how much of accuracy improvement could one expect from annealing. The farthist would be no more than 300 yards.

IMO, Annealing is to let you load, without splitting cases, will help with sealing chamber. Are you using a heavy crimp ? You do not say what you are shooting or reloading ? I see very little plus on the accuracy side, other than to use old tight brass ?
The accuracy may not have been improved much if any, the benefit is a consistent batch of brass. A batch of brass that is consistent, used in addition to all else needed to develop a load, contributes in overall improvement in accuracy. It's just one step in the right direction, and it allows you to achieve more loads per casing. I anneal my cases every 3rd or 4th use to extend its life, others may do it every time they shoot, each to their own. I just shoot paper nowadays, just for fun.

What is the most about of reloads you have gotten out of a bottle neck case?Quote:

Check the F-class and Benchrest gang, and their views on annealing (which they do after EVERY firing). It promotes consistent neck tension.
To answer this question we kinda gotta know how you define accuracy. If you’re shooting pie plate size groups at 100 or 200 then annealing won’t help.Quote:

I'd always heard annealing was to help keep the necks from splitting.
If your brass is otherwise consistant I doubt you'll see any difference in practical accuracy
until you get off into a serious bench rest rifle, and high end/match everything else.
I really don't know as I just don't shoot that much anymore, I just throw them into the scrap pile once the necks split. Record keeping is not my thing. Others might be able to chime in on their findings. I built my annealing machine and annealed several hundred .308's shortly thereafter. That's enough to last me to the end.Quote:

No crimp, Mollied bullets, fired and single loaded rifle, would fire 100/200 per week, more when he was competiting, started with about 1000 brass and had most of it when he stopped shooting that rifle, even primer pocket stayed tight on all most all of it, that was the only reason we culled some. He set 4 national Reckord's at 500 or 600 yds with that rifle.Quote:

Neck tension is very important but probably only perceptible in guns shooting F class or bench rest where the rifles shoot sub .2 MOA. F class and bench rest shooters get good at this or they stop doing it. Where annealing helps most reloaders is in improving brass life and shoulder spring back making a neck sized case increasing difficult to chamber until the shoulder is bumped. It may also be needed to soften the brass to form a new cartridge from a donor case or if you full length size a lot especially if the chamber is large and the case is being FL sized a lot. Just remember with annealing you can do just as much damage or more than good if not done right. If done right it can substantially extend brass life. I have full power loads in a 220 Swift and 243 AI where the cases are 20+ years old with over 20 firings and not perceptible thinning of the brass inside case above the web. When staring out work on consistency and error on the side of not annealing enough. You can always anneal some more but you can't un-anneal. Plus, if you over anneal to the point the case head is softened, it become a safety issue.
Annealing done right may not greatly affect accuracy, but what it will do is increase case life, On expensive or hard to find brass this is a plus in itself. It will improve consistency as the case hardness affects spring back. It improves the case seal on the chamber
On brass with a lot of prep work increasing the life of it is good. Ive also found when neck turning or reaming it may improve surface finish
I only anneal the 300 BO cases I form, and I only anneal them once. My experience is that seating depth is inconsistent (.005 +/- ) with un-annealed cases and very consistent with annealed cases which I attribute to consistent neck tension. Accuracy remains a work in progress for me.
