With enough pressure / propellant dynamics bullets can 'bump up' and work better, but something else can come into play even with bullets sized above nominal groove diameter - Taper crimping / factory crimp die crimping after seating, where the case and bullet are 'squeezed' to a certain point, the case springs back but the bullet is left very much undersized. Worst I have seen this was with Lee tumble lube type bullets, but any can fall to this. Going to be really hard to get any accuracy from say a .353" bullet driven down a .3575 GD barrel, esp at modest pressures.Random sampling of bullets from the same lot=355"-.355.5"
Not determinative, but an indicator bullets not the problem, right?
Remember, I escaped. Or as my wife and other family members say, defected.Typical FBI response.
Just teasing.![]()
Yep all Winchester from my 17 month test--36/37 firings each. i only "kiss" to remove any flare which is seldom evident. Most could be used without crimp. Undersized & never have identified set back.Were the cases the same headstamp? Over tapercrimping is the most common cause.
This concern is exactly what I'm afraid of using xtreme plated 220gr. through my suppressed CMMG Banshee 10mmGreat comments
Large paper target stapled to cardboard backing and every few mags a new shoot n see stick on four inch center. So, no more than say 15 shots visible on center of target.
Keyholes were off the stick on by an inch or so or more.
Hadn’t thought about cracked case & beretta combo.
I don’t know anything about suppressors and hadn’t even thought about the consequences of a tumbling bullet.This concern is exactly what I'm afraid of using xtreme plated 220gr. through my suppressed CMMG Banshee 10mm
2500$ setup and one unstable bullet and disaster. Even if I test 50 rounds without the suppressor, do I fully know it's safe?
You would think the bullet would be a ways from the muzzle before it started to tumble….??I don’t know anything about suppressors and hadn’t even thought about the consequences of a tumbling bullet.
A-ha!Fortunately no FCDs were used here.
Yep, like this, never before, never since, just the one, left guessing what happened. With a very popular for 300 BLK bullet, the Speer TNT. I've never loaded them in Blackout again, but people do all the time. Set back is my guess, but dunno for sure.......Hard to find a cause after they have been shot and no other of the usual culprits show their heads.
