[QUOTE="WildRose, post: 2442663, member: 30902"] I've done very well for myself so far with Redding S type dies. I load for a .260Rem AR though and found that using the Lee Crimp die gave me the most reliable neck tension and prevented rounds from "walking" on me in the mag or getting pushed back into the case trying to cycle from the magazine. Nearly all military rounds are crimped to avoid those issues. On my bolt guns I run very lose neck tension to the point I can load bullets with just finger pressure and then apply a light crimp for consistency and to keep them properly seated for length. You can't do that however with any sort of compressed load or they'll eventually walk out on you even sitting in an ammo box.😂 When I was first playing with neck tension I was also running some loads that were rather somewhat compressed in the .260, 300wm, and 7mmSTW and when I went to load them up a few months later found some of them had grown by a 1/4" or more just sitting on the shelf. I then understood why some of the competition shooters that ran loose neck tension would only do their final seating at the range right before or even during a match. [/QUOTE]
