Stainless Steel 455 Bore Pitting ?
« on: November 01, 2024, 03:08:28 PM »
Hi - I have a 2017 CZ 455 SS Lux that I bought USED with ca-500 rounds thru it over 2-years ago. At the time I B-scoped it and saw this pitting and what looked like 'lead-glazing', but it shot quite accurately (for me) so I didn't worry. At this point I'm still wondering if this is a common condition or just the result of 'poor maintenance' by the OEM owner. I'm wondering if this is a large buildup of lead or just pitting and initial 'seasoning'.  It wasn't 'super-clean' when I bought it ? I've cleaned with Hoppes-9 and C-4 and even Vinegar/H-peroxide, and have it looking good but I'm still wondering . . .
Any opinions/information on this? Here's pics of the bore, just cleaned recently ( 10/29/24)
First Leade & first rifling, then mid-bore. Looks like this throughout the bore.
PS - It still shoots in the .3-4xx with SK-RM. And ca 2500 rounds fired.

EDIT - I've added bore-pics from 2022 since my question was focused on the cause of the pitting, not how it related to accuracy. This will never be a competition rig w/o major upgrades that won't happen. In these older pics there is a noticeable 'shiny' look to the bore especially. Is that from 'leading' or just because the first owner didn't clean as well as I do and the pits were 'filled in back then? Anyone with experience with CZ-22LR SS bores ?
