I anneal every 7th firing, with all the brass I shoot. I have cases with over 80 firings still going strong. I'm neck sizing, then only full length sizing when the case doesn't fit in the chamber properly. Even with my AK I neck size only. I don't think you can anneal too much; a lot of people anneal every shot because they believe the exact same neck tension will translate into smaller groups. They could be correct; I'm satisfied with under .5MOA with my scoped rifle, I'll usually get around .33MOA.
Also... I have found some new cases need annealing after just a few shots; therefore, I'll anneal if I find a case has lost its ability to hold the bullet as securely as I deem necessary.
Excellent info, thank you! Based on just the limited reloading I've done thus far with .300 and 6.5 Creedmoor, the .300's are WAY harder on the cases vs 6.5 which is really easy on them. The .300's obviously require more work so I really don't mind the extra time to anneal more often, just wasn't sure it was common as what was out there for info. 6.5's are a pleasure to reload because they are so easy on the components and the wallet.
I've found with my rifles, hot loads are the deciding factor. If my loads are too hot, I need to full length size periodically; if the loads aren't hot, I never need to full length size and the cases keep shooting and shooting and...
I like shooting the 30-30 because of cost also; especially now that I cast my own bullets.
