I guess by "Bass" you are meaning "Brass"
No it is not true. Base material of sleeve realy doesn't metter on wear, because it is coated by Chrome, the piston-is the part which is wearing out. If chrome plating done well, you can changed piston in the same sleeve many times-4-5 times at list and then you have to correct tapering little bit in sleeve and it is good to go for 5 more pistons.
