I resized some brass and a few were sticking, some of the ones that stuck have a little bend in the rim from the shell holder and myself pulling the press back down..will this cause accuracy issues having the rim bent some?

Thanks!
 
................and I thought this was about hitting a pothole.

It might cause extracrion issues if it's on the topside and chambering issues if it's on the base side. I've done that before on ocassion. I just take a fine file and square it if not too bad.

Need to use a bit more sizing compound.
 
Personally I toss those to the recycling can.
Before you go any further take apart your dies and degrease them with rubbing alcohol then run them through the tumbler (if you have one). Once a year I dismantle degrease and clean all of my dies just to keep a build up of what ever out of them.
 
Sounds good guys, thanks! I'll have to sort through and toss the bent ones. That's what I was planning on doing, just wanted to check.

I had slightly bent a few rims from sizing, as long as it wasn't to severe and it would still chamber I used them as my fouling shots. After shooting them they fireformed back to original specs. I didn't notice mine till I loaded them so I took a chance...
 
That would work great too! So if they fit ok would it negatively affect accuracy at distance?

In my view, depends on caliber entirely. 223's, toss, 308 (if not Lapua or Norma brass), toss. If 338 Lapua brass make do.

What I do with my dies is yearly, I'll run a small cotton bob chucked in an air die grinder up the bore with very fine finishing compound on it and then clean carefully with Stoddard solvent and blow dry. My Whidden dies are all micro honed inside, look like a mirror inside. John Whidden manufactures some super dies at a price of course. All I reload with anymore. I use RCBS competition front load bullet seaters with appropriate cartridge holders but all sizing dies are Whidden.

One nice thing about Whidden dies is John purposely makes the body short so it's easy to bump the shoulder back (without having to grind off the die base, something that was SOP for me prior to Whidden dies. He even supplies a bump gage with each die sold.

I suppose that they could affect accuracy, not being square with the boltface. I wouldn't compete or hunt with them till I fireformed them back to spec.
