Gone thru a lot of 38spl & 357 brass over the years. Never bothered with using brass only VS nickel plated. Right now I'm culling out my old 38spl brass working on a 2000 piece batch of 1x nickel plated ww wc brass.
Best 38spl brass cases I've ever used was the old 1x wcc brass that could used to be able to buy up at camp perry. It's thicker then normal commercial brass and had a extremely consistent neck tension.
Most on my 38spl/357 brass never makes it until it splits & when I do get cheep/use the brass too long it usually comes back to bite me in the butt. Culling them when they start to look warn/beat up (because they are) or when it takes little resistance to size or flare the cases ends with them getting tossed in the scrap bucket.
Used to shoot tons of 357's every year and got away from using mostly 357's and started back to 90%+ of the range time with 38spl reloads. Hence the 2000 1x piece lot and culling out the 38spl cases. Well I bought a nib 686 a couple years ago and started working up 38spl & 357 loads for it. The 1x 38spl brass shot bugholes @ 50ft.
More then happy with those 38spl/6-shot groups @ 50ft with the new revolver. Started working up 357 loads an kept getting groups like these @ 50ft.
Didn't matter the powder/bullet/load, kept getting fliers. Took a hard look at the 357 brass I was using and ordered 3000 pieces of new starline brass that night. Ended up culling/tossing most of the 357 brass and putting 2000 pieces of the new starline brass into service. Sold the other 1000 pieces several moths ago on this website for what I paid for it (no gouging) trying to help others. Anyway with the new brass the fliers went away.
At the end of the day the real question becomes are you better off using a brass that cracks fast or lasts forever???? The nickel brass cracks fast but holds a more even neck tension thru out it's life. Or use brass cases that last +/- 40 reloadings and put up with fliers.
Look familiar? 25yd 6-shot groups @ 25yds using brass 44mag cases.
Yup a whole pile of them with 4 or 5 shots touching and the 1 or 2 fliers.
Needless to say starline go a call for 2000 pieces of new 44mag brass 5 years ago.
