I had a batch of about 2500 of those that I shot 4-5 times each through the M1A. I think they're ok to reload
BUT
I think it's important that you use a cartridge headspace gage to set your FL sizing die. You want to bump the shoulder back just a little 0.002-0.003". Mine were all out of the same lot, but I had a batch that cracked at the cannelure after 4 reloads (two of them completely separated during a rapid fire string at a match--fortunately, both extracted on their own). After that, I bought a case gage and it turns out I was setting the shoulder back by 0.005-0.006". I also got nervous at that point and tossed the remaining 100 cases I had left.
I think they're ok to reload, but are more prone to separating.
