I do feel one can get by just fine by annealing after every 3rd firing. A lot depends on just how much work is being done on the brass when it's being sized. Have the sizing die's neck honed so that the neck of the brass isn't being reduced by .010 or so then expanded out by .008 can help a lot with that. I have my sizing dies honed to .003 smaller that where I'll be expanding them to (this too depends on variations one might have in the brass being used). In any case, yes. . . I like annealing after every firing.Thanks for the extra help. I admit, primers are seated by feel using the RCBS automatic bench priming tool, so maybe I need some schooling on that. I stop when I feel them bottom out, and don't crush, then run a finger over to make sure it's just below flush with the case head.
I initially was using Winchester WLRM in the 338 years ago, but got better results when I switched to the 215M. I haven't tried others.
I'm heavily invested in Retumbo, but you may be right. I sure hope you aren't !
The batch of 300PRC brass (200 pcs) is currently finishing up their second firing, about to process for their third. I recently got an AMP and intended to only anneal after every third firing. Are you a proponent of annealing every firing?
IMHO, that Norma brass could be a big part of the issue you have in getting your SD's where you want them. I do think they can be worked and sorted to get you there, but's it takes a little work.The batch of 338NM brass (250 pcs) is currently finishing up their third firing, and I mis-spoke. It is Norma brass. I have some new Lapua brass for it on hand, but forgot I was still using the Norma right now (Lapua wasn't available in 338NM when I acquired the Norma brass, but is now). I have nothing but Lapua brass for all my other cartridges (338LM, 300NM, and 300PRC), so I somehow forgot that I haven't actually put the 338NM Lapua brass into service yet since Lapua is all I normally use on everything.
Yeah, I got the Garmin then also. It's the cat's meow for now. Before that I had gone with with MagnetoSpeed v3 and have been waiting for affordable technology that works well to come along.Garmin chrono ever since they first came out, Labradar for 6 or 7 years before that, MS3 for 1 year before that, and a couple different optical chronos (ugh) going back to the dark ages when that's all there was. God Bless you, Garmin...
