Is there an advantage to getting the tight tolerance barrels from Battlers connection? I am asking about any advantage such as: fps, distance, barrel wear or damage avoidance?
Biggest difference is FPS is much higher than common brass tubing of .185 ID. Easiest way to make your guns BARK.
Much better penetrating power than 'loose tolerance'! I ordered a bunch of them from Strike Models before they went out of business. I used to make tight tolerance barrels from thick walled brass tubing (same dimensions as the steel) but the local metals supplier went out of business.
In our testing, we saw an average increase of around 30 fps using the tight tolerance barrels, vs the standard barrels we sell. 220-230 vs 250-260 fps. We shot 100 BB's in the same gun setup, and just swapped barrels. Some of course were a little lower, or higher, if I remember right we dropped the 10 lowest, and highest, and Averaged the 80 that were left.
so they'd be good for adding a bit of oompf to sidemounts for better below waterline penetration after passing through the water column, I assume. Were shot group patterns tested? I assume they'd be tighter.
We did test at around 2 ft, good for Protected Cruiser fire. Went from 4 inches, to around 2 inch pattern. The rifled barrels Don and I use, were 1/2 inch pattern. Kind of weird with round balls, but saw the same results each time we tested. .177 barrel blanks cut down.
