Cool old boxes.
As to a vibratory cleaner setting off a round, I’m sure it’s happened but I can’t imagine a rounds tip having enough momentum to hammer a primer. Guess it’s possible. I dump them in by the 100 for 223 that is going into ARs since the lube can cause grief in cold weather.
I think the reason you didn’t see much difference from 71.7 and 72 is in the overall capacity of the case you’re less than about 1/2% probably even less. I’d incrementally keep creeping up in .5 grain increments. Your accuracy looks pretty good to me, so creeping up in charge weight should get...
For me it’s finding the charge that’s happy with a certain bullet weight. My neck tension may help since I do use a lot of bushing dies or Mandrels to keep that consistent. Also great brass helps a lot since it is consistent from shot to shot. Certain powders really shine in certain cases as...
Same as the others. I’ve used Hunter which is RL19 like in burn rate, same as H4831SC up through RL26 and even Retumbo with heavies. H1000 and 105’s is about as stable and accurate as it gets.
I have a few old boxes of 303 Savage somewhere in my mess. Think they were Remington white and green boxes but don’t hold me to it.
Great pics. I’d be tempted to put them old shells in a vibratory cleaner and see if they polish up.
I’ve been using PTs on and off since I was a kid reloading at 13-14 years old. I’m 48 this year. I’ve never struggled like you mention to get inch 3 shot groups with them. Sometimes no matter what I do I can’t get them smaller but MOA is really, good enough in most cases.
I’ve notice PTs have...
I doubt you’d notice too much difference out to 200 and likely further just using a BC that’s “close”. If you shoot longer you can reverse engineer and get an accurate BC if you ever needed.
