what are 5 main things to do to maintain a semi auto shotgun

damage by dryfiring was and is a old myth rim fires can get a flat spot from hitting the side of the chamber ,but all firing pins have a return spring that will take the impact od a dry fire ,dryfiring is a great way to practice trigger control and breathing well holding the gun steady for the shot ,you can practice this at home for hours well watching tv or what ever .it is a good way to avoid a flinch well pulling the trigger ,Dutch
 
depends on the gun...if its a remington semi, there will be some o-rings etc. in the gas system that should be prevented from drying out.
if its a fine italian model like a benelli....no real maintenance
 
It does depend on the gun. The maintenance requirements for a recoil-operated gun are different from a gas gun and within each category some models have different needs than others. I don't know the gun the OP has but any semi needs to be oiled, choke tubes should be greased and the gun should be kept clean. Pay particular attention to using it in the rain. Water in the mechanism is not a good thing so it should be dried out thoroughly.
 
As an 870 armourer I have seen 870's dry fired and placed in condition cruiser for years. Never had to replace a spring or pin. But I have to say once when I was a little fella I dry fired my uncles model 37 pump. The look I got from two uncles and my old man caused me not to dry fire again without sound reason.

The issue of lubing the chokes is not only related to the threads. I recently picked up a used o/u that had the chokes in rather tight. After some gentle persuasion, it was determined that the barrel and choke bodies had rusted together somewhat, causing the binding. Lubing those surfaces is also on the to do list.
 
your old timer verteran hunter is exactly that. he seems like he doesnt like advances in technology and general information and firearms knowledge. always oil your chokes and guns, use spray oil to your hearts desire, its not gonna gum anything up. dont bother cleaning it until it starts to jam if you want..or maybe every few hundred rounds. i use remington spray oil on all my guns, precisely because it gets into small spaces that i cant get my hands into also for the fact that my skin is so acidic i rust/corrode every metal that i touch. i bet the old fud thinks that wood stocks are always better than synthetic also. his ignorance of knowledge is incredible.

EDIT:dummy rounds are a waste of money. dry fire that b!tch all you want. unless its a rimfire..then read the manual.
 
I have an A400 xtreme. CLEAN IT is number one.
They say to lube the oil, clean the gas piston, clean the gas tube, clean old oil off bolt. THEN re oil the bolt. Grease the choke tubes.
Every year they say take the trigger out and clean it and re oil it.

DONT OVER OIL

CHEERS
 
I've heard many people say not to use wd40 spray lube on guns because it will gum it up... Not sure I've ever seen that. Rem oil should be just fine.
Always always always lube the chokes! Use oil or even anti seize (moly, copper, nickel) to be sure it won't get stuck

Not all firing pins have return springs. My SKS, for one...

Dry-firing in a great way to practice trigger control, and in modern centerfire guns it is a non-issue. If you break a spring or something dry firing a new gun, it should be easy to replace and is likely covered by warranty.

Old guns its a different story. Depending on age, condition, and amount of use over the years, springs (among other things) can get brittle. Also, there has been huge advancements in manufacturing and steelmaking in the past 100 years, so it costs very little to make a high quality spring these days. I would be avoiding anything that causes unnecessary wear and tear to a gun that I couldn't find parts for, I can tell you that much.

Last, Rimfires. It depends on the rifle, but generally you can peen the chamber face with the firing pin, which could eventually lead to a spot where the rim doesn't seal. Some models have been designed to avoid this, but not all of 'em. Check your owners manual for more info.

WD40 is a water displacer not a lubricant. The lubricating qualities in it are not meant as long term applications therefore they dry out leaving no protective coating. WD= water displacer, the 40 stands for the 40 th formula that was developed.

Not true, I have seen trigger mechanisms jammed up badly, because they were sprayed with oil, and then exposed to dust. Spray on oils are even worse with rifles, as they flow onto the bedding surfaces, and can cause accuracy issues.

I have witnessed that situation on multiple occasions. WD-40 and dust makes a terrible combination. I never use WD40 on my firearms for any reason.
