Shooting Left

[Hobbsy]

Hi,

Hope someone can help. I have a CZ 75b stainless which is shooting about 4" to the left at 15 yards. But if I shoot 95gr Magtech or Fiocci 100gr bullets, no problem, dead centre. Anything heavier is to the left. (All hand loads, Lovex DO32 powder) I also own a Sig Sauer P210 and have no problem with that. Any ideas ? Thanks.

So if I understand correctly the gun doesn't shoot your hand loads well? Yes?  But it shoots the factory ammo well? Could be that you will need to work up a different load for the gun or stick with what you can get commercially. Incidentally I've never seen any 95 or 100 grain factory loadings like you speak of here in the USA. Those sound like .380 loadings.

Thanks for the reply,

So far I've tried S&B & Geco 124gr factory ammo. Hand loads I've treid are 115gr Hornady XTP, 115gr.  Alsa 115gr FMJ. 123gr LOS HP. All shoot left.
The 100gr Fiocci & the 95gr Magtech are handloads (4,0gr & 4,3gr Lovex DO32). Thies work fine. Its a riddle to me !

Yes that is strange if the factory loads are that far off. Maybe try shooting the gun from a sturdy rest and see how it does. The rear sight can be adjusted to compensate for windage if need be. I would have expected the gun to be off with the handloads not the factory ammo.

Get someone else to shoot it.

Get someone else to shoot it.

Best advice.

Try putting several of each load in a mag and mix the loads up or have someone fill a  mag for you with the mixed loads.

then shoot and see what happens.

Try shooting it from a solid rest.

I've had to drift my rear sight because of shooting left on all three of my 9mm's.  If anyone else shoots them they shoot a little right. 

I think it's me.  This doesn't explain your difference in POI with different ammos though.

Shoot both from a rest and see if it's the gun or you.

Hold the gun vertically, homie!

...just messing with you!  Seriously the lighter loads may be imparting less torque therefore less influence on an improper grip.  Review the basics again re: the handgun grip and focus on the front sight.  You'll get it right I'm sure.

[Hobbsy]

Sounds plausible. I'll have to review my grip. Thanks for the reply !

I was shooting low left at first. I started applying a touch of pressure with my left thumb on the slide. that fixed it right up. now its just muscle memory and I don't even think about it

[rhart]

I shoot a little left if I'm not careful with my trigger pull on all my CZs/CZ clones as well as with my Sigs. This doesn't happen to me with a 1911 style trigger. I also use thumb pressure on the support hand side to minimize this, but when shooting groups I concentrate on trigger press.

I would think you may be gripping the gun too tight and when you squeeze the trigger you actually push the muzzle slightly left just enough to move the point of impact left. I did that years ago, I remedied this when I relaxed my strong hand enough to where when I manipulated the trigger I squeezed it straight back and didn't push it left. Squeeze til your hand shakes then relax til it stops and then relax just a tiny bit more. Then place your support hand on the grip and squeeze With a death grip or if your old enough G.I. Joe with a Kung fu grip.😄

Almost certainly trigger control.  I'm not even sure how a different load could make the bullet veer left.

Couple other things that could be a factor:

The different loading will have a different perceived recoil, and you may be "pushing" the gun to compensate for a flinch. I've seen shooters get fairly consistent results by self-compensating, but change the load, caliber or gun and they start getting different results. Dry fire practice will reveal this: put a coin or empty cartridge on the front sight. If it falls when you break the trigger, there's your culprit.

Also, if you shoot Isosceles, dropping the left elbow can send shots to the left.
