Thread: different brass for accuracy

Just my 2 cents, in my Lyman Reloading manual it recommends only using one batch of brass that you know the history of for a load you've developed. More a guideline than anything I think.

I know some brass brands have differing dimensions (case wall thickness for one) and internal case capacities so it makes sense to stick with one brand or even one lot, if you want consistency accross a batch you've loaded.

However, I wouldn't say sell the other brass you have but it may not give the same results when you use exactly the same load you've been using. For example a 7mmrm load of 72.5 grains of 2217 behind a 162ELDX in hornady brass might give different pressure and as a possible result more or less velocity (and possibly accuracy) in say the Winchester brass. I guess it's just one more variable so to keep it simple, for me I try to stick with one brand of brass until its no longer use able then either get more of that kind, or whatever I can get for cheap
