What weight bow is needed to shoot 70m?

Well, there are lots of things to take into consideration – you should shoot the highest poundage that you can comfortably control. There is some evidence that you could go as low as around the 30lb mark depending on the following points (see next paragraphs). In my experience most people will be shooting around 36lb+.

In addition to increasing your limb weight (which might involve a few trips to the gym but will definitely involve a lot of practicing with your set up) there are a lot of additional things that you can do to help yourself gain the maximum possible shooting distance for the lowest poundage of limbs. It is easier to shoot more efficient limbs so you may be able to control more weight with less exertion if you spend a bit more money (OK maybe quite a lot more money). For example Border limbs explain it thus, “At Border we offer a synthetic composite core and is denoted by an H in the HEX6.5 (discontinued) and HEX6.6 model series. This offers approximately 4fps to 8fps more arrow speed than their multi-laminated bamboo/wood equivalent. This difference is roughly equivalent to 1lb to 1.5lbs of bow weight performance… the choice of core will not affect the draw-force curve at all, the draw-feel will remain the same irrespective to the core material chosen.”

Arrows also make a huge difference – the faster and lighter the arrow the further it will easily and accurately go. You want the best spin wings, curly vanes, G nocks and something made out of carbon (you won’t be shooting Jazz arrows at 70m).

Spend a lot of time tuning your bow (we still like the Simon Needham book ‘Steps to Success’ for this). You want the most efficient string (e.g. fast flight) and you’ll want some Beiter nock points.
