Re: case inspection

To further muddy the water, the 'bright ring' can also come from a F/L reloading die.

Re: case inspection

i can actually feel the bulge on the bright ring, and it seems pretty consistant with most of the 270 rounds as far as the bright ring and bulge placement. The bulge does not circumvent the case. Also there were several with backed out primers, cracked necks and grab dents in the rim. I will saw one in half to get a confirmation view of it.
Like i said, that 270 was stolen, so testing the rifle may be up to the culpret.
After flipping through most of his notes and books and stuff, i think it's safe to say he put a lot of round through that gun.
NOW,
with that being said,
would 53 gr imr 4350 w/150 gr speer sptz w/winchester case in a model 70 w/20" bbl normally display that amount of stress to a 2-3 reloaded case?

Re: case inspection

I agree that you should not shoot any of the hand loads and pull them all down . If you don't know for sure what the powder is , dump it an use new identified powder.
If you don't hand load then find somebody to pull them down and just keep the case and bullet till you do hand load.
I refuse to shoot anyone else's hand loads it is just too risky .
A good tool for visual internal inspection is a Doctors Otoscope , one of these Pocket PRO LED Fiberoptic Otoscope NO Burned OUT Bulbs | eBay

After some experience with it you can see thinning of the cartridge web starting as a black shadowed ridge right where cases always go.
If you section a few cases over time and inspect the progress of thinning add to that the amount of times already fired and you can build up a mind picture of how much thinning is associated with the look of the Shadow and you get a good visual idea of when they need to be replaced.
I find this more reliable than using any type off feeler to gauge the web thinning as I can't feel it properly and one side could be worse than the other and you miss it , sectioning a few would also help with learning the feeler operation but I like the visual way better , you can see all the inside of the case and check for burrs , pits, cracks and flash hole irregularities when they are new . It's like using a mini bore scope and also great for inspectiong dies .

Re: case inspection

My take on shooting someone else's handloads (with 2 exceptions) is this....

Shooting someone else's handloads is like cheating on your wife. You may be a good liar but sooner or later you'll get smacked....bad.

Thye 2 exceptions for me are, one handgun loads with hard cast lead pills loaded by someone I know and 2, I load for our entire group, they all shoot my handloads in 223, 308, 270, 22-250 and 338 Lapua. However, I'm very methodical about how I load, what I load and everything is carefully tested and recorded in each box of rounds. Best part is, I get each of their rifles to build loads for so I get to shoot lots of different brands and calibers.

I leave nothing to chance, I use quality brass (usually Lapua brass), quality propellantts (usually Hogdon) and quality pills (usually Sierra or Hornady) and cases are inspected each and every time and annealed if necessary or pitched in the scrap can.

The last thing I want is to betray the trust of anyone in our group and/or cause personal injury. These guys are all my good friends and I value their friendship both hunting and not hunting.

Nobody can inspect a case properly from photos on the net , asking the right questions is good but you have to develop your own case inspection skills in the end . I showed you a good tool to start doing that .
