Clean the bore
It’s back to Beeman’s dual-caliber RS2 SS1000H today. The first step before velocity or accuracy testing is barrel cleaning, if at all possible. I don’t clean those rifles whose designs make the barrels difficult to access, like the Gamo CF-X or the TX200 Mark III, but breakbarrels are pretty easy to get at, and a rifle whose barrel comes off has got to be the easiest! So, out comes the JB Non-Embedding Bore Cleaning Compound,eddie and it’s 20 strokes through the barrel in both directions with a new brass brush. For a complete explanation of what I do, read this post. Pyramyd Air doesn’t have any .177 brass brushes in stock as I write this, but there’s nothing wrong with using a brush bought at Wal-Mart or a gun store. Nylon brushes are not good for this procedure, and .17 caliber firearm brushes will work in .177 pellet guns, as .22 caliber firearm brushes will work in .22 pellet guns. The brushes are tens of thousandths too large for the bore, so we are not looking for a precision fit.
