9mm PCC 16" barrel velocity vs. 9mm pistol 5" barrel velocity?

[FNGGlock]

Agreed.

In terms of velocity or recoil?

Velocity, I haven't tested it in my direct blowback yet. Today was delayed blowback.

In terms of recoil, yes. If you shoot PCC class it's worth the cost to convert. Much less dot bounce. If you're just going to the range to have fun, no not worth it.

Interested to see if there is a difference in velocity.
In terms of recoil looking for something ultra soft shooting for the wife, when she wants step up from 22s

Do you ever shoot steel closer than 100 yards with a PCC rifle? Maybe 50 yards, or is that to close?

9mm PCCs are fine on steel at any distance. Guys run them as close as 10 yds or less at AP. I like to use mine to put a smiley face on a full size steel target with fresh paint at 15yds or so. Not really a challenge to do it offhand with a red dot.

This is the softest modification you can make to any 9mm PCC, and it takes about ten minutes to install.

Do any of you guys run coated bullets like Blue or Bayou in your PCC?

Or just plated?

Or just jacketed?

I'm currently using 115grn fp red polymer coated bullets with 5.3 grains of A#5.

I run cast, powder coated lead without problems as well as Federal Snytech coated lead. It all works well in my PCC.

FWIW...Here are the velocities from 129 factory 9MM loads out of my 16" Colt pattern PCC.

Wow, thanks

[sigstroker]

Cool, what's his Calguns username

I doubt he would want to have anything to do with anything kali related.

[bfoosh006]

Wow, thanks

You are welcome, Enjoy !

The difference is load dependent. If you reload or compare different loads (same bullet weight) from different manufacturers, you can get much greater velocities from a 16" barrel than from shorter ones. Testing one or a few loads doesn't provide good data to make across the board conclusions.

Take the 68 grain Lehigh for example. Getting them to 2000 fps out of a 16" barrel isn't difficult. The factory loaded Underwoods likewise show a much higher velocity from a 16" barrel than a 5". From a 16" barrel they zip out close to 2600 fps, quite a bit faster than they shoot from a Taurus beretta clone at approx 2200 fps. That is quite a difference.

The HK94 pushes 70 grain projectiles close to 1900 fps while the same load is 1600+ out of a Taurus beretta 92 clone.

The projectile and powder can make a huge difference in velocities for different barrel lengths. Blanket statements aren't really valid. Even the velocities between different manufacturers of ammo is considerable with the same weight projectiles.

The ammo makers like Federal are optimizing some of their loads for short barrels. That should tell you that the load for the cartridge (type and amount of powder/primer/projectile combo is as important in velocity as barrel length.

As she said, longer is always better.

[crufflers]

You can use that what cha ma callit, MATH to figure averages.

Take a 4" barrel and compare to a 16" barrel.

ABOUT 15% is the increase averaging some popular velocities in 4" and 16" barrels from BBTI.

99.9999% of people don't shoot that nonsense. They shoot 115/124 and some 147. Heavier bullets going slower "typically" feel softer.

[crufflers]

Glock 19 to Ruger PC Carbine or 16" AR9... 15% more is not nothing, but I always overestimate the zing a longer barrels adds. At some point all the powder is burned. You see a lot more improvement when the shorter barrel is wasting powder... like a .22 MAG in a 1" barrel.

[SharedShots]

I've heard a 16" barrel costs you velocity over a 5" pistol, so I chrono-ed my go to load yesterday.

Don't blame me, you're the one that said you heard a 16" barrel costs you velocity over a 5".

That isn't true in almost all cases.

Maybe the .0001% of the people believe what you heard.

What does heavier bullets feeling softer have to do with anything?

I provided some info on what affects velocity such as powder/primer and projectile and some things to back it up.

The nonsense is the 99.9999% number you pulled out of who knows where. You made it up.
