To anneal or not?

I loaded my first rounds back in 1954. it wasn't until the mid1970s that I tired annealing my brass. One of the riflesI load for isa Ruger #1 in .375 H&H. I have a cast lead gas checked load that runs a 270 gr. lead bullet at about 2100 FPS Just enough recoil to let you know you've shot something. I have one box of Winchester brass that has been reloaded 20 times and is still good. Note that when reloading the .375 one needs to crimp regardless if the bullet is lead or jacketed. Crimping puts a bit of extra wear on the neck of the case. In theory, I should not have to crimp as I'm using a single hot rifle. I run those bullets over H4350 and crimp for a more regular burn.

That box of Winchester brass was loaded five times, then annealed. The next shooting of five and again I annealed the brass and so on. I don't know if I'll ever shoot something that large again due to health reasons but if I do, you can bet I'll anneal them again after the next five shots.

It all depends on the brass formula and what you want from the brass. Some won't use certain makes of brass because it's to soft. The harder you make a metal the more brittle it becomes. The more brittle it is the more it becomes prone to cracking. When i got my 6.5 prc i started with ADG brass and had cracked necks after 3 firings. I got a annealing machine and started annealing. I have some hornady cases with 20+ firings on them. With the price of brass i reload them till i can't. I bought a couple hundred of different makes of brass for it. It has really cut down on the split necks.
 
I use a BenchSource, have it all set up, then turn out the lights and spin the case in the double flame and once the neck turns a dull red, I pull it.
 
I keep seeing ads for an “AGS Custom Annealer” on Facebook, it seems simple and the price is reasonable ($250ish on sale).
Anyone used one? I’ve been thinking about buying one since I use a lot of expensive or difficult to obtain brass.
 
Since I have a detached shop with good ventilation, I use the molten lead method, which my gunsmith recommended. There is absolutely no question as to the temperature I am getting on the brass.
Dan, is that the same as the salt bath using a lee pot, I've been tempted to try that, but the lead would be much easier to get ahold of vs the salts. I may have to reach out and pick your brain a little.
