CCI Stinger was a toss-up; I mean the numbers came so close :

HP 32 gram, 1640 FPS muzzle velocity, 1124 fps at 100yds.

But technically, the sound barrier at 68 deg is 1125. With temperatures more commonly in the 70's,80's and 90's where I shoot, I figured the bullet would be dropping through the barrier a gnat's hair before impacting the target.

This really gets complicated when you start over-analyzing - the real test is in the shooting - but I read today that some newer powders - I don't know which brands or which loads - are slower burning to take advantage of more barrel length.

But, for me, I'm looking to start off with the 40 gram bullet, or the 38, just below super-sonic at the muzzle and as close to 1000 FPS at 100yds as possible. That's why the effect of barrel length on velocity is of such interest to me.

What can you tell me about the use of "suppressors" in the States. I just assumed they were flat out illegal at the Federal level?
