It's not the velocity. It's the pressure. Most .30 Carbine ammo is loaded to 40,000 psi, more or less, and is intended to be fired in 18" or so barrels, in which the report is quite mild for a centerfire rifle. Cut the barrel to 7.5" and you are venting the pressure MUCH higher in the curve. Gun blast is caused by pressure venting to atmospheric, and there's quite a bit of it venting in the 7.5" barrelled .30 Blackhawk.mattsbox99":2ac5ga8g said:The .30 Carbine is a loud sucker due to the high velocity.
I have a somewhat similar story.45flattop":1i3x2jwu said:The
day I bought mine for the princely sum of $40 back in 1971 I wondered
why the original owner had traded in an apparently almost NIB gun and
my dealer didn't mark it higher considering its pristine condition.
Then I went to my local range with a friend and we shot it most of the
afternoon on and off UNTIL, in order to hear his voice I partially removed
one side of the muffs from my right ear and made the unforgettably dumb
move of turning my back on him as he decided to shoot the last two
rounds in the box of 50. The watermelon sized flame from the muzzle
in the late dusk was impressive enough but the pain in my ears was
like red hot knitting needles.
We're on the same page, same paragraph, same sentance. 8)Cape Cod Terry":1iq1zjzq said:Pop out the cylinder and see if the ejector rod is bent. It is easy to bend it if you have a sticky case and the cylinder isn't perfectly aligned. With the cylinder removed you can easily straighen it by hand. Certain batches and brands of ammo seem to be stickier than others, requiring anything from a hard push to a light tap on the ejector. Remember this is a rimless case being fired in a revolver. I put a new mainspring in mine and it solved 90% of my FTF's, remember this is a rifle primer. Great gun and a great cartridge. :D
