"Cat Sneeze" round - Just for fun - Page 2

Ruger45LC · November 11, 2013, 07:57 AM

Light loads can be almost as much fun as regular ones, I loaded up some 200gr .40's over the weekend with a whopping 1.5gr of HP38 for a flinch inducing 297 fps muzzle velocity.

^^ That sounds like a stuck slug waiting to happen. ^^

I'm not an expert, but I get concerned at anything below 600 fps.

I've taken the 40 S&W down to the high fours a time or two (lead bullets, G23) but it turns the gun into a single shot and yes I did knock a slug or two out when I dropped much below that. 600-7-- will generally cycle various autos if you stick to the heavier bullets.

Yes it was just a work up load for lapping a barrel where the velocity needs to be between 500-600 fps. Bullets defintely didn't stick at 297 fps, but I'd say it wasn't too far from it either, it certainly didn't eject the brass.

^^ It's all good, as long as you were aware of the possibility at the time. ^^

I have pulled these bullets (no fun), and reloaded them with 1.8 grains of Bullseye.

Although it's hard to measure accurately, the powder fill left about .450 space between the fill level and the mouth of the case. Since the bullet seats .330 deep, that would leave a .120 air gap.

Back in the old days, when a Squib was what the Finns call Cat's Sneeze (How did that get into the US vocabulary?) instead of a demonstration of negligence, there was an NRA article on the subject. They recommended reducing the load until you stuck a bullet, then add a quarter or half grain back. This put .38 Special squibs in the range of one grain of Bullseye, more or less depending on barrel length and tightness.

Henry Stebbins wrote ca 1964 of a squib load for .38 ACP that was accurate to as much as 50 feet but just "loosened the brass in the chamber" without actually ejecting it.
