Non choked shotgun barrel

trg42wraglefragle · March 18, 2011, 07:33 AM

Hi all.
I'm wanting to get a new barrel for my shotgun, a shorter one (for my 870).
But because of where I live know where sells replacement barrels because its not much less than buying a whole new gun.
But I found a place thats doing a deal on a 870 that comes with two barrels.
I'd just sell the gun with one barrel and keep the other one, the one i'd keep is a 20 inch barrel with open sights, but it has no choke and is smooth bore.

My question is, what will the barrel be equivalent of, a quite open choke or a tight choke? I'm guessing its for slugs seeings how it has sights.
Also would a gunsmith be able to alter the barrel to accept changeable chokes?

Thanks all

It's called cylinder bore and that is no choke at all. I sent mine in to be threaded and put an IM choke on it, more accurate with the choke than it was without.

Possibly, if he's purchased the appropriate tools. I've only trusted a local gunsmith once, and was disappointed. It was a target barrel and he'd failed to notice that it was factory over-bored. Instead of having someone who occasionally installs interchangeable choke, look for someone who does it a lot. Ask at your local shooting club, there may be a noted choke man in NZ?

I know that its no choke at all, but what would the pattern compare to?
Would it be quite tight or an open pattern?

Cylinder will have the most open pattern.

And it's impossible to say with any certainly whether or not after-purchase screw-in chokes could be done.
The barrel walls on the Remingtons vary too much in thickness. Can't tell till you get the barrel to the mechanic.
