just tried new ammo

[rycerz]

Federal Hydrashock in .380 and I think I like it! Call me crazy but those bullets seemed to fly straighter then the Ranger SXT. It can't be that the 2 grains less really made that much difference??? Btw, I was shooting it out of the Colt Government .380.

If you have your barrel turned to 11 degree's that will fix the problem.

which problem? You mean make the Ranger SXT shoot straighter?

Sure - you have to counter the coriolis effects of the intersticial combustion in the SXT. The Colt Government and Mustang (and before it, the Star DK and the FI Model D) were were designed back in the days of Red Dot and Bullseye. The modern powders have an intergranular flame front that's totally different. You don't see it in the larger calibers, where the square/cube law increases the volumetric effeciency of the combustion chamber with a higher volume to surface ratio. You don't see it at all in .45, and you can live with it in 9mm. But in a small, short round like the .380 it can make a real difference. It's even worse in .32.

By turning the barrel and increasing the decibility above 10, you compensate for that effect.

You almost had me until you said 'decibility'

It's a proven fact some barrels will like certain ammo shapes better than others. Hydrashok rounds seem to be a little bit sketchy though - the stuff I've read/seen seems to indicate they tend to clog up easier than other HPs (which generally makes them fail to expand). When they do expand, they seem to do fairly well though.

I ask this out of my own curiosity. I have no knowledge of what is better. Anyway would FMJ not be a bad idea with a .380 round? Seem to me penetration would be key.

Here's a thought... while penetration is the key a small hole at high velocity is probably not as effective as a bigger hole

With the advent of winter, people dress with more layers.
If you shoot a round that has enough power, like a .45ACP, switching to ball might be the ticket, unless you shoot that all the time as already favored in some quarters.
That seemed to be one of the themes in Alaska.

I doesn't really matter anyway because the barrel is less than 3" and we all know that a barrel that short can't possibly expel a projectile with enough velocity to penetrate paper let alone expand in living tissue.

A kimber ultra did just that. The dude was DRT. (Dead Right There)

Do not use FMJ, use 230 flat nose.
