[QUOTE="Pdvdh, post: 957154, member: 4191"] Another informative post. Thanks Mike. Look's like I'd have done better to have ordered the Forster FL die with the neck honed to 0.2425"? Should have checked with you first. I don't believe I experienced the 0.001" case neck springback on my cases. If I recall correctly my sized necks - minus the expander ball - were measuring between 0.2435 to 0.244". However I don't own a tool to accurately measure the neck ID down inside the Forster die. I'm just trusting Forster ground it to the diameter marked on the die - 0.2435". I'll be resizing 1000 or more additional cases soon, so I'll make a point to measure some more neck-sized ODs out of curiosity and for comparison to your 0.001" rule of thumb. With this ammo, I was proceeding low key. I wasn't trying to eek out the utmost accuracy. It's for a plain-Jane CMMG AR15. Only reason I purchased the AR was because everyone else was and I didn't want to be without. :) Believe it or not, even with the crooked ammo produced with the RCBS FL die, this rifle shot Hornady 60gr Vmax bullets to less than 0.5 moa at 105 yds, and then again at 330 yds, on my first two accuracy tests. Just my luck. I go to great lengths to get my bolt rifles to shoot 0.5 moa and then this AR plops them into bug holes right out of the box. Wish I was so lucky with my bolt rifles - be it factory or custom. After I saw how accurate this AR was, I then decided it was worth spending a little more money improving the quality of my reloaded ammo. I haven't shot for groups since reducing my TIR with the Forster die, and I don't expect to see groups shrink much. It was already more accurate than I had hoped for. Regardless, when I measured some RCBS reloads with as much as 0.010" TIR, it was more than my OCD could bear. :rolleyes: Now that I know the rifle's a shooter, I might actually hunt some vermin with it some day.
