My take on mechl powder check. Yes they work, but they can, like any piece of gear, break or fail. I like them for rifle, where i cant see the charge easily, like 223. I dont worry about it for pistol because i look inside & rarely use anything like TG or BE in larger cases. If i shot a lot of such powders, then a pc die would be important & you might want 5stns.
I use 231 for my 357, TightGroup for the 327 and Bullseye for the 32 S&W Long. The charges are light and don’t take up much of the case. But the loads are nice and mild and very accurate.
I use the powder check die but like you I don’t trust a mechanical device fully. They sometimes fail. One of my powder measures when I first got it worked well and suddenly it started to throw wild charges and then none. A part broken off internally within the measure after many hundreds of accurate charges. The powder checker die caught it immediately. It works well and I can detect generally small variations in the charges. However, I still take a quick look with the swiveling mirror. All the talk about primers in this tread is a trivial matter to a squib or an overcharge.
I’ve attached a few pictures of my press with a 357 case in the shell holder. I just can’t get the angle to see inside the case without a swiveling mirror. I have plenty of light, I have a light strip and a book light. Even with all that light because of the dusting charges I use, it’s still hard to judge a double charge with just a just a quick glance. A squib yes, a triple probably but anything close to a double just maybe. Maybe isn’t good enough. I may with the right press go back to priming on the press, if it is reliable and trouble free, but I will never give up being absolutely. positively sure the charge is right.
On my last batch of 357 loads I did not clean the primer pockets. It didn’t save a lot of time but it did save some. I’ll watch the pockets to see how dirty they get after several loadings and if accuracy is affected. I don’t think that either will be a problem. Cleaning the primer pockets is more of a OCD thing than a performance or quality issue.
