basically what the top says. i use remington HP and they work ok switched to cci standard and they were very accurate but they dont feed well in my 597. i use mini mags also but they get pricey. looking for something around the 25$ per 500 that shoot as accurate as the cci standard
I can buy CCI minimags or standard locally for $6.95/100, which is $35 per 500. Is the extra $10 that big of a deal-breaker, or are prices not so good in your area?
Maybe a local shop would cut you a deal if you bought 500 or 1000, and get the price down a little bit?
ETA: My guess is that prices aren't that good in your area. The bulk stuff I saw today was about $14-$20 per 500, depending on brand. Hmm... do Remington subsonics work well in your gun? I see them quite often for $3/50... that's a little closer.
