What are your group sizes : 9L/PRO

Recommended Posts

Just wondering what are your group sizes you're getting with your 9L/PRO. If you could give me the particulars also; bullet wt. type and brand, at what distance, power factor you have it at. Original barrel in my 9L was dismall but S&W was very reponsive and sent me out another one which is different and has made it in the acceptable range for now. Waiting on the Apex configured barrel from Bar-Sto. Thanks.

My 9mm Pro shoots groups that are easily measured with a yard stick! At 50 yards with the best load I could find or make, was 18". The load was a 147 gr. JHP....... Point of aim was off the target to get the bullets to hit the target. The worst load would not print all the rounds on a bianchi tombstone target at 50 yds. I to am waiting for the Bar-Sto barrel.

I have a pair of 5" Pros, in 9mm. My original pistol shoots under 2" groups at 25 yards with Zero, 125 grain, jhp, .356, or Hornady, 124 grain, XTPs, using once-fired, Winchester brass, 4 grains of Titegroup, with an OAL of 1.12". My other Pro seems to shoot pretty horrible, 4-5" groups. I think it will be a good candidate for one of the new Bar-Sto barrels!

I shot a lot of vv320 last year, and eventhough it feels softer than Titegroup, in my gun, it isn't as accurate. I picked up a pound of Accurate #2 that I'm going to play with.

It's interesting that you would say this. I too had similar results in my guns yet many on this forum want to convince the World that VV N320 is God's gift to the shooting community. :devil:

N320 is all I've ever used, and all I ever WILL use. Other people may have different results, but I've never had any problems. I load both a 147MG JHP or a 124MG FMJ, both at 130 PF.

While I've never benched the gun, I can shoot freestyle at 45-50 feet and my groups are 1-2 inches, no problem.

Shot my first match with it Sunday. Had a lot of misses about 3 to 4" off my POA, high and left. I had previously checked it with 147 handloads and it seemed fine, but shot the match with factory 124 fmjs. Checked it this evening and the sights were in fact off a little bit. 124 grain Fiocchi, 3" 25 yards groups. 147 MG CMJ over 4.1 grains of WSF, 2.5" 25 yard group (was 130 PF in my "G34" Glock). It was very cold and windy and I was shaking in the wind, so I think it might do better when I am not frozen.

My shooting buds and I must be lucky. 2 9l's, 1 pro and 2 standards all group very well out to 25 yards. All will hold around 2-3" with most any load-factory blazer, UMC 115 grn, handloads with 124 and 147's loaded with solo and vv320 pf 130-140.

I have done some trigger work & spring changes to my M&PL9

I was shooting sub 1 second splits into an ICORE/AM1920 target 3" X-ring black dot @ 15m yesterday.

Plenty accurate for me.

125/135LRN/3.5AP50(Clays?)1.1oal. @ 132pf.

I have yet to actually bench the gun for groups, as I simply suck at it. :blush:

But I shot a 5", 5 shot group off hand at 25 yards this past Saturday-- in a competition, under the timer. I've done notably better just poking around at practice.

When the gun came back from the 'smith, he test fired a magazine at an ~8" rock @ ~60 yards, as fast as his GM skills could hit it. A direct quote: "So I guess it prints pretty well?"

Load:

MG 124 gr JHP

4.1 gr VV N320 (~131 PF)

1.140 OAL

Pretty sure I have a fairly tight barrel and chamber; I was making PF with loads that I did not imagine would have the "juice", and I start to get into the rifling at lengths that a lot of folks are able to load to with a cushion. DEFINITELY no unlocking issues, either-- running a worn 15# spring.

For me, the KKM drop in barrel made a huge difference. Not that accuracy was poor with the stock barrel (at relatively short ranges) but it is clearly better with the KKM. I can't give you a number because I have never measured a group. I shoot the gun a lot so I am sure my results are better. I don't reload 9mm so I am mostly shooting Federal and WWB 115s. Gun has Dawson adjustable sights and the Apex kit which also help.
