[QUOTE="Stevanda, post: 408815, member: 18265"] Hi All, Im about to start reloading a Rem SPS in 7mmRM and have measured 20 once fired cases (Rem cases) that came with the rifle.I have used a Sinclair Bump Gage and find there is a spread of 0.003 btween the longest and shortest case. I have read it should be around 0.001 in variation.Why could there be such a difference.Is it the bolt,the brass,the previous guys ability to measure powder accurately or something else? The longest cases (8/20) do fit the chamber with no tightness detected. Do I leave my body die alone until they won't chamber or do I adjust the die down now 0.001 on the longest cases ? I have read that excessive resizing will lead to head separation so I dont want to over do things.The rifle is stock standard with no action trueing etc but I still want to extract as much accuracy as possible. Any wisdom would be greatly appreciated.cheers Steven NZ [/QUOTE]
