LOL easy there RR. But I agree there is some anomalies there in his little post. #1, what good is fire forming brass to ANOTHER chamber? The whole point of fire forming is to have your brass dimensions MATCHING the chamber dimensions of the rifle you are shooting.

As far as case life, that's why you anneal! Start out with decent NEW brass, fire form, neck size only, and anneal. You will find your brass will last as long as the primer pocket lasts. I find the pet load each barrel likes and load up at minimum 200 rounds for my "hunting" rifles that only get shot enough to stay proficient with that particular rifle and for my paper toys I load up around 1000. I have brass for a couple of my rifles that are on their 8th reload and showing absolutely no signs of wear. One being rounds for my AR 10 in 7mm-08 that are loaded on the pretty hot side. That WAS my longer range hog rifle (had a AR 10 .338fed built for that extra OUCHIE at 400 yards) and has taken approximately 450 hogs and a couple thousand paper shots through it. No split necks yet and zero throat erosion. You set your OAL correctly and fire form you will get less gas cutting (I.E. what causes throat erosion). Now SOME caliber/cartridge combinations are just flat out hell on a throat no matter how close of tolerances you load for like a .220 swift or any of the other large cartridge small caliber bullet combinations but you can extend barrel life through close tolerance loading and fire forming.
