I reached a point of the ultimate nightmare. CCI large rifle magnum have become as rare as a virgin in a whorehouse. When I went to winchester primers the results were not comparable. That occured as I completed a 1 lb can of H4350 and hornady quit making 175 gr interlock round nose bullets.
For this many variables I'm back to building a ladder on 0.1 gr increments to see if I can re-establish the consistancy I had for 45 years with differant parts.
I’ll see you and raise you having to pack up my entire reloading room because we are putting house on the market.I reached a point of the ultimate nightmare.
Loaded 50 rds of 7-08 to go shoot steel and started a load work up using some CCI250 primers rather than 200.
I want see how the ES/SD is affected with the superformance powder.

Please report back. Curious about that powder with both primers
Ugh. That sounds like a slog for sure. I love shooting them, but bulk prepping handgun brass might be the most monotonous task in all of reloading.cleaned and and sized 500 cases of 10mm. Next week I'll load them. I really need a progressive press but I just can't seem to part with the money for one so I just work through it.
The magnum primer in that case could be contributing to the pressure signs, that's a fairly small amount of powder to be igniting with a magnum. I usually get more consistent results with regular large rifles, I'd bet you could add a grain or 2 of powder back in if you had the room and switched to a regular large rifle. The rifle seems to like that combo though, looks like it shoots pretty dang good.I’m trying the 250s to see if the magnum can get the ES/SD down. I’m finding that with a less than full case, the ES/SD goes up. But, with a fuller case using a book max charge, I get pressure signs
The pressure was with a LRP at book max. I've played with the seating depths and get more pressure/velocity and higher ES/SD with the bullet seated out long. I backed off the load to try the MLRP but seated at a depth that has been yielding good consistency.The magnum primer in that case could be contributing to the pressure signs, that's a fairly small amount of powder to be igniting with a magnum.
