Can you shoot BB with the Gamo PT-85 CO2 pellet gun?

Answer 1

The Gamo PT-85 is designed to shoot Pellets not BB's. Here's why. The barrel in the PT-85 is rifled meaning it has grooved down the barrel that make the pellet spin as it leaved the barrel. Pellets have a soft skirt that catches the C02 blast. This skirt conforms to the grooves as it travels down the barrel. This spinning makes the pellet very accurate as it travels to the target.

BB's are usually fired from a smoothed bore barrel, much like a straw, BB tumble as they leave the barrel and can wander off target easily. When a BB is forced into a Pellet rifled barrel. It doesn't conform to the grooves, what it does is scrape the grooves off a little at a time. Each shot damages the barrel a little more making the rifle barrel worthless for pellets.

Forcing BB to be fired down a pellet barrel will ruin a very good rifle in a very short time. It will no longer be as accurate as it once was.
