Strangest shooting problem I've ever had

I'm hoping some of you rimfire folks can help me with this.

I have a scoped Remington Nylon 66 that shoots the first shot after reloading 2 to 4 inches low.

So, if you load 10 in the tube, the first shot lands way low. The next 9 in the bullseye. Do it again, first shot low, next 9 in the bullseye. Load five, first shot low, next 4 in the bullseye. This happens every time you load the gun.

This is an ongoing problem. Over the last few months I've tried 3 different scopes and about 8 or 9 types of ammo, all with the same result. 2 of the scopes are now on other guns with no issues.

I'm confident the problem is not the shooter (me) as I don't do this with any other guns. Also, the degree the first shot is low is pretty extreme. Even I can't flinch that bad. Not every time anyway.

Any help is greatly appreciated.
 
It does sound strange, is the first round seating properly in the chamber, if its a bit loose somehow, due to a worn chamber it may cause that. Just a guess at what it may be.
 
Possibly a worn out recoil spring not seating the first round the same as the auto-loaded rounds. Could be the chamber too as mentioned above...

I don't know the 66 very well so that's all I got.
 
The way you explain it you are charging it with too much force. Next time you have it out, gently pull back the handle watching it till the bolt clears the .22 round and let it go. See if you get them all closer together.
 
When was it last cleaned, is everything back together and tight? Are you rough or gentle closing the bolt on the first round? Is there a buildup of dirt or oil in it? Is it bending the round as it chambers?
 
Thanks for all the replies.

It does it dirty or clean. I've also tried charging it ever so gently and as rough as I could with no difference. There is no build up anywhere as far as I can tell.

The last cleaning was very thorough. Took everything apart except the trigger group and it all looked brand new when it was put back together. They aren't as hard to clean as some people would have you believe.

I didn't try it without a scope, which I really should have thought of. The only comonality in testing, I realize now, is the scope rings. But I can't see how the rings could cause such a problem.
 
My suspicion on it being scope related; after reload, optic has moved somehow. After first shot, recoil has repositioned it to a 'better' position and the remaining shots are true.
Just a thought, but I doubt it's receiver, bolt or barrel related since they should not affect first shot (except for cold barrel shot, which would not apply to second mag, first round).
As already suggested, try without scope and see if you get a consistent group.
Good Luck! Cheers.
 
Well I just noticed this.

When I drop the first round into the tube, something is putting a noticable chip or gouge into the lead. On the side, a couple of mm from the nose of the bullet. Following rounds have no such mark. It appears that something is damaging the first round. When I load it slowly, rather than dropping the round in, there is no mark.

The chip is not huge, but it would probably catch the wind. The chip has a distinct edge to it, like it's hitting something quite sharp.

I'll pull it apart in the morning and see what I find.
 
Like mentionned how do you load the rifle??
You should pull the bolt back and then let it release on its own.


By your last comment it looks like your bullet is catching on the side of the chamber.

if it was a rifle with a magazine I would say that the mag is not properly inserted.

I am not too familiar with tube fed but I would suspect that the tube is not properly aligned.
 
Ya my best guess is something, like the mag moving or not lined up right when they are loaded in, it moves, and gets set back after first shot, like the mag tube follower isnt moving free enough to push the first round out fast enough and it gets jammed and lead torn off it

I'm thinking the exact opposite of the above. Semi autos are supposed to slam shut. Sounds like you are closing the action on the first round too gently. Since the round would not be well seated you might be getting poor primer ignition or case swelling but the auto loaded round gets fully seated and fires fine.

I think your on to something there..
 
I've never been truly inspired of how this rifle's action cover fits over the action. I'm just guessing here, but I suspect it has something to do with the flimsy action cover and the attached scope/rings/mount. One does not see many Nylon 66's with an optic on top of them for very long.

my two bits only...........
 
My Remington 597 dropped the first shot out of 10 as well. What I figured the problem to be was a cold barrel. So what I did was correct for the first shot and then shot the next nine on target. I won second at the gun clubs 22 shoot last winter with this firearm. Could it be the same thing?
