Picked up this 5mm Sheridan/Benjamin/ Crosman. 2002 model. Did a trigger job. Lube and basic exterior cleaning. It started out at 650fps with eight pumps. Using 11.42 grain H&N FTT. Accuracy was mediocre with occasional flyers. So, I went to do a deep clean on the barrel. Using Birchwood Casey ”honeycomb” patches (best patch I’ve ever used) Shooters Choice bore cleaner, then Never Dull cotton brass polish and finally Tryflo lubricant. Probably an hour and 60-70 patches later I finally got a smooth bore and a bench full of green, then black and finally clean patches. Now with eight pumps I’m getting over 700fps. 645 with six pumps. And no flyers. Spot on accuracy. This gun is nearly 25 years old. Doesn't appear to have ever been shot. The barrel had just gone green with tarnish. Very important to clean these brass barreled classics to keep the tarnish from becoming a power loss and accuracy issue. FWIW.

Thanks for that. I have never cleaned my Sheridan's barrel. I'd bet that it wasn't cleaned before I got it, and it's a '64.

The earlier barrels were made of phosphor-bronze for slickness, but I'm not sure about the later ones.

Cheers,

The later ones are probably also. But still can tarnish. I’ll bet you keep getting green out for a time.

Looks like just out of the box.

Great post. I owned a mid-eighties blue and an early nineties silver that I bought at the factory. I just know they shot great. Sold them both around 2005. You don't know what you got till it's gone. They were terrific and potent shooters. Those 5 mm slugs were hard and punched through a lot.
