Cx4 Range report
I said I'd report on the performance of
La Contessa Luigina once I had 1000+ rounds through it, and well, I'm a little late, but here it is. I just had so much fun with it, to the tune of 1590 rounds in 5 weeks!
First thing to know: beautifully reliable. I've had two spent casings that jammed in the ejection window after their extraction, and that's it. I've used 10 kinds of commercial 9mm ammunition in 105, 115 and 124gr, with brass or aluminum cases and
La Contessa ate them all without a hitch. No duds, no half-feeds, no stovepipes, everything went flawlessly.
Second thing to know: the trigger is horribly stiff. It's a two-stage, where you'll squeeze with no resistance for a bit, then encounter the WALL of resistance. I don't have the tool to easily measure it, but comparing with other rifles I've shot during this period, I'd estimate that the Cx4 trigger is at 10 pounds or more. You get used to it, but it's a challenge to keep the sights on target while squeezing that hard.
Accuracy? Using a cheap NCStar bipod, I regularly attained 4-5 MOA. I thought I could do better, but the question that bugged me was "how much is the rifle, how much is the ammo and how much is my fault?". So this weekend I set out to answer that niggling thing.
I obtained a shooting rest (cheap Remington model, the damned tightening screw stripped itself off after half an hour of use), eight different models of commercial ammo and set myself to shoot 20 rounds (2 mags) of each ammo type in its own target. Then I'd ignore the outermost two holes and measure the 18-holes group for size. All shooting was done with the forestock on the rest and a sand bag for the stock, at 50 yards, using 4x magnification on the scope.
Results:
Winchester | White Box | 115gr FMJ | 7.2 MOA |
CCI | Blazer Aluminum | 115gr FMJ | 6.4 MOA |
CCI | Blazer Brass | 115gr FMJ | 8.0 MOA |
Geco | | 124gr FMJ | 4.8 MOA |
Federal | American Eagle | 115gr FMJ | 6.6 MOA |
Federal | American Eagle | 124gr FMJ | 5.4 MOA |
Remington | UMC | 115gr MC | 6.6 MOA |
Remington | UMC | 124gr MC | 8.2 MOA |
A note: I actually tested the CCI Blazer Aluminum twice, because the first grouping size was 9.0 MOA which did not match my previous experience with this ammo. 8.0 MOA on CCI Blazer Brass does, however, reflect my previous (not very happy) experience with that ammo.
That Swiss Geco ammunition impressed me sufficiently to decide to test it further. I took the carbine off that broken rest, re-installed my cheap NCSoft bipod and shot without a sandbag under the stock. I shot 6 x 5 rounds on visicolor 5-inches target, and this is the result:
I shot the groups left to right (top row are groups 2-4-6) Groups 1 and 5 are nothing to write home about. Group 2 is about 1.75", group 3 is 2.00", group 4 is 1.5" and group 6 an even inch wide... meaning I finally shot a 2 MOA group with a 9mm pistol cartridge!
So what's the conclusions for all that?
1. Highly addictive hobby. The zen of the shot is fun as hell and I may soon need therapy (not that I didn't know this after 30+ years in the army, mind you...

) In fact, gotta slow down: this is not a sustainable ammo expenditure rate unless you're a doctor, a lawyer or have a corporate budget for that sort of things. And no, I'm not into reloading 9mm.
2. Budget-priced ammo is generally pretty much similar in accuracy. At pistol ranges (10-25 yards), only a professional (or truly hard-bitten enthusiast) would notice a difference. I can expect a 4-5 MOA group at 50 yards if I apply myself. But the CCI Blazer Brass 115gr and Remington UMC 124gr seem to be a little below the others in performance, still. I'll avoid them from now on.
4. The Swiss Geco ammo seems consistently performing very well. I'm going to buy more and confirm that empirically. Then I'll try to find some match-grade FMJ and see what I can do with it.
5. The Cx4 may like 124gr ammo more than 115gr... It's a 19 3/4" barrel with a 1 in 10" twist. I think I need more testing on this one. And with 147gr ammo, too. Much mooooooore testing..... yess.....
VIVA LA CONTESSA!
