Back boring my 870

Won't a tighter choke have the same result as all the smith work?

2x.

Just change the choke for 20$. Waste of money unless your doing competition skeet/trap shooting and even there it's debated if it's even worth it.

Who was it that said this again.

Save your money, buy ammo and take a class.

You'll get much more out of it.

I removed / smoothed the forcing cone in my mossberg 500 around 10 years ago

I did not notice any change in recoil

With OO buck, it reduced the pattern by 2 1/2 inches at ten yards

I never did a before and after compairason with bird shot

I picked up a reamer from Brownells and went to work with a vice and a tapping handle
The reamer was under $100

For the 870, i would spend the $100 towards a barrel with removable chokes

For non chrome lined barrels it is probably a 1 hour job from a gunsmith
If they have the reamer, then it should be a $50-$100 job

For the unknown on the final result, buy another 870 or a used barrel with removable chokes. You can then select the appropriate chooe for the job

The pattern on 12 and 20 gauges is similar. It is pellet density that is impacted with heavier or lighter shot loads

The 20 gauge is great for closer in upland birds

With geese you tend to go to higher velocity and heavier loads to have a dense pattern at distance or for tough birds like turkeys

870

From what I have been told and have read is that a short forcing cone and or a tight choke will retard the pellets. When exiting the barrel the pellets produce a inconstant pattern, that is why when you shoot a denser pattern shot will tend to float around the shot pattern. Either more pellet holes, when parenting a shotgun, will group to the right, left, up or down.

The barrel that I might have worked on does have tubes.

Why would the 12ga. In the show that I watched knocked down a popper at 15 yards and the 20ga. Could not. If what they said was true that the loads were the same?

Keep in mind guys a choke can have the opposite affect. Some times a bunch of pellets being jammed into a smaller area so quickly causes a rebound affect making the pellets spread out more then with no choke. Not to mention making them out of round like 1911 said.

That is exactly what message I was trying to convey. Thanks.
