Benelli M1 Zero Issue

[SkyHawk]

Jeez, lighten up Nancy. Can't see a joke when it's too obvious maybe? I love a Benelli.

Yeah I have a Benelli M1 but I still thought the joke was funny

There is two red dots in the picture (Left side). One was the impact on the steel the other was the POA.

But you said that you were aiming at the railroad ties, are those on the ground? Is the steel the high dot or the low dot? Are your rounds going 4 feet high or 4 feet low?

The whole 'I aimed at the railroad ties' thing is what has me confused, since it appears they are on the ground. I am starting to wonder if you meant your rounds are going 4 feet high of aim point.

Are these the two dots?

Sorry, I was aiming at the rail road ties (large dot) to hit the steel above (small dot) so 4 ft below the target.

Note, this gun was built by Taran Tactical and they say that they do "Taran’s Signature tube and barrel point of impact correction" other than crap ammo that is the only thing I can think of.

Also I would say its 100% shooter error but I dont think it was. I dont even think you could create that much elevation change on rifle sights at that distance.

If we assume the same conditions, he will be 1 foot high at 20yd with a 50yd zero, and 1 foot low at 60yd.

What he is describing is so unusual I'm thinking this has to be an ammo problem or a bore restriction problem.

OP, these should have kicked like a mule even from the M1, did they?

It also appears Prime has taken all 12ga ammo off their site https://www.primeammo.com/ammunition/12-gauge.html

Try federal reduced recoil loads as they are a known quality load. I think it is an ammo issue as many have said.

Yes shooting 4 ft high at 50 meters.

Betting he’s not dead on at 20. Small mistakes get magnified as you go out.

I went back to look at it and I would say it was shooting dead on around 15 meters.

Lets just say the rifle was zeroed at 10 meters at you could create a 4ft jump at 50 meters.

I think I need a new barrel, new sights or new ammo.

><

Don't know how much experience you have with open rifle sights....but

Did ya check to see if the rear sight was in the same position between to two ranges?

Next is, are you flinching?

Was just reading on a 3 Gun forum about Nordic Barrel camps and issues with Benelli barrels shooting high. Might have to do some research and either get a new barrel. tug on this one (maybe) of put an RMR on it so I can adjust POI.

Iron sight calc says you need around .45" adjustment, either the rear sight comes down or the front sight comes up - to correct for a 4 foot high shot at 50 yards. I would try different slugs before anything else though.

Can we see a pic of your front and rear sights?

I’d still re zero at 50. I bet you’ll be fine at closer distances. No projectiles rise.

These sights are not adjustable for elevation. The rear sight would have to be replaced. And Benelli doesn't make them. Here is a thread with someone else in the same boat, looking for a taller rear for a 50yd zero.

But here is another that said his shots were low

That thread also has guys modifying the dovetail to accept 1911 or 10/22 sights.


OP has such a severe vertical offset between 20 and 50yds that I think something must be wrong. It is true that projectiles do not rise if the barrel is pointed level, but they do in fact travel above the sight line. And a bent barrel would wreak havoc on sighting, and a barrel that is pointed up will definitely see the projectile rise, far above the sight line.

We really need to see pics of the sights but I think something cold be very wrong.

Given all the op’s posts, I have a pretty good suspicion of what’s wrong. That said, I didn’t know his sight weren’t adjustable.

To your edit... if he’s actually dead on at 20, I don’t see how a projectile can rise after that. Makes no sense to me.
