If I were you I'd take a look at Badger Barrels as well. The guy makes custom rifle barrels as well as shotgun slug barrels. I have one on my 1187. I absolutely love mine. They have the fastest twist available. and for an 870 they are only $209. Here is the info listed on their web page.
Shotgun Barrels:
Made in the USA and We mean it.
Some companies claim to be made in the USA but in reality they still deal with foreign parts and labor. That does not support the USA or its work force. All products manufactured by Badger Barrels are made in the USA.
1-26 “Fast Twist” Cut Rifling.
The fastest 12-gauge rifling in the industry. We work with the major Ammunition companies to make our barrels perform flawlessly with the new high speed Sabot slugs.
Match Grade Steel
We use the finest Match Grade Steel to ensure every barrel is consistent in its performance.
Machined Cantilevers
No Castings here. Every one of our cantilevers is machined to exact specification out of Match Grade Steel. Every scope locks in for a perfect fit.
Sight Systems
We use the very best fiber optic rifle sights available. All sight parts are steel to withstand years of field use.
Fit and Function
Every one of our barrels goes through a rigorous inspection at every step of manufacturing to ensure smooth fit and function with unbelievable accuracy for the customer.
Performance
In independent testing using factory ammo, our 20 Gauge test barrels cut 4-inch holes at 200 yards. The 12 Gauge barrels had the same groups at 150-175 yards. Currently, we do not have the 20 Gauge barrels in production, but watch this sight for updates.
Information - Use of Fast-Twist Slug Barrel
NOT FOR USE WITH LEAD SLUGS - You will not like the performance since the barrels will lead up severely. Lead slug ammunition is meant for smooth bore or very slow-twist rifling. It is fairly easy to recommend types of shells for pumps and bolt actions because of the solid lockup. But with autos, due to the different lock-up types, different action spring tensions, and different locations of the gas ports in relation to the front of the chamber, ammunition recommendation is not as easy. Different ammunition makers use different propellants even though none load hotter than 12,000 PSI. Due to the different types of propellants, peak pressure occurs at different locations in the barrel. With the gas ports being located in different areas from one model to the next, you must find the brand of ammunition that most closely matches your firearm needs. The bolt tightness or the spring tension changes the accuracy. Six out of ten guns of the same type may like one brand, but the other four may all take different types to get the same performance. The hammer strike or even the extractor pulling the bolt to the right changes the difference in the powder ignition. They weren't built as match rifles, but the with right barrel and ammuntions, they can shoot like them.
Too many peices of lead whip'n around for me!
