[QUOTE="Vleder, post: 692368, member: 27841"] Hi all I have recently had some very dirty cases after firing, black powder all over the case and down to the rim, not all the cases and not all the same measure of dirt but nevertheless not what I expect should happen. Have spoken to a few gents and could be neck tension problem, lube on cases, dirty chamber, low pressure etc. Herewith my details so if anyone has an opinion please feel free to guide me as well: Redding match type s dies with nitrade/carbide bushing, .335 size. Lapua cases, 308 win, Nosler Custom Comp 155g bullets, 42.2g S335 (local powder), COAL 2.860 (measured to touch the lands at 2.883). I am also using the match seating die from Redding. Do not think it is low pressure with the given load, this did not happen with lower charges of 41.5 tot 42g and slightly shorter seating depths (2.850). I want to try a smaller (.334) bushing and see if this improves the situation but I suspect as my other loads are not showing this problem that I might be the culprit with a dirty chamber and not properly cleaned (resizing lube) cases before firing. Anyway, here's a pic of the offending case, this was the worst one, not all looked like this, thanks for any advice guys. [/QUOTE]
