870 Police Magnum - First 20

Thanks for the detailed reply BCshooter. I think you may have exposed my problem. I stored the gun after passing an oily patch through the barrel. Me thinks (hopes) that the oil settled into the chamber area as it was stored standing upright and caused my extraction issue. I will definitely be taking it apart and cleaning the packing grease of ALL components.

What's the best product for removing packing grease ? Hoppe's 9 Solvent ?

The post right above this covers it. I might also mention is why I don't like express models. Wingmasters are metal trigger groups and HOT HOT water does the trick. If it's hot enough it heats up the metal and evaporates. If you have compressed air (I'd have a little Canadian tire air compressor just for this reason) you can was with hot water and dish soap then blow out whatever is left. Simple green also works. But if you have one of those fat cotton bore cleaners (comes in every kit) just use solvent and stroke it and spin it inside the chamber and if it catches on anything (as in rips the cotter a bit) then you know something is wrong inside the chamber and I personally would send it back at that point.

If your barrel is removed and you pull the spring out of your mag tube a good shot of crud cutter(Canadian tire. It's the same thing as brake cleaner) will loosen a lot of sh*t that's clinging on. Just don't let that stuff touch anything that isn't metal. I us it for the inside of old recovers and mag tube only or if I am going to paint something.

And my tip to you and anyone else is buy a chamber brush for every caliber you own. Don't need to use it often but it's a part of guns I neglected for a long time.

And you're welcome for the detailed post. I honestly come to read comment sections like this so I can learn about my fire arms more. I also just looked into this model and it's pretty much a tactical wingmaster. Less plastic and pretty much all metal parts.

That all depends on what you shoot for hulls many of the quality target hulls are still brass. Brass height does make a difference on cycling a pump
Try resizing low brass when reloading and then high brass and tell me there was no forming differences in the chamber when fired which can cause resistance over the length

Cheers

The OP isn't asking about, or shooting, reloads.

If your reloads are hard to chamber, that's on you. If you do it properly, no, there's no difference. I'm not sure what your point is? That you have to resize? Well, yeah. That's not a functional difference. It's only an issue if you don't follow proper reloading procedures.

Brass is basically decorative, as I say. It's absolutely no indication of quality or anything remotely like that.

Winchester has some info for your edification:

Today’s plastics are fully capable of holding primers and containing powder, wads and shot through the life of the shell, including firing, but shotgunners are firmly wedded to the brass shotshell base. Not only that, they still associate power with an ever higher brass base, which is why today’s target and light game shells are still loaded in low-brass hulls and magnum shells are loaded in high-brass hulls. It isn’t necessary, but it does make it easier to determine relative power levels of shells at a glance.

So, like I say, no functional difference and basically decorative.

Cheers.

You wanna clean the grease?
Use some Carb cleaner from Crappy tire.
Then spray liberally with G-96.

Nor am I.

My point is if one resized a MODERN high brass vs low you will see how different they perform in a chamber after firing and the different amounts they deform thus ,making TODAY'S high brass harder to eject in a pump which you said there is no difference. NOT TRUE
No where did I say high brass is a requirement for function it never was after paper hulls which I would be shocked that you ever reloaded them

The difference is in the ejection due to how much more deformed area you have to remove from the chamber in a high brass vs low especially in most if not all makes of modern high brass hulls which are not brass but steel/ tin and get all out of shape when fired so much so they have to be resized in a collet style resizer IF they were reloaded. That was not seen years ago with high brass in fact the deformation was less but they were quality hulls then
Also you said hulls are just all brass plated today which is not true. Quality target hulls are still brass

Your words
Both statements are wrong

Cycling lower power shells may be an issue with some semi autos, but that has nothing to do with brass height. It definitely has nothing to do at all with cycling through a pump.


The "brass" (actually brass plated steel) on shotgun shells is basically decorative.

Like before I don't use the internet for my information AS YOU DO, but hands on real life experience and this is simple stuff Mike even for you :)
Cheers

That is legit about the dopiest thing I've read from you, and it's a very high bar.

Do you really think that's true? You really believe it's true that because a shell is harder to resize it's harder to extract?

Do you know what springback is?

Tell you what. Go set up an experiment and get us some numbers...

Seems like it.

Where would one find some buck shot ballistic charts
Thanks for the help

Check. Mate.

The problem is its a new 870 and remington makes crap guns now with horrid quality control. I have had a few models and they were all picky with ammo. For what you spend on these you shouldnt have to polish anything. They should rock right out of the box.

I switched to the Mossberg 590 and 590A1 and have never looked back. The will eat any type of ammo are reliable and tough as nails. Not as pretty as the 870s but... they work much better imo. If you had purchased an older second hand 870 that was made right, you would have a nice shotgun.

Ya OK. Sorry you cannot grasp what takes place to the hull after firing in the chamber .Spring back comes into play does it with these crap modern shotgun hulls??? We are not talking brass rifle cartridges here or full brass hulls and if we were you would know it can take 24 hours to return to original diameter. That sure helps ejection
Unreal the level of inexperience here or maybe?? Keep changing your post maybe you may hit on something worthwhile eventually
Cheers

Oh, buds you crack me up. Love ya. I know you're just dying to be right but you can't just make up goofy stuff and have it magically become true - you're not Cliff and this isn't Cheers.

I should start making a list like they do for Trump... "Anything smaller than 00 buck isnt suitable for deer at any range... you can't shoot a deer with muzzleloader buckshot... high brass shells are harder to extract..."

Dood, I even went out and blasted a deer with 4 buck just for your education and I didn't even get a thank you card. Harumph.
 
my Winchester trench gun also failed to eject that challenger 00buck I noticed the base of the brass was denting on the ejector thus not ejecting

Told you before I am not your bud or friend.:). Not sure what to say on the love ya comment


Maybe you should check your internet seems it agrees with my goofy stuff as noted below which was the only point I was making but you could not see that since you are still butt hurt over the buckshot debate we had which was not one of your finer moments either.

I quote :

If the shell has a steel base like those Fiocchis etc, the steel expands but unlike true brass, it doesn't return back to it's original size. With the low steel brass colored style, it doesn't expand as much but high steel colored brass style expands more and causes shells to get stuck in the chamber

Aw buds, no worries. It wasn't a a debate though, because there wasn't anything to argue. I was and am right; I was doing my best to educate you despite stubborn resistance.

Anyway, neat quote from someone else as misinformed. The first giveaway there is that he thinks brass springs back to it's original size. Figured you might have picked up on that. Do I have to point out it doesn't, but rather springs back slightly from it's expanded size? Like, that's why it's called spring back and not spontaneous resizing.

Thinking that extraction issues with high brass shells are caused by the height of the brass is like thinking it's the Ferrari badge that makes a car go faster. You're mixing up correlation and causation. I can think of one pretty obvious reason a high brass shell may be harder to extract, and it has nothing to do with how far up the steel goes. Care to venture a guess? As a big hint, do you think you would or would not have the same issue if you loaded a low brass shell with a high brass charge? Why on earth would the extra height of brass cause it to expand "more"? That's not even consistent with what YOU'RE saying, which is that more brass plated steel drags on the chamber and makes it harder to eject. Did you really read that and think it's the brass height making the shell expand more? Which do you think has higher lubricity - brass plated steel or the plastic?

Uh, so you're saying you don't worry about admitting when you're wrong because only smart people do that?

Er... ok, well I guess we're in agreement.

Your argument may have been stronger if you hadn't picked a meme from an Indonesian practitioner of Neuro-linguistic programming quackery. Just saying.

Good stuff.

You know, I'd kind of be disappointed if eventually your nonsense didn't devolve into memes and emojis.

It's a pretty good indication that you've run out of nonsense to spout and perhaps, maybe just maybe realize you're out to lunch.

And so what if I like a bit of butthurt? My ###ual proclivities are between me and the other six of us in bed.
