I have used it for 40-some years. The water capacity is very consistent, every bit the equal of Lapua cases with regard to consistent capacity. (See my testing/measuring elsewhere.) Over many lots of LC, I have used 54.6-54.8 grains of water capacity, leading to 0.8 grains less powder charge than max load in a commercial case, like Remington or Winchester. As a comparison, the highest capacity cases I have are the old Federal with the small print on the headstamp, which hold 57.2 grains of water. Current Federal cases with large print on the casehead hold the same as LC. Somebody told me that's because Federal is now the contractor for milspec .308 brass. IDK. I have turned necks, and the accuracy/precision is not enhanced, in my experience, by neck turning. Loaded cartridge runout is as good as anything, and I have shot a 0.022" 4-shot group from a Shilen-barreled Winchester Model 70 hunting rifle, using random years of LC cases. I have shot many sub-0.5" 5-shot groups with various .308 Winchester-chambered rifles, all using LC cases, with hunting rifles having lightweight 22" factory barrels up through varmint-weight custom barrels. Any case will stretch ahead of the web and separate at some point, but I don't keep track of how many rounds that usually takes. I don't want to disagree with Greg Langelius about anything, because he's rock solid. He's stating his reasons and experience, and I'm stating mine. Believe both just the same. I started with them when M1A's were the go-to rifle for highpower, and shot 41.5 gr of IMR4895 in LC cases with a Sierra 168 SMK, then I had so many cases, that when I switched over to a Winchester Model 70 Ultramatch in 1976, I just kept using the LC cases, and would (back then), increase the load until I got pressure signs, then back off. Now I can't do any competition, and just do paper-punching from a bench.
