+P benefit.....3.5 barrel?

[jocko]

might givealittle more pressure but IMO I see no harm no foul with alittle set back. If it bothers u alot, then ur gonna have to make some changes for peace of mind. MY PMJ9 is always fully loaded in my home. No kids so it sits on the mantel at night andis the first thing in my pocket when I walk out the door..

Nah, wasn't too worried about it from a safety standpoint. I ran across the whole 'setback' concept years and years ago and at the time couldn't find one single instance of someone claiming it had caused them a problem or a hard instance of it being determined to have caused a safety issue or failure of a firearm. So, I called 'old wives tale' on it back then but at the same time erred on the side of 'what if'.

Mostly, it just came up b/c of the CD round and how much it seemed to be setting back in guns I've shot a ton (P9 and TP9) and had never seen before in other ammo. Coupled with the fact that Hornady actually has some 'marketing' info on this round that claims to deal w/ 'setback'.

CANNELURED BULLET WITH CRIMPED CASE ensures no bullet setback during feeding.

Granted, maybe they mean during standard feeding, i.e. ONCE. But dumping a $.75 - $1.00 round at about triple the frequency of my old PDX1 carry round kinda pissed me off at first. But I'm over it.

I recently did a setback test w/Critical Duty using my SIG P290RS (2.9" bbl). It took 25 chamberings of the same round before I could measure and visually see any setback (appx .01", crimp still within the cannelure).

That's interesting. I'll have to try 25 w/ my CZ P-01 and see what happens. Then do 25 with my TP9. I predict a DRASTIC difference.

Check some of the data here. Ballistics by the Inch tests a lot of ammo in TC barrels that are cut down inch by inch with documented velocities. The last cartridge is my favorite carry round the+P 124-grain Speer Short Barrel Gold Dot. They also include some real world pistol tests and velocities.

+1 on that load. Different burn rates are used for short barrel apps., larger mouth on the hollow point too. I would trust some of these engineered loads in our shorter barrels than just some standard +p loads. Just more physics behind the design.

criticalduty IMO copies the corbon power ball, which has been around for awhile. One nice thing about both and I think the powerballeven does betteris they feed like a fmj round. asu know if it won't feed, then it isn't worth a cold bottle of piss. Not sure the BG will notice mucyh difference in any good defense round but first of all it hasto exit the barrel.

To many good rounds out there and ur logic of what most leo's and depts use should be a great guide to most all shooters.I never paid much attention to theis 3" or 3.5" or 4" bbl test, It is whatit is, not like ur gonna shott a BG every day, so find a good round that shoot totally reliable and is accuratge for your gun and screw the rest of the stuff. 99.9955% of all of us is never gonna have tofind out what kind of penetration we got on a BG either
There are just a ton of great defense rounds on the market, some might be over hyped but most deliver as stated to..

We have some good members here who have done some nice tests so I choose not to knock their work, but I choose to make my own decision to...

Only if u conider speling, grammer, and punction important; could i hav sad it beter myselve Just sayin..

It's a numbers game. The only way to know for sure if standard, +P or +P+ is the best is to shoot something living with it. Since Jocko owns a PMJ9 and a herd of goats, I think he's our go to guy. C'mon Jocko, quit shooting the bull, or in your case missing the bull and ventilate a few goats in the name of ballistic science. Curious minds want to know.

[jocko]

ur a sick bastard muggs. Just sayin. I have been into sheep this past year (figureaatively speaking though). My goat herd is down. Lots of serbians around my area and I think they have been rustling my goats.

[muggsy]

The way I see it those Serbians goat rustlers did you a favor. Sheep are much better companions and don't smell nearly as bad as goats except when wet. A herd of sheep is know as a flock and the females are called ewes. That's where they get that old expression, flock ewe.
