is this common with ssx choke?

[captin_hook]

I have a ssx choke for my 870sm and the choke changed my poi 9 inches to the right. I was shooting 3.5 win hv #5. Now this is at 20yds, at 30 yds I have a dead on pattern that is very nice with no holes. My 40 yard pattern was no good.. I wouldn't hunt with it. Now I ordered some hevi 13 #6, 3 inch. If my poi stays off this much, should I just assume the gun doesn't like this choke?

Do I understand correctly that it's consistently 9" to the right of POA at 20 yards but "dead on" consistently at 30 yards? Is the 40 yard pattern also consistently dead on but just not dense?

Did you fire a number of shells at each distance?

I've seen different chokes or shells change a POI, that's pretty common but I've not seen a POI vary like that, if I understand your post correctly.

I shoot a lot of those chokes and have not experienced that. I'll be interested to hear how it patterns with the 3" Hevi-13 shells.

Thanks,

Every shell and choke combo I have shot changes my poa/poi a little bit so I wouldnt be concerned, just adjust it. But here is my ssx and win hv #6 pattern.

 Yes, at 20, my poi was 9 inches to the right. At thirty it was a nice evenly dense pattern that was almost dead on. I shot the winchesters 3.5 hv, seen my pattern, thought it could be the shells so I tried some low brass bird shot and it patterned the same. That's why I made the post about the remington wingmaster HD choke.. when I bought the gun I never tried it and I was wondering if this choke would do any good with the hevi 13? I'm just going to try both and see what happens.

Sorry Clark, to answer you're questions.. I shot 3 shots at each distance, both the gun and choke were broken in and deep cleaned. I did not clean the gun or choke during the testing though.

You've got a problem somewhere.  If I am on at 40, I am on at 20.  Something just doesn't add up to me.  End cap not tight, sights moving, wad hitting lip of choke, anything.  Someone else may know, but to me I'd have to check my gun.

[captin_hook]

I thought the same thing, checked all that, cap,choke,sights were all tight. I used these shells before with just a regular full remington choke, there was no problems, I just wanted to tighten up my pattern some, so I got a ssx to try.  So nothing has changed except the choke, I'm thinking the gun just doesn't like. Nothing looks wrong with the choke and it screws in good.

I don't know then, I'd try a different choke then.  Very weird
