Yeah, semi-hot loads are tolerated in most modern revolvers. Some longer than others. Most reloading manuals have a "Ruger only" section. Refer back to the earlier posts regarding S&W's .357's built on K frames. A steady diet of factory magnums usually resulted in the top strap bowing up and turning them into spendy boat anchors. It's when you get into the realm of compressed loads that, "Oooo...that's gonna leave a mark!" at least. But 99 times out of 100, we're talking about rookie reloaders.  Chuckle "Yes my dear, you can blow up a Ruger!"

And like you mentioned, underpowered loads can be just as dangerous. Squib rounds can lodge the bullet in the barrel and firing another round behind it trying to clear the blockage is another recipe for disaster. I can't remember the make/model. But not long ago, somebody did just that. And when they sent it in for repairs, they discovered like 4 or 5 bullets lodged nut to butt in the bore.  Chuckle Probably WWB 130gr .38's.

But to their credit, Winchester caught this one and we're discussing it.

Thanks for that memory jog! The example I was thinking of was a revolver. But how's that for some positive High Point PR???

But to their credit, Winchester caught this one and we're discussing it.

Let me explain what happens when you fire another round to "clear" a similar bullet lodged some distance down the barrel. A little basic physics and some knowledge of interior ballistics will help. Consider a bolt-action 22LR rifle with a 24-inch barrel. For some reason a 40-gr. lead bullet is lodged about 18 inches up the barrel. Most 22LR loads achieve maximum bullet speed, say 1200 fps, after 9 to 16 inches of travel through the barrel.

When the second 40-gr. lead bullet is fired, a column of air is trapped between the two bullets inside the barrel. Let's say an initial volume V0 of air at a temperature T 300 degrees Kelvin and 14.7 psi pressure P is confined between the moving and the stationary pistons in the cylindrical bore. According to the Ideal Gas Law

P*V = n*R*T

We can ignore the physical constants, n and R here. When the second bullet has traveled 9 inches up the barrel (half way to the barrel obstruction), it is moving 1200 fps. As an adiabatic compression, the absolute temperature T has doubled to 600 degrees K, and the volume V of the trapped gas is one half of V0. So, the pressure P of that trapped gas has increased by a factor of 4, to 58.8 psi.

When the bullet has traveled another half of the remaining distance (another 4.5 inches), this doubling of the temperature and quadrupling of the gas pressure repeats again (1200 degrees K and 235 psi). After another 2.25 inches of bullet travel, the temperature of the trapped air is 2400 degrees K, and its pressure is 941 psi. This pressure is still not high enough to begin seriously slowing the second bullet.

After three more iterations, the two bullets are only a quarter inch apart, the gas temperature is 19,000 degrees Kelvin, and the gas pressure is 60,000 psi. By now the second bullet has slowed to perhaps half its maximum speed. The stuck bullet is now beginning to move forward, as well.

Finally, when the two bullets are within an eighth of an inch of each other, the gas pressure between them reaches 120,000 psi, and the barrel steel exceeds its elastic limits (fails). The second bullet momentarily stops moving, and the stuck bullet exits the barrel at perhaps 900 fps, followed by the second bullet moving very slowly. At the very least, the rifle barrel has a noticeable ring where the first bullet was lodged. As you might guess, many variations of this process can happen. My point here is that compressed air between the bullets does the damage, and not the propellant gasses driving the second fired bullet. High-speed ballistics research guns have actually used this phenomenon to fire light-weight projectiles at speeds between 5,000 fps and about 15,000 fps. A conventionally fired heavy piston compresses a light gas like helium trapped behind an aluminum/teflon projectile. Otherwise the conventional propellant gasses themselves do not exit the barrel at much over 6,000 fps.

Almost any barrel obstruction in the muzzle of a high-powered rifle will "banana peel" the muzzle end of the barrel if another round is fired. Many hunting rifle barrels are shortened to remove this type of damage. [I have had to do several for negligent customers.] Always run your fingers carefully along the outside of any second-hand shotgun or rimfire rifle to check for barrel bulges or rings.

Prime is right of course... Though a tad long winded LoL..

For those not wanting to read all that, it boils down to one simple math equation...

Bullet behind squib load in barrel = face full of shrapnel!!!

Dont DO IT dipshit! Dont do it now.. Dont do it years from now when bullet "technology" has advanced.. dont do it tomorrow cos youre in a hurry... DONT FRIGGING DO IT. EVER.

Now.. that being said... What RA said about the barrel with 4-5 rounds in it? Yup.. Its story that IS going round. Whether is a STORY or a MYTH I dont know... But as for make and model, it was supposedly a Hi-Point carbine. And as per their warranty, it WAS fixed and returned..

Shrugs... I guess if someone was interested enough, they could always call hi-pint and ASK if the story is true.. All I know is that is was supposed to have happened with one..

Wow... Missed that... But WTF??? 35? How the hell do ya not notice for 35 rounds? Had no idea it was that many. Jeezzee... These things only have 10rnd mags, 20 for some aftermarket... So they had to of even changed mags at least once!

Facepalm

I don't know what he was shooting at but he must have thought his sights were off.

Do any of you have any experience with PSA rifles?

I've wanted a pcc for a while and this one has my interest. It takes Glock mags.

A friend has one in .300blk. AFAIK, zero probs.
