[QUOTE="Pdvdh, post: 1555442, member: 4191"] I purchased 40 RWS 8x68S cases and 20 Norma 8x68S cases from Huntington Die Specialties around June, 2018. In August, 2018, I purchased 50 Norma 8x68S cases from Midway USA. Then in November, 2018, I purchased 25 more Norma 8x68S cases from Midway USA. I keep track of case weights and lengths of new cases when I purchase them, just as they're received - straight out of the boxes they arrive in. [U]This post is an update on a "lack" of consistency in 8x68S case weights between [B][I]different Lots[/I] [/B]of [B]Norma 8x68S[/B] cases[/U]. I was quite disappointed after weighing the last 25 Norma cases I received. The average case weight was [COLOR=#ff0000][U]7.0 grains less[/U][/COLOR] than the prior 50 Norma cases from a different Lot of Midway USA supplied Norma cases. This [B]WILL[/B] require a different powder charge (larger) to obtain equal velocity from these cases compared to the prior 50 Norma cases from a different production Lot. Bummer. Some members poo poo the intrinsic value of weighing cartridge cases. I ALWAYS weigh mine, and realize real benefit from doing so. Below is a table that shows the differences between the Norma 8x68S cases I've received since June 2018. One 20-count from Huntington (no production Lot Number on the Huntington supplied cases). Two 25-count (50 total) from Midway USA Lot Number [COLOR=#0000ff][B]8818[/B][/COLOR]. One 25-count from Midway USA Lot Number [COLOR=#0000ff][B]10318[/B][/COLOR]. Notice that the average weight of a Norma case from Huntingtons was [COLOR=#ff0000]10.7gr[/COLOR] [COLOR=#ff0000]heavier [/COLOR]than this last batch I received from Midway USA. If Norma cases keep getting lighter at this rate, pretty soon they'll float on water. :rolleyes: Be aware! Better than a nasty surprise. Perhaps RWS brass is worth the extra cost.
