Is you biller an LTD model or a regular one. You can tell if you have a plastic handle with the wood sections of the gun on either side of the plastic piece it is a regular biller. If it is one long continuous piece of wood with the plastic handle carved into the wood it is an LTD model.
You can increase your range by adding a third band. I have 3 bands on my 54" biller and it gave it more power and range.
You can also buy a longer front wood piece for your biller and change it from a 42 to a 48 or a 54.
You could probably go to a slimmer, smaller diameter shaft to get some more range but if you do so don't use 3 bands.
You could start to freeshaft with the gun. Freeshafting will give you more range.
Hey Ed,
You said you know about billers. How can I get more distance outta my 42. I wanted to buy a new gun but I'm lacking on the cash flow. Any suggestions??
