several factors but the proof is in the pudding. Give them a try and relate the results to us when you do. My suspicions, so long as the ammo chambers, is that the affects will be minimal to your accuracy. I use a Lee Factory Crimp die and have had good to excellent results in a variety of cartridges, with accuracy frequently improving by measurable margins. Roll crimps tend to be more temperamental and I normally shun their use. YMMV.
