[QUOTE="Marine sniper, post: 2030752, member: 4768"] Before you figure out whether or not you "need" to anneal there are a few things of relevance. The most accurate way of keeping track of neck tension is an arbor press with a force gauge. .002 neck tension with different brass prep (tumble vs. stainless media) will have a very significant impact on the force required to seat the bullet. Most of my 338's require 50-120 lbs. of force to seat the bullet. I am still testing this / what is the sweet spot. If you have your dies / FL sizing die set up for minimum expansion and sizing there is "probably" no need to anneal. I did an experiment with one of the 338 LAI. I took on piece of brass to the range with a press dies, etc. I reloaded the same piece of brass 10 times within about a 30 minute time frame and shot all rounds over a chronograph and onto the same target. The bottom line is there was no difference in velocity or impact on target. Here are the notes on that test. NOTE* I did NOT have my force gauge yet- so my thoughts on neck tension were not measured with anything more than "feel." 10 round test on nk tension and velocity re: annealing. Rounds were shot and immediately sized and reloaded. 2983 2997 2974 2977 2993 2988 2985 2981 2989 ES: 23 fps. The neck tension felt the same throughout the test- impacts on paper did not change due to number of shots. It appears there is no need to anneal with this combination. FWIW I have a salt bath annealer, Benchsource and have annealed hundreds of rounds. Annealing has it place, but I suggest testing to see if you really need to. You may find you don't need to.
